Determination of the chemical equator from GEOS-Chem model simulation: a focus on the tropical western Pacific region
Authors: Sun Xiaoyu , Palm Mathias , Müller Katrin , Hachmeister Jonas , Notholt Justus
Published: June 2023

Abstract. The tropical western Pacific (TWP) plays an important role in global stratosphere–troposphere exchange and is an active region of the interhemispheric transport (IHT). Common indicators for transport between the hemispheres like the tropical rain belt are too broad or lack precision in the TWP. In this paper, we provide a method to determine the atmospheric chemical equator (CE), which is a boundary for air mass transport between the two hemispheres in the tropics. This method used the model output from an artificial passive tracer simulated by the chemical transport model GEOS-Chem in the troposphere. We investigated the movement of the CE in the tropics, which indicates the migration of atmospheric circulation systems and air mass origins. Our results show the CE on different timescales, suggesting that the different features of the IHT in different regions are highly related to the variation in the circulation systems. We compared the CE with the tropical wind fields, indicating that the region of IHT does not coincide with the convergence of the 10 m wind fields in the tropical land sectors and the TWP region. We compared the CE with the atmospheric composition such as satellite data of CH4 and model simulation of sulfur hexafluoride (SF6). The results show that the CE and north–south gradient of CH4 in the Indian Ocean in January are well consistent with each other, which indicates the CE has good potential to estimate the IHT inferred by observations. We discussed the vertical extent and the meridional extent of the IHT. We find that the vertical structure above 2 km has a slight northern tilt in the Northern Hemisphere (NH) winter season and a southern tilt in the NH summer, meaning the seasonality of the migration of the CE at the lower altitude is larger than that at the higher altitude. The meridional extent of the CE indicates a narrow transition zone where IHT happens throughout the year. We find that the meridional extent above South America is larger compared to other regions. The distribution of the land–sea contrast plays an important role in the meridional extent of IHT. We focus on the TWP region and further compared the tropical rain belt with the CE. There is a broad region of high precipitation occurring in the TWP region, and it is difficult to determine the IHT by the rain belt. In the NH winter, the CE is not consistent with the tropical rain belt in the TWP but is confined to the southern branch of the peak of the rain belt. For the other seasons, both indicators of IHT agree.

Abstract. Litter decomposition is an important factor affecting local and global C cycles. It is known that decomposition through soil microbial activity in ecosystems is mainly influenced by soil type and climatic conditions. However, for agroecosystems, there remains a need for a better understanding how management practices influence litter decomposition. This study examined the effect of different management practices on decomposition at 29 sites with long-term (mean duration of 38 years) field experiments (LTEs) using the Tea Bag Index (TBI) protocol with standard litter (Rooibos and Green tea) developed by Keuskamp et al. (2013). The objective was to determine if the TBI decomposition rate (k) and stabilization factor (S) are sensitive enough to detect differences in litter decomposition between management practices, and how they interact with edaphic factors, crop type and local climatic conditions. Tea bags were buried and collected after ~60 and 90 days in 16 Austrian and 13 Swedish sites. The treatments at Austrian LTEs focused on mineral and organic fertilization, tillage systems and crop residues management, whereas the Swedish LTEs addressed cropping systems, mineral fertilization and tillage systems. The results showed that in Austria, decomposition differed more between sites than between treatments for the same experiment category. Incorporation of crop residues and high N fertilization increased k. Minimum tillage had significantly higher k compared to reduced and conventional tillage. In Sweden, litter decomposition differed more between treatments than between sites. Fertilized plots showed higher S than non-fertilized and high N fertilization had the highest k. Growing spring cereal lead to higher k than forage. Random Forest regressions showed that k and S were mainly governed by climatic conditions, which explained more than 70 % of their variation. However, under similar climatic conditions, management practices strongly influenced decomposition dynamics. Thus, the TBI approach may be suitable to apply in a more large-scale network on LTEs for evaluating decomposition dynamics more precisely.

Published: June 2023

Abstract. Shallow and coastal waters are often rich in nutrients (eutrophic) and biologically productive, turbid from runoff, and located where the atmosphere above can be more aerosol-laden than over open ocean waters due to proximity to aerosol sources on land. Although the NASA Earth Observing System’s Multi-angle Imaging SpectroRadiometer (MISR) on board the Terra satellite has been monitoring global aerosols for over 23 years, the current operational retrieval algorithm (V23) is not applied over waters less than 50 m in depth or within 5 km of land, designated as "shallow water." This is due to the simplicity of the Dark Water algorithm, applied operationally over deep waters, which assumes the surface is essentially black in the primarily-used red and near-infrared spectral bands. In this work, we describe the implementation and validation of a "Shallow Water" aerosol retrieval algorithm for MISR, which takes advantage of all four available spectral bands and includes a Lambertian surface reflectivity term to account for water-leaving radiance. This algorithm compares well to independent, surface-based observations and demonstrates better performance over shallow waters than the operational Dark Water retrieval algorithm. Globally, aerosol retrievals over shallow waters increase the total number of MISR over-water measurements by more than 7 %, including new retrievals made over some of the most biologically productive parts of the ocean.

Authors: Tang Wenjun , He Junmei , Qi Jingwen , Yang Kun
Published: June 2023

Abstract. The lack of long-term and high-quality solar radiation data has been an obstacle for scientific and industrial fields. In this study, a dense station-based long- term and high-accuracy dataset of daily surface solar radiation was developed using two surface radiation models. One is the model developed by Yang et al. (2006) for global radiation estimation, and the other is the model developed by Tang et al. (2018) for direct radiation estimation. The main inputs for the development of the dataset are surface pressure, air temperature, relative humidity, horizontal visibility, and sunshine duration, which are the routine meteorological variables observed at the 2743 China Meteorological Administration (CMA) weather stations. Validation against in-situ observations and comparisons with two satellite-based radiation products show that our station-based radiation dataset clearly outperforms the satellite-based radiation products at both daily and monthly scales. In addition, our dataset is available for more than 60 years and includes three radiation components of global, direct and diffuse radiation, which is not possible with satellite products. This station-based radiation dataset will contribute to the climate change research and solar energy engineering applications in the future.
THE EVALUATION OF STRUCTURE-FROM-MOTION WORKFLOW WITH THE TLS SYNTHETIC IMAGES SIMULATOR – THE CULTURAL HERITAGE APPROACH

Published: June 2023

Abstract. Modern measurement technologies such as Terrestrial Laser Scanning or combined Structure-from-Motion with Multi-View Stereo are commonly utilised to monitor, preserve and document cultural heritage objects and sites. For this reason, it is essential to know the capabilities and limitations of the sensor used, the data processing methods, and in particular, the orientation of the images. However, these algorithms tackle different errors and have different effects on the final accuracy of images orientation. For this reason, it is essential to know how the algorithms implemented in the Structure-from-Motion approach work. Due to the impossibility of obtaining this information for commercial solutions, it is necessary to use synthetic data to assess the quality of the SfM process. Therefore, this article aims to present the method of evaluation of SfM approach implemented in commercial Agisoft Metashape and COLLMAP open-source software based on the synthetic data generated from TLS point clouds of three different Cultural Heritage sites. In addition, obtained results were compared with the author's SfM approach based on BRISK, FAST, CenSurE, SIFT and SURF (and its Affine detectors equivalents) detector implemented (Fig. 1) and Learned-based -feature extraction approach SuperGlue and LoFTR. The second aim of this research is to propose an application to automatically generate scalable benchmark based on point clouds or 3D models of cultural heritage objects.

Published: June 2023

Abstract. Conventional or learning-based 3D reconstruction methods from images have clearly shown their potential for 3D heritage documentation. Nevertheless, Neural Radiance Field (NeRF) approaches are recently revolutionising the way a scene can be rendered or reconstructed in 3D from a set of oriented images. Therefore the paper wants to review some of the last NeRF methods applied to various cultural heritage datasets collected with smartphone videos, touristic approaches or reflex cameras. Firstly several NeRF methods are evaluated. It turned out that Instant-NGP and Nerfacto methods achieved the best outcomes, outperforming all other methods significantly. Successively qualitative and quantitative analyses are performed on various datasets, revealing the good performances of NeRF methods, in particular for areas with uniform texture or shining surfaces, as well as for small datasets of lost artefacts. This is for sure opening new frontiers for 3D documentation, visualization and communication purposes of digital heritage.

Published: June 2023

Abstract. The conservation of cultural heritage can be affected by different changes in temperature and humidity within architectural spaces, so energy performance and interior microclimate of historic buildings require adaptation to new maintenance and prevention studies. The search for these new investigations brings cultural heritage closer to new digital technologies such as Historic Building Information Modelling (HBIM). In this work, a new interdisciplinary methodology is developed between energy operators and BIM operators, so that a new framework is created to monitor energy parameters through intelligent sensors that measure temperature and humidity in the fully interoperable and semantically enriched 3D model itself. The study's commitment involves solving the interoperability workflow between sensors and the BIM platform, taking advantage of this new interconnectivity. For the study, a methodology applied to the Church of the Sacred Heart of Jesus in Seville was carried out, where from a survey through a georeferenced terrestrial laser scanner with topographic equipment, it is modelled from the point cloud, incorporating the sensors in the HBIM Project. In the workflow, it has been shown that the integration of microclimate data inside churches can be managed directly in the environment of an HBIM-based model and transfer a reverse flow in the process.
HBIM MODELLING FOR THE ARCHITECTURAL VALORISATION VIA A MAINTENANCE DIGITAL ECO-SYSTEM

Published: June 2023

Abstract. The present contribution falls within the framework of the actions envisaged by the "SMART Bethlehem – Sustainable Management And Renewal of Technology in the City of Bethlehem" (2022 – ongoing) research project, scientifically coordinated by the University of Pavia and co-founded by the Italian Agency for Cooperation and Development (AICS). Among the main objectives of the cooperation project is the sustainable urban and territorial development of the Bethlehem area by means of multi-scalar activities, mainly focusing on refurbishment and energy optimisation of a few relevant municipality buildings. A test case implementation of the HBIM methodology was then carried out on the Peace Center, an iconic building facing the "Manger Square" in close proximity to the "Nativity Church", aiming to validate the proposed systematisation of a scan-to-BIM approach focused on the development of an optimised data repository for the planned operation and maintenance activities. An ECO-Systemic workflow is presented, organised in five recursive steps. Starting from a SLAM-TLS integrated digital survey (3DS), the federated sub-models that comprise the overall project are geo-referenced (GEO) within a shared coordinate system (FSC) environment, thereby providing the basis for the subsequent architectural modelling of the built asset (ARC) and the associated enhancement of the level of information (LOI).

Published: June 2023

Abstract. In cultural heritage, three-dimensional documentation of historic buildings is fundamental for conservation and valorisation projects. In recent years, the consolidated tools and methods: Terrestrial Laser Scanning (TLS) and close-range photogrammetry, have been joined by portable Mobile Mapping Systems (MMSs), which can offer significant advantages in terms of speed of survey operations at the price of reduced accuracy. The reduction of survey times and, therefore, costs makes the application of MMS techniques ideal for the preliminary stages of analysis of historical artifacts, when a rapid survey is indispensable for estimating the costs of conservation interventions.In this paper, we present a methodology for the expeditious survey of historic buildings and the surrounding urban fabric that is based on the use of an MMS and an Unmanned Aerial Vehicle (UAV). The MMS is the Gexcel Heron MS Twin color. It was used to survey two architecture of interest and the urban context surrounding them from the ground level. The UAV is the DJI Mini 2, used to integrate the terrestrial survey by acquiring the buildings' roofs. The case study presented in the paper is the survey of San Clemente and San Zeno al Foro churches, two historic churches in the city centre of Brescia (Italy).The result are a complete point cloud of the two buildings and a metric virtual tour of all spaces. These results were made available to the architects through the Cintoo web platform to plan future activities.
CENSUS OF ABANDONED BUILT HERITAGE ASSETS: THE IMPORTANCE OF DEFINING SHARED METHODOLOGIES AND ONTOLOGIES

Published: June 2023

Abstract. The paper shows the studies carried out within the framework of two research agreements for the census of abandoned enlisted assets owned by public bodies in the Provinces of Piacenza, Parma and Reggio Emilia, stipulated with the respective Heritage Departments. The purpose of this research is to increase the cognitive framework of cultural assets in a state of abandonment, and then to transfer the results to the dedicated WebGIS platform, with the aim of identifying the ones which are most in need of a conservation and reuse intervention, in order to return them back to their community. Afterwards, as a result of the cataloguing carried out, it was possible to make some critical considerations and statistical reworkings of the collected data. The data analysis, performed through the design of a GIS database, finds out a higher frequency of abandonment for some specific building types and with recurring locations. The research also highlights, once again, the importance of defining common ontologies, which are essential for statistical data processing and interoperability between different existing databases.
The potential of open-access data for flood estimations: uncovering inundation hotspots in Ho Chi Minh City, Vietnam, through a normalized flood severity index
Authors: Scheiber Leon , Hoballah Jalloul Mazen , Jordan Christian , Visscher Jan , Nguyen Hong Quan , Schlurmann Torsten
Published: June 2023

Abstract. Hydro-numerical models are increasingly important to
determine the adequacy and evaluate the effectiveness of potential flood
protection measures. However, a significant obstacle in setting up
hydro-numerical and associated flood damage models is the tedious and
oftentimes prohibitively costly process of acquiring reliable input data,
which particularly applies to coastal megacities in developing countries and
emerging economies. To help alleviate this problem, this paper explores the
usability and reliability of flood models built on open-access data in
regions where highly resolved (geo)data are either unavailable or difficult
to access yet where knowledge about elements at risk is crucial for
mitigation planning. The example of Ho Chi Minh City, Vietnam, is taken to
describe a comprehensive but generic methodology for obtaining, processing
and applying the required open-access data. The overarching goal of this
study is to produce preliminary flood hazard maps that provide first insights
into potential flooding hotspots demanding closer attention in subsequent,
more detailed risk analyses. As a key novelty, a normalized flood severity
index (INFS), which combines flood depth and duration, is proposed to
deliver key information in a preliminary flood hazard assessment. This index
serves as an indicator that further narrows down the focus to areas where
flood hazard is significant. Our approach is validated by a comparison with
more than 300 flood samples locally observed during three heavy-rain events
in 2010 and 2012 which correspond to INFS-based inundation hotspots in
over 73 % of all cases. These findings corroborate the high potential of
open-access data in hydro-numerical modeling and the robustness of the newly
introduced flood severity index, which may significantly enhance the
interpretation and trustworthiness of risk assessments in the future. The
proposed approach and developed indicators are generic and may be replicated
and adopted in other coastal megacities around the globe.
General considerations to experimental research on ocean alkalinity enhancement
Authors: Dupont Sam , Metian Marc
Published: June 2023

Abstract. The abundant literature on ocean acidification is documenting the impact of changes in the carbonate chemistry on marine life from genes to ecosystems. A vast majority of the experimental work was performed by manipulating the concentration of carbon dioxide in seawater under constant alkalinity (TA) to simulate near-future ocean acidification. Understanding the impact of changes in alkalinity on marine species and ecosystem is less understood. In the context of ocean alkalinity enhancement (OAE), it is critical to resolve such impacts, alone or in combination with other key trace elements to be co-released during implementation, to ensure that any field manipulation does not translate into damaging biological effects. As for other environmental drivers, this will require a biological understanding across all the levels of biological organizations from species to ecosystems, over relevant time exposure considering the method of deployment and considering factors such as local adaptation. Such complex questions cannot be resolved using a single approach and a combination of monitoring, modeling, laboratory, natural, and field experiments will be required. This chapter summarizes some key general considerations for experimental design as well as compare strengths and weaknesses of the different approaches. We will also consider best-practices relevant to OAE such as the need to properly monitor and consider the addition of trace elements and by-products as well as the potential interactions with other naturally occurring drivers.
Analysis and multi-objective optimisation of model-based wind turbine controllers

Published: June 2023

Abstract. The combined wind speed estimator and tip-speed ratio (WSE-TSR) tracking wind turbine control scheme has seen recent and increased traction from the wind industry. The modern control scheme provides a flexible trade-off between power and load objectives. On the other hand, the Kω2 controller is often used based on its simplicity and steady-state optimality and is taken as a baseline here. This paper investigates the potential benefits of the WSE-TSR tracking controller compared to the baseline by analysis through a frequency-domain framework and by optimal calibration through a systematic procedure. A multi-objective optimisation problem is formulated for calibration with the conflicting objectives of power maximisation and torque fluctuations minimisation. The optimisation problem is solved by approximating the Pareto front based on the set of optimal solutions found by an explorative search. The Pareto fronts obtained for calibration of the baseline and for increasing fidelities of the WSE-TSR tracking controller show that no optimal solution exists, translating into increased power capture with respect to the baseline Kω2 controller. The frequency-domain analysis, however, shows increased control bandwidth for tip-speed ratio reference tracking for the solution leading to power maximisation. If the objective is to reduce the torque variance, the controller bandwidth decreases with a mild penalty on the energy yield. High-fidelity simulations on the NREL 5MW reference turbine confirm this trend, proving that, if properly calibrated, the WSE-TSR tracking controller obtains approximately the same generated power of the baseline while reducing torque actuation effort.

Современный мир со всеми его стремительными изменениями и также с наблюдаемым иногда «смещением» ценностных ориентиров требует осмысления исторического наследия прошлого и сохранения лучших традиций и обычаев, выраженных в тех ценностях, которые передаются из поколения в поколение. Увидеть, объективно оценить, понять и конструировать будущее человека и целой страны можно, если мы чаще будем обращаться к прошлому, пытаясь восстановить достоверные научные знания, а также законы развития общества, которые будут затем переданы потомкам. При этом важно основываться на опыте и достижениях предшествующих поколений, вводить в научный оборот имеющиеся архивные материалы, касающиеся как жизни отдельной личности, так и истории народа, государства. Для осмысления прошлого в истории науки существуют различные формы изданий, в том числе энциклопедии, монографии, тексты различных жанров, репрезентирующие опыт наших предков и определённые закономерности в развитии историко-культурной парадигмы народа.

В этой статье мы сообщаем об экспериментах, в которых методы рассеяния света использовались для изучения динамических процессов на поверхности растущих кристаллов. В этой статье мы хотим передать два сообщения: 1. Методы рассеяния света полезны для характеристика процессов роста. Мы хотим побудить производителей кристаллов использовать эти методы. 2. Будут представлены экспериментальные результаты, которые показывают, что поверхность растущего кристалла не является острой и что кристаллизация не является одностадийным процессом. Имеются свидетельства наличия слоя промежуточной фазы на поверхности растущих кристаллов. Этого слоя может быть несколько, очень толстых. В этом слое наблюдаются длительные непрерывные колебания. Скорость затухания этих колебаний в 106 раз ниже, чем скорость затухания колебаний плотности в объемном расплаве. Эта статья организована следующим образом: Введение в квазиупругое рассеяние света дано в разделе 2. В разделе 3 мы покажем, как этот метод может быть применен к задачам роста кристаллов и как можно измерить параметры, имеющие отношение к росту кристаллов. Акцент будет сделан на изучении динамических процессов, которые не могут быть изучены другими методами.

EFFECTS OF HOMOGENEOUS AND HETEROGENEOUS REACTIONS ON THE THERMALLY STRATIFIED WATER-BASED NANOFLUID STREAMING ABOVE AN EXTENDING SURFACE
Authors: BORAH RUPJYOTI , Dey Debasish , Hazarika Madhurya
Published: June 2023

The effect of homogeneous and heterogeneous reactions, as well as second-order velocity slip, on the magnetic influenced flow of nanofluid (Cu-water and MgO-water) passes above an extending surface has been examined. To alter the nature of leading equations of this problem, a new set of dimensionless variables have been employed. The resulting equations with the corresponding surface restrictions are solved using the Runge-Kutta-Fehlberg technique (RKF45) by developing a code in Maple-18. The outcomes of this investigation are presented in terms of pictorial mode with the effects of different novel flow parameters. Also, numerical values of physical quantities that are associated with this problem are set in terms of tabular mode. It is perceived that increasing the number of solid particles, the thermal and mass fractions of the nanofluid behave as an enhancing function, whereas the motion of the nanofluid is a decreasing function.

Published: June 2023

This study was conducted to optimize the hydrodistillation process of Mentha spicata L. essential oil using the response surface methodology. The optimal values of operating parameters (independent variables) such as extraction time (100–240 min) and water volume to plant mass ratio (0.055–0.120) were investigated using a central composite design, which led to only 13 experiments. The response variables were selected the highest essential oil yield, and also the carvone ratio, which is the main component of the essential oil. The experimental data was fitted to a linear model for essential oil yield and a modified quadratic model for the carvone ratio. The hydrodistillation time and water volume to plant mass ratio have significant effects (p<0.05) on the both the essential oil yield and the carvone ratio. The optimal conditions were identified as 145.7 min of extraction time and a 0.105 ml/g water volume to plant mass ratio by the 3D response surface and the contour plots derived from the models. At these predicted conditions, the essential oil yield and carvone ratio were calculated to be 1.383% and 28.541%, respectively. The findings indicate that the response surface approach can be used successfully in the hydrodistillation of Mentha spicata L.

Published: June 2023

Consequence analysis can timely predict the occurrence of potential chemical safety accidents, but is time-consuming and inaccurate when using a manual and qualitative mode. A safety con-sequence analysis method based on dynamic simulation is proposed for chemical processes in this paper. The dynamic simulation system of chemical process is composed of complete thermodynamic model and general unit model to quantitatively describe the dynamic change of chemical process parameters. Combined with fault tree analysis, the accident model is designed prior to forecasting safety consequences by computational fluid dynamics. This method was applied to acetylene production process. A dynamic simulation system was designed to calculate the pressure and concentration of acetylene leakage gas and analyze the parameters affecting the diffusion of acetylene gas. The results show that this method can obtain the quantitative change of acetylene concentration with time at different locations around acetylene generator, which is convenient for accurate and dynamic analysis of process safety consequence.

AN INTELLIGENT NETWORK SLICING FRAMEWORK FOR DYNAMIC RESOURCE SHARING IN MULTI-ACCESS EDGE COMPUTING ENABLED NETWORKS
Authors: Munir Rizwan , WEI YIFEI , TONG LEI
Published: June 2023

Dynamic resource sharing in multi-access edge computing (MEC) enabled networks has gained tremendous interest in the recent past, paving the way for the realization of beyond fifth generation (B5G) communication networks. To enable efficient and dynamic resource sharing, Network Slicing has appeared as a promising solution, virtualizing the network resources in the form of multiple slices employed by the end-users requiring strict latency, proximate computations, and storage demands. In literature, network slicing is primarily studied in the context of communication resource slicing, and little research has been devoted to jointly slicing communication, energy, and MEC resources. In this paper, we, therefore, proposed a joint network-slicing framework that considers 1) communication resources, 2) compute resources, 3) storage resources, and 4) energy resources, and intelligently and dynamically shares the resources between different slices, aiming to improve tenants' overall utility. To this end, we formulated a utility maximization problem as Markov-chain Decision Process. We utilized a tenant's manager that employs a deep reinforcement learning technique named "deep deterministic policy gradient" to enable dynamic resource sharing. Simulation results reveal the effectiveness of the proposed scheme.

In food and biological materials, most methods used to determine the effective moisture diffusivity do not provide reliable results. In this work, an experimental approach to determine the instantaneous diffusion coefficient of pumpkin slices during drying process was used. We use the inverse method by combining the Levenberg-Marquardt optimization technique with analytical solutions of Fick's second law of dif-fusion. A series of drying kinetics experiments are performed followed by the analytical identification of moisture diffusivity. All experimental runs were carried out according to response surface based on central composite design, and the results obtained were validated
