Abstract. Dry conditions associated with El Niño and a positive Indian Ocean Dipole (IOD) are known to have caused major fire pollution events and intense carbon emissions over a vast spatial expanse of Indonesia in October 2006 and 2015. During these two events, a substantial increase in carbon monoxide (CO) mixing ratio was detected by in-situ measurements at Lulin Atmospheric Background Station (LABS, 23.47° N 120.87° E, 2,862 m ASL) in Taiwan, the only background station in the subtropical western North Pacific region. Compared to the long-term October mean (2006–2021), CO was elevated by ~47.2 ppb (37.2 %) and ∼36.7 ppb (28.9 %) in October 2006 and 2015, respectively. In this study, plausible pathways for CO transport from Indonesia to LABS are delineated by using MOPITT CO observations and MERRA-2 reanalysis products (winds and geopotential height (GpH)). Two simultaneously occurring transport pathways were identified: (i) horizontal transport in the free troposphere and (ii) vertical transport through the Hadley circulation (HC). The GpH analysis of both events revealed the presence of a high-pressure anticyclone over the northern part of the South China Sea (SCS), which played an important role in the free tropospheric horizontal transport of CO. In this scenario, CO in the free troposphere is transported on the western edge of the high-pressure system and then driven by subtropical westerlies to LABS. Simultaneously, uplifted CO over Indonesia can enter the HC and transfer to subtropical locations such as LABS. The vertical cross-section of MOPITT CO and MERRA-2 vertical pressure velocity supported the transport of CO through the HC. Further, the results revealed a distinct HC strength in two events (higher in 2006 compared to 2015) due to the different El Niño conditions. Overall, the present findings can provide some insights into understanding the regional transport of pollution over Southeast Asia and the role of climate conditions on transport pathways.

Abstract. Primary emissions from wood and pellet stoves were aged in an atmospheric simulation chamber under daytime and nighttime conditions. The aerosol was analyzed with the online Aerosol Mass Spectrometer (AMS) and offline Fourier transform infrared spectroscopy (FTIR). Measurements using the two techniques agreed reasonably well in terms of the organic aerosol (OA) mass concentration, OA:OC trends, and concentrations of biomass burning markers – lignin-like compounds and anhydrosugars. Based on the AMS, around 15 % of the primary organic aerosol (POA) mass underwent some form of transformation during daytime oxidation conditions after 6–10 hours of atmospheric exposure. A lesser extent of transformation was observed during the nighttime oxidation. The decay of certain semi-volatile (e.g., levoglucosan) and less volatile (e.g., lignin-like) POA components was substantial during aging, highlighting the role of heterogeneous reactions and gas-particle partitioning. Lignin-like compounds were observed to degrade under both daytime and nighttime conditions, whereas anhydrosugars degraded only under daytime conditions. Among the marker mass fragments of primary biomass burning OA (bbPOA), heavy ones (higher m/z) were relatively more stable during aging. The biomass burning secondary OA (bbSOA) became more oxidized with continued aging and resembled those of aged atmospheric organic aerosols. The bbSOA formed during daytime oxidation was dominated by acids. Organonitrates were an important product of nighttime reactions in both humid and dry conditions. Our results underline the importance of changes to both the primary and secondary biomass burning aerosols during their atmospheric aging. Heavier AMS fragments seldomly used in atmospheric chemistry can be used as more stable tracers of bbPOA and in combination with the established levoglucosan marker, can provide an indication of the extent of bbPOA aging.
Impact of phase state and non-ideal mixing on equilibration timescales of secondary organic aerosol partitioning
Authors: Schervish Meredith , Shiraiwa Manabu
Published: October 2022

Abstract. Evidence has accumulated that secondary organic aerosols (SOA) exhibit complex morphologies with multiple phases that can adopt amorphous semisolid or glassy phase states. However, experimental analysis and numerical modeling on formation and evolution of SOA still often employ equilibrium partitioning with an ideal mixing assumption in the particle phase. Here we apply the kinetic multilayer model of gas-particle partitioning (KM-GAP) to simulate condensation of semi-volatile species into a core-shell phase-separated particle to evaluate equilibration timescales of SOA partitioning. By varying bulk diffusivity and activity coefficient of the condensing species in the shell, we probe the complex interplay of mass transfer kinetics and thermodynamics of partitioning. We found that the interplay of non-ideality and phase state can impact SOA partitioning kinetics significantly. The effect of non-ideality on SOA partitioning is slight for liquid particles, but becomes prominent in semi-solid or solid particles. If the condensing species is miscible with low activity coefficient in the viscous shell phase, the particle can reach equilibrium with the gas phase long before the dissolution of concentration gradients in the particle bulk. For the condensation of immiscible species with high activity coefficient in the semisolid shell, the mass concentration in the shell may become higher or overshoot its equilibrium concentration due to slow bulk diffusion through the viscous shell for excess mass to be transferred to the core phase. Equilibration timescales are shorter for the condensation of lower volatility species into semisolid shell; as the volatility increases, re-evaporation becomes significant as desorption is faster for volatile species than bulk diffusion in semisolid matrix, leading to an increase in equilibration timescale. We also show that equilibration timescale is longer in an open system relative to a closed system especially for partitioning of miscible species; hence, caution should be taken when interpreting and extrapolating closed system chamber experimental results to atmosphere conditions. Our results may reconcile apparent discrepancies between experimental observations of fast particle-particle mixing and predictions of long mixing timescales in viscous particles and provide useful insights into description and treatment of SOA in aerosol models.
How well does a convection-permitting climate model represent the reverse orographic effect of extreme hourly precipitation?

Published: October 2022

Abstract. Estimating future short-duration extreme precipitation in mountainous regions is fundamental for risk management. High-resolution convection-permitting models (CPMs) represent the state-of-the-art for these projections as they resolve convective processes key to short-duration extremes. Recent studies reported a decrease in the intensity of extreme hourly precipitation with elevation. This “reverse orographic effect” could be related to processes which are sub-grid even for CPMs. It is thus crucial to understand to what extent CPMs can reproduce this effect. Due to the computational demands, however, CPM simulations are still too short for analysing extremes using conventional methods. We introduce the use of a non-asymptotic statistical approach (Simplified Metastatistical Extreme Value, SMEV) for the analysis of extremes from short time slices such as the ones of CPM simulations. We analyse an ERA-Interim-driven COSMO-crCLM simulation (2000–2009, 2.2 km resolution) and we use hourly precipitation from 174 rain gauges in an orographically-complex area in Northeastern Italy as a benchmark. We investigate the ability of the model to simulate the orographic effect on short-duration precipitation extremes as compared to observational data. We focus on extremes as high as the 20-year return levels. While an overall good agreement is reported at daily and hourly duration, the CPM tends to increasingly overestimate hourly extremes with increasing elevation implying that the reverse orographic effect is not fully captured. These findings suggest that CPM bias correction approaches should account for orography. SMEV capability of estimating reliable rare extremes from short periods promises further application on short time-slice CPM projections, and model ensembles.
Reviews and syntheses: Use and misuse of peak intensities from high resolution mass spectrometry in organic matter studies: opportunities for robust usage

Published: October 2022

Abstract. Earth’s biogeochemical cycles are intimately tied to the biotic and abiotic processing of organic matter (OM). Spatial and temporal variation in OM chemistry is often studied using high resolution mass spectrometry (HRMS). An increasingly common approach is to use ecological metrics (e.g., within-sample diversity) to summarize high-dimensional HRMS data, notably Fourier transform ion cyclotron resonance MS (FTICR MS). However, problems arise when HRMS peak intensity data are used in a way that is analogous to abundances in ecological analyses (e.g., species abundance distributions). Using peak intensity data in this way requires the assumption that intensities act as direct proxies for concentrations, which is often invalid. Here we discuss theoretical expectations and provide empirical evidence why concentrations do not map to HRMS peak intensities. The theory and data show that comparisons of the same peak across samples (within-peak) may carry information regarding variation in relative concentration, but comparing different peaks (between-peak) within or between samples does not. We further developed a simulation model to study the quantitative implications of both within-peak and between-peak errors that decouple concentration from intensity. These implications are studied in terms of commonly used ecological metrics that quantify different aspects of diversity and functional trait values. We show that despite the poor linkages between concentration and intensity, the ecological metrics often perform well in terms of providing robust qualitative inferences and sometimes quantitatively-accurate estimates of diversity and trait values. We conclude with recommendations for using peak intensities in an informed and robust way for natural organic matter studies. A primary recommendation is the use and extension of the simulation model to provide objective, quantitative guidance on the degree to which conceptual and quantitative inferences can be made for a given analysis of a given dataset. Without objective guidance, researchers that use peak intensities are doing so with unknown levels of uncertainty and bias, potentially leading to spurious scientific outcomes.
Measurement Report: Rapid changes of chemical characteristics and health risks for high time-resolved trace elements in PM2.5 in a typical industrial city response to stringent clean air actions
Authors: Li Rui , Peng Meng , Zhao Weidong , Wang Gehui , Hao Jiming
Published: October 2022

Abstract. Atmospheric trace metals entail significant damages in human health and ecosystem safety, and thus a series of clean air actions have been implemented to decrease the ambient element concentrations. Unfortunately, the impact of these emission control measures on element concentrations in fine particles remained poorly understood. In our study, the random forest (RF) model was applied to distinguish the effects of emission and meteorology to trace elements in PM2.5 in a typical industrial city named Tangshan based on a three-year (2017–2020) hourly field observation. The result suggested that the clean air actions have facilitated the dramatic decreases of the deweathered concentrations of Ga, Co, Pb, Zn, and As by 72 %, 67 %, 62 %, 59 %, and 54 %, respectively. It is attributable to the strict implementation of “coal to gas” strategies and optimization of industrial structure and layout. However, the deweathered levels of Ca (8.3 %), Cr (18.5 %), and Fe (23 %) only displayed minor decreases, indicating that the emission control measures for ferrous metal smelting and vehicle emission were not very effective. The positive matrix factorization (PMF) results suggested that the contribution ratios of biomass burning, non-ferrous metal smelting, coal combustion, ferrous metal smelting, heavy oil combustion, and traffic-related dust changed from 5 %, 17 %, 20 %, 15 %, 9 %, and 34 % to 7 %, 13 %, 15 %, 14 %, 10 %, and 41 %, respectively. To date, no significant noncarcinogenic and carcinogenic risks were observed for all of the elements, while both of As and Pb still showed relatively high health damages. It was proposed to further cut down the combustion-related emissions (e.g., As and Pb) because it showed the highest marginal health benefits. Besides, the control of traffic-related emissions might be a key abatement strategy to facilitate the reduction of elements in fine particles.

Published: October 2022

Abstract. Multiple landslide events occur often across the world which has the potential to cause significant harm to both human life and property. Although a substantial amount of research has been conducted to address mapping of landslides using Earth Observation (EO) data, several gaps and uncertainties remain when developing models to be operational at the global scale. To address this issue, we present the HR-GLDD, a high resolution (HR) dataset for landslide mapping composed of landslide instances from ten different physiographical regions globally: South and South-East Asia, East Asia, South America, and Central America. The dataset contains five rainfall triggered and five earthquake-triggered multiple landslide events that occurred in varying geomorphological and topographical regions. HR-GLDD is one of the first datasets for landslide detection generated by high-resolution satellite imagery which can be useful for applications in artificial intelligence for landslide segmentation and detection studies. Five state-of-the-art deep learning models were used to test the transferability and robustness of the HR-GLDD. Moreover, two recent landslide events were used for testing the performance and usability of the dataset to comment on the detection of newly occurring significant landslide events. The deep learning models showed similar results for testing the HR-GLDD in individual test sites thereby indicating the robustness of the dataset for such purposes. The HR-GLDD can be accessed open access and it has the potential to calibrate and develop models to produce reliable inventories using high-resolution satellite imagery after the occurrence of new significant landslide events. The HR-GLDD will be updated regularly by integrating data from new landslide events.
Transitional rock glaciers at sea level in northern Norway

Abstract. Rock glaciers are geomorphological expressions of permafrost.
Close to sea level in northernmost Norway, in the subarctic Nordkinn
peninsula, we have observed several rock glaciers that appear to be active
now or were active in the recent past. Active rock glaciers at this elevation have never before been described in
Fennoscandia, and they are outside the climatic limits of present-day
permafrost according to models. In this study, we have investigated whether
or not these rock glaciers are active under the current climate situation.
We made detailed geomorphological maps of three rock glacier areas in
Nordkinn and investigated the regional ground dynamics using synthetic aperture radar interferometry (InSAR). One of the rock glaciers, namely the
Ivarsfjorden rock glacier, was investigated in more detail by combining
observations of vertical and horizontal changes from optical images acquired by airborne and terrestrial sensors and terrestrial laser scans (TLSs). The subsurface of the same rock glacier was investigated using a combination of electrical resistivity tomography (ERT) and refraction seismic tomography (RST). We also measured ground surface temperatures between 2016 and 2020, complemented by investigations using an infrared thermal camera, and a multi-decadal climatic analysis. We mapped the rock glaciers in the innermost parts of Store and Lille
Skogfjorden as relict, while the more active ones are in the mouths of both
fjords, fed by active talus in the upper slopes. Several of the rock
glaciers cross over both the Younger Dryas shoreline (25 m a.s.l.) and the Early to Mid-Holocene shoreline at 13 m a.s.l. Both InSAR and optical remote sensing observations reveal low yearly movement rates (centimetres to millimetres per year). The ERT and RST suggest that there is no longer permafrost and ground ice in the rock glacier, while temperature observations on the front slope indicate freezing conditions also in summer. Based on the in situ temperature measurements and the interpolated regional temperature data, we show that the mean annual air temperature (MAAT) of the region has risen by 2 ∘C since the late 19th century to about 1.5 ∘C in the last decade. MAATs below 0 ∘C 100–150 years ago suggest that new rock glacier lobes may have formed at the end of the Little Ice Age (LIA). These combined results indicate that the Nordkinn rock glaciers are
transitioning from active to relict stages. The study shows that
transitional rock glaciers are still affected by creep, rock falls, snow
avalanches, etc., and are not entirely dynamically dead features. Our
contrasting results concerning permafrost presence and rock glacier activity show the importance of a multi-methodological approach when investigating slope processes in the edge zones of permafrost influence.

Abstract. Aviation aims to reduce its climate impact by adopting trajectories, that avoid those regions of the atmosphere where aviation emissions have a large impact. To that end, prototype algorithmic climate change functions can be used, which provide spatially and temporally resolved information on aviation’s climate impact in terms of future near-surface temperature change. These alogorithmic climate change functions can be calculated with meteorological input data obtained from e.g. numerical weather prediction models. We here present an open-source Python Library, an easy to use and flexible tool which efficiently calculates both the individual algorithmic climate change functions of water vapour, nitrogen oxide (NOx) induced ozone and methane, and contrail-cirrus and also the merged non-CO2 algorithmic climate change functions that combine all individual contributions. These merged aCCFs can be only constructed with the technical specification of aircraft/engine parameters, i.e., NOx emission indices and flown distance per kg burnt fuel. These aircraft/engine specific values are provided within CLIMaCCF version V1.0 for a set of aggregated aircraft/engine classes (i.e. regional, single-aisle, wide-body). Moreover, CLIMaCCF allows by a user-friendly configuration setting to choose between a set of different physical climate metrics (i.e. average temperature response for pulse or future scenario emissions over the time horizons of 20, 50 or 100 years). Finally, we demonstrate the abilities of CLIMaCCF by a series of example applications.
Addressing challenges in uncertainty quantification. The case of geohazard assessments
Authors: Cardenas Ibsen Chivata , Aven Terje , Flage Roger
Published: October 2022

Abstract. By describing critical tasks in quantifying uncertainty using geohazard models, we analyse some of the challenges involved. Under the often-seen condition of very limited data and despite the availability of recently developed sophistications to parameterise models, a major challenge that remains is the constraining of the many model parameters involved. However, challenges also lie in the credibility of predictions required in the assessments, the uncertainty of input quantities, and the conditional nature of the quantification on the choices and assumptions made by analysts. Addressing these challenges calls for more insightful approaches that are yet to be developed; however, clarifications and reinterpretations of some fundamental concepts together with practical simplifications may be required first, and these are discussed in this paper. The research aims at strengthening both the foundation of geohazard risk assessments and its practice.
AutoQS v1: Automatic parameterization of QuickSampling based on training images analysis
Authors: Gravey Mathieu , Mariethoz Grégoire
Published: October 2022

Abstract. Multiple‐point geostatistics are widely used to simulate complex spatial structures based on a training image. The use of these methods relies on the possibility of finding optimal training images and parametrization of the simulation algorithms. While methods for selecting training images are available, parametrization can be cumbersome. Here, we propose finding an optimal set of parameters using only the training image as input. The difference between this and previous work that used parametrization optimization is that it does not require the definition of an objective function. It is based on the analysis of the errors that occur when filling artificially constructed patterns that have been borrowed from the training image. The main advantage of our approach is to remove the risk of overfitting an objective function, which may result in underestimating the variance or in a verbatim copy of the training image. Since it is not based on optimization, our approach finds a set of acceptable parameters in a predictable manner by using the knowledge and understanding of how the algorithms work. The technique is explored in the context of the recently developed QuickSampling algorithm, but it can be easily adapted to other pixel-based multiple-point statistics algorithms using pattern matching, such as Direct Sampling or Single Normal Equation Simulation (SNESIM).
Strategies for Conservative and Non-Conservative Monotone Remapping on the Sphere
Authors: Marsico David H. , Ullrich Paul A.
Published: October 2022

Abstract. Monotonicity is an important property of remapping operators for coupled weather and climate models. However, it is often challenging to design highly accurate operators that avoid the generation of new extrema or keep a remapped field between physically prescribed bounds. To that end, this paper explores several traditional and novel approaches for both conservative and non-conservative monotone remapping on the sphere. The accuracy and effectiveness of these algorithms are evaluated in the context of several different real and idealized fields and meshes.
BUILDING COMMUNITY RESILIENCE THROUGH GEOSPATIAL INFORMATION DASHBOARDS
Authors: Praharaj S. , Wentz E.
Published: October 2022

Abstract. This article discusses a dashboard toolkit designed at the Knowledge Exchange for Resilience at the Arizona State University to integrate and analyze multi-agency data offering many ways of visualizing big data representable, contextualizable, and intelligible to a non-expert target audience. We outline a community-driven approach to identify pressing resiliency issues and deploy dashboard tools on targeted areas for significant community benefit. Our research builds on the offerings of data science to aid community-focused decision support systems to enable evidence-based and real-time decision-making. We hypothesize that building community resilience in response to emerging challenges requires a combination of timely data at the local scale and easy-to-use decision support tools. This research particularly focuses on augmenting the capacity of communities through dashboard technologies to comprehend rapidly evolving issues and address them in a timely and efficient manner. Our work contributes to a rapidly growing research domain around geospatial data visualization technologies that are increasingly playing a vital role in the shaping of government policies, including resiliency planning and disaster response. This study argues that dashboards that are action-oriented, easy-to-use, and locally embedded within the community have much more potential to be used as a decision-support system. The findings indicate that community-based knowledge networks catalyzed and influenced by modern technologies might provide a model to negotiate the gaps between ecosystem-based and social-science-focused conceptualization of community resilience.
Real-time urban rainstorm and waterlogging disaster detection by Weibo users
Authors: Zhu Haoran , Obeng Oforiwaa Priscilla , Su Guofeng
Published: October 2022

Abstract. With the process of urbanization in China, the urban waterlogging caused by rainstorms occurs frequently and often leads to serious damage to
the natural environment, human life, and the city economy. Rapid detection of rainstorm and urban waterlogging disasters is an essential step to minimize
these losses. Weibo, a popular microblog service in China, can provide many real-time Weibo posts for rapid detection. In this paper, we propose a
method to identify microblogs with rainstorm and waterlogging information and apply them to waterlogging risk assessment. After pre-processing the
microblog texts, we evaluate the performance of clustering (k-means) and classification (support vector machine, SVM) algorithms in the
classification task. Apart from word vector features, we also introduce sentiment and publisher features for more real-time and accurate
results. Furthermore, we build a waterlogging intensity dictionary to assess the waterlogging risk from the Weibo texts and produce a risk map with
ArcGIS. To examine the efficacy of this approach, we collect Weibo data from two rainstorms and waterlogging disasters in Beijing city as examples. The results
indicate that the SVM algorithm can be applied for a real-time rainstorm and waterlogging information detection. Compared to official-authentication and personal-certification users, the microblogs posted by general users can better indicate the intensity and timing of rainstorms. The
location of waterlogging points is consistent with the risk assessment results, which proves our proposed risk assessment method can be used as a
reference for timely emergency response.
What distinguishes 100-year precipitation extremes over Central European river catchments from more moderate extreme events?
Authors: Ruff Florian , Pfahl Stephan
Published: October 2022

Abstract. Historical extreme flooding events in Central European river catchments caused high socioeconomic impacts. Previous studies analysed single events in detail but did not focus on a robust analysis of the underlying extreme precipitation events in general as historical events are too rare for a robust assessment of their generic dynamical causes. This study tries to fill this gap by analysing a set of realistic daily 100-year large-scale precipitation events over five major European river catchments with the help of operational ensemble prediction data from the ECMWF. The dynamical conditions during such extreme events are investigated and compared to those of more moderate extreme events (20- to 50-year). 100-year precipitation events are generally associated with an upper-level cut-off low over Central Europe in combination with a surface cyclone southeast of the specific river catchment. The 24 hours before the event are decisive for the exact location of this surface cyclone, depending on the location and velocity of the upper-level low over Western Europe. The difference between 100-year and more moderate extreme events vary from catchment to catchment. Dynamical mechanisms such as an intensified upper-level cut-off low and surface cyclone are the main drivers distinguishing 100-year events in the Oder and Danube catchments, whereas thermodynamic mechanisms such as a higher moisture supply in the lower troposphere east of the specific river catchment are more relevant in the Elbe and Rhine catchments. For the Weser/Ems catchment, differences appear in both dynamical and thermodynamic mechanisms.

Published: October 2022

Conductive hydrogels have great application and development value in the field of functional materials including flexible wearable devices, electronic skin and health detectors. Herein, chitosan (CS) was firstly modified with 3,4-dihydroxybenzaldehyde and 2,3,4-trihydroxybenzaldehyde, respectively, through the Schiff base reaction and NaBH3CN reduction, and the resulting products (CCS and PCS) with improved water solubility were then used as the cross-linking agents for polyvinyl alcohol (PVA) to fabricate the corresponding CCS/PVA and PCS/PVA composite hydrogels through the freezing-thawing method. AlCl3 was further introduced into the two composite systems to give the hydrogels good conductivity. As flexible strain sensors, both CCS/PVA/AlCl3 and PCS/PVA/AlCl3 hydrogels could monitor human movements such as finger bending, wrist rotation, elbow bending, foot rotation and nodding. In addition, the conductive hydrogels can also respond regularly to small facial movements such as mouth opening-closing cycle and frowning. In general, the present CCS/PVA/AlCl3 and PCS/PVA/AlCl3 conductive hydrogels are expected to have good application prospect in smart wearable devices and other functional fields.
Engineering approaches for modelling urban heat stress under a comfort and health perspective
Authors: Costanzo Vincenzo
Published: October 2022

Today, more than 50% of the world population lives in cities, with a prospect of increasing to 70% by 2050. These percentages have already been exceeded in Europe, in particular in the Mediterranean Area, where the urban population rate is of about 68%. On the other hand, also the ageing process of the population is increasing at a worrying rate, and this process has a direct impact on health and vulnerability conditions in the urban context. However, only recently it has been understood how the physical environment of cities becomes a determining factor for the well-being of citizens, especially in light of current climate change and consequent increase of health risks.
This presentation aims at showing how the complex physical processes involved in determining the so called Urban Heat Stress, i.e. the high temperatures achieved within urban settlements, can be modelled with engineering-based methods. Such approaches could be used to predict which urban areas are more prone to heat stress, to advise the population of likely health risks on certain very hot days and also to plan suitable mitigation interventions.
On Aesthetics in Chinese Calligraphy of Qin, Han, Wei and Jin Dynasties

Different historical periods in China had different artistic and cultural pursuits, as did calligraphy. Calligraphers of all ages practiced diligently, diligently pursuing a higher level of calligraphy art training, I can lament that this time in china is different from the past, in today's increasingly advanced science and technology, people have long forgotten to write this skill. Calligraphy has also sadly lost her dazzling glory of the times, there are now few calligraphy practitioners in the crowd. Therefore, with the passing of a group of modern calligraphy, there is no calligraphy in China for a hundred years to lead the times, it is really lamentable. In order to find the aesthetics in calligraphy, I had to start with ancient Chinese calligraphy. This paper will discuss the aesthetic features of Chinese calligraphy in Qin, Han, Wei and Jin dynasties.

The ideology of a text can be seen in a story, and one can see the message behind a story, even though the story is a popular one that can be reused in many versions. Theories within the framework of media adaptation can be used to interpret changing ideologies behind a text that transformed alongside developing issues, even if the story is only told in a different medium. This is visible on the French popular folktale, La Belle et La BeÌ‚te (Beauty and the Beast), that was adapted into animation film by Walt Disney Pictures (1991), and the live action French film by Christophe Gans (2014). The battle of ideologies can be seen through the reconstruction of Belleâ€™s story by Walt Disney Pictures, through Belleâ€™s leitmotif, and Christophe Gansâ€™s deconstruction that he did by removing, changing, or adding narrative and cinematographic materials that were present in the Disney version. Ideologi teks dapat tampak di sebuah karya agar mampu ditemukan pesan yang ingin disampaikan walaupun ceritanya merupakan sebuah cerita populer yang dapat dibuat berulang kali dalam berbagai versi. Kajian alih wahana untuk membaca ideologi teks yang berbeda dapat dikaitkan dengan isu yang sedang berkembang di zamannya, walaupun dengan cerita yang diangkat dari sumber yang sama. Hal ini terjadi pada dongeng populer Prancis, La Belle et La BeÌ‚te (Beauty and the Beast) yang dialihwahanakan menjadi animasi oleh Walt Disney Pictures tahun 1991 dan film Prancis versi live action karya Christophe Gans tahun 2014. Pertarungan ideologi terlihat dari rekonstruksi kisah Belle oleh Walt Disney Pictures melalui leitmotif karakter Belle dan dekonstruksi yang dilakukan Christophe Gans dengan menghilangkan, mengubah, atau menambahkan materi naratif dan sinematografis yang sudah dibangun di versi animasi Disney.
Representation of Muslim Women in Manga Satoko & Nada

Published: October 2022

Since the beginning of the 21stÂ century, the mass media has been inclined towards constructing a negative image of Islam, which is internalized by the societies in countries where Moslems are in the minority, including Japan. Modern Japanese society is very dependent on the mass media for quick and concise information. The image of Islam internalized by the Japanese society is the one associated with terrorism and backwardness. This paper presents a different representation of Islam as reflected in a Japanese mangaÂ Satoko & NadaÂ which focuses on the friendship between a Japanese girl Satoko and an Arab girl Nada in the United States. Visual and verbal analysis on the manga reveals an uncommon image of Moslem women which is not inclined towards excessive self-limitation. The manga shows that Moslem women really have a degree of freedom to express themselves, albeit with some limitation. Besides that, it also features open-minded Moslem women who are not hesitant to welcome modernization. Those characteristics are very different from the popular beliefs about Moslem women as constructed by mainstream mass media. As one of Japanese popular media, mangaÂ Satoko & NadaÂ serves as a counter narrative by offering a different image of Moslem women as never shown in common mass media.Â Mulai dari dekade 2000-an, Media massa mengonstruksi citra Islam yang cenderung negatif dan telah terinternalisasi pada masyarakat di negara-negara non-mayoritas Islam, termasuk Jepang. Masyarakat Jepang modern sangat tergantung pada media massa untuk mendapatkan informasi dengan ringkas dan cepat. Imaji Islam yang terinternalisasi di dalam masyarakat Jepang pun terasosiasi pada terorisme dan keterbelakangan. Dalam makalah ini akan dipaparkan representasi muslim yang berbeda dalam manga Jepang berjudul Satoko&Nada yang menceritakan persahabatan Satoko, gadis yang berasal dari Jepang dan Nada, gadis yang berasal dari Arab di Amerika Serikat. Dari analisis visual dan verbal terlihat konstruksi identitas wanita muslim yang tidak sepenuhnya tertutup. Diperlihatkan bahwa wanita muslim di dalam Satoko&Nada memiliki kebebasan untuk mengekspresikan dirinya walaupun terbatas. Selain itu diperlihatkan pula wanita muslim yang memiliki pemikiran terbuka dan mengikuti arus modernisasi. Karakteristik-karakteristik tersebut sangat berlawanan dengan popular belief mengenai wanita muslim yang telah dikonstruksi dalam media massa. Manga Satoko&Nada sebagai salah satu dari media populer Jepang menyampaikan wacana tandingan mengenai wanita muslim yang tidak pernah terlihat di dalam media massa.
