Improved Arctic Melt Pond Fraction Estimation Using Sentinel-2 Imagery
Authors: Sivaraj Kavya , Solander Kurt , Abolt Charles , Hunke Elizabeth
Published: November 2024

Abstract. Melt ponds play a vital role in determining the Arctic energy budget by accelerating the rate of sea ice loss aided by their lower albedo. Therefore, an accurate long-term estimate of Arctic Melt Pond Fraction (MPF) is necessary to forecast summer Arctic ice-free conditions. Earth Observation (EO) satellite systems provide ideal tools to monitor the evolution of melt ponds, both spatially and temporally, in near-real time. However, the MPF estimates from these studies are affected by the presence of small, fragmented ice floes called brash ice, and submerged ice. An improved workflow is necessary to remove the effects of the aforementioned sea ice features from the MPF estimate. Here, we estimate MPF using Sentinel-2 imagery, by coupling a Random Forest (RF) model with mathematical morphological algorithms – morphological dilation and morphological reconstruction – which improves the estimate of MPF by reducing misclassifications from nilas, submerged, and brash ice. Further, we present an inter-seasonal MPF time-series from 2018 to 2021 and show that employing morphological operations after the RF reduces the mean MPF by greater than 40 %. Our results show that the MPF exhibited considerable intra- and inter-seasonal variations, with the maximum MPF reaching as high as 57 %.

Published: November 2024

Abstract. Accurate precipitation data are essential for understanding the Arctic climate, yet estimates from satellite, re-analysis, or climate models remain uncertain. Ground-based observations, which are sparse in the Arctic, are needed for a better understanding of precipitation processes and, as reference points, can help to characterize uncertainties and improve precipitation estimates. We present extended precipitation measurements at the Arctic research station AWIPEV in Ny-Ålesund, Svalbard, consisting of a Pluvio precipitation gauge, a Parsivel disdrometer, and a micro rain radar. Analyzing four years of data (August 2017–December 2021), we characterized precipitation by amount, type, and frequency and also focused on extreme events. Monthly precipitation at Ny-Ålesund varied widely, from 1 to 155 mm. We also associated the contribution of weather systems, i.e., of atmospheric rivers (ARs), cyclones, and fronts, to precipitation amount. Though ARs (separated or co-located with other weather systems) occur only 8 % of the time at Ny-Ålesund, 43 % of the total precipitation amount is measured during these events and 22 % when only ARs are present. Cyclones contributed 40 % (21 %) of the total precipitation amount if all (separated) cyclone events are considered. Extreme precipitation events were largely associated with ARs, i.e. in 11 out of 12 cases. Determining precipitation occurrence depends very much on the observation method and the temporal resolution, from 1 % (Pluvio at 1-minute resolution) to 21 % (micro rain radar) and increased to 38 % with daily resolved Pluvio data. Identifying precipitation type solely through Parsivel remains challenging, and a more detailed evaluation using in-situ methods is needed.

Published: November 2024

Abstract. A comprehensive, high-resolution hydrodynamic operational service using XBeach model is presented and tested for three urban beaches in Barcelona, NW Mediterranean Sea. The operational architecture is based on Python scripts combined with task automation tools, ensuring a user-friendly system implemented on a standard desktop computer. Hydrodynamic validation of the model is carried out using data gathered during a field campaign in 2022, when a high-intensity storm occurred, resulting in a root mean square error of around 0.4 m and a skill score assessment index of 0.82. Flooding predictions were validated using videometry systems, yielding satisfactory Euclidean distances less than 5 m for storms close to the topobathymetry collection. For storms occurring years earlier, the distances ranged between 7–15 m, underscoring the need for regular topobathymetry updates to maintain forecasting accuracy. The operational system is designed to provide early-warning coastal flooding at three-days horizon. The service provides a warning system with a specific categorisation of the event, enabling the end-users to prepare for a possible flooding. The outcome assists in decision-making of such events by utilizing the operational system. The presented methodology is easily adaptable and replicable to meet user requirements or to be applied in other areas of interest.
Application of quality-controlled sea level height observation at the central East China Sea: Assessment of sea level rise

Published: November 2024

Abstract. This study presents the state-of-the-art quality control (QC) process for sea level height (SLH) time series observed at the Ieodo Ocean Research Station (I-ROS) in the central East China Sea, a unique in-situ measurement in the open sea for over two decades with a 10-minute interval. The newly developed QC procedure called the Temporally And Locally Optimized Detection (TALOD) method has two notable differences in characteristics from the typical ones: 1) spatiotemporally optimized local range check based on the high-resolution tidal prediction model TPXO9, 2) considering the occurrence rate of a stuck value over a specific period. Besides, the TALOD adopts an extreme event flag (EEF) system to provide SLH characteristics during extreme weather. A comparison with the typical QC process, satellite altimetry, and reanalysis products demonstrates that the TALOD method can provide reliable SLH time series with few misclassifications. Through budget analysis, it was determined that the sea level rise at I-ORS is primarily caused by the barystatic effect, and the trend differences between observations, satellite, and physical processes are related to vertical land motion. It was confirmed through GNSS that ground subsidence of -0.89±0.47 mm/yr is occurring at I-ORS. As a representative of the East China Sea, this qualified SLH time series makes dynamics research possible spanning from a few hours of nonlinear waves to a decadal trend, along with simultaneously observed environmental variables from the air-sea monitoring system in the research station. This TALOD QC method is designed for SLH observations in the open ocean, but it can be generally applied to SLH data from tidal gauge stations in the coastal region.
Parameter Sensitivity Study of Energy Transfer Between Mesoscale Eddies and Wind-Induced Near-Inertial Oscillations
Authors: Zhang Yu , Gu Jintao , Chen Shengli , Hu Jianyu , Sheng Jinyu , Xing Jiuxing
Published: November 2024

Abstract. Analyses of current observations and numerical simulations at two moorings in the northern South China Sea reveal the transfer of near-inertial energy between the background currents associated with mesoscale eddies and near-inertial currents (NICs). A series of numerical experiments are conducted to determine important parameters affecting the energy transfer between idealized mesoscale eddies and NICs generated by rotating winds. Speeds of NICs transferred by both cyclonic and anticyclonic mesoscale eddies increase linearly with the wind stress and eddy strength. The transferred NICs in anticyclonic eddies have current amplitudes of about six times larger than in cyclonic eddies. The translation speed of the mesoscale eddy and the wind rotation frequency also affect the conversion of NICs. The energy transfer rate is elevated with the increase of the positive Okubo-Weiss parameter. A simple theoretical analysis is conducted to verify our findings based on numerical results. Analytical solutions confirm the evident asymmetry of the energy transfer between anticyclonic and cyclonic eddies, and demonstrate quantitatively the relationship between the wind stress and the near-inertial energy transferred by mesoscale eddies.

Authors: Bromwich David , Wang Sheng-Hung , Zou Xun , Ensign Alexandra
Published: November 2024

Abstract. An updated near-surface temperature reconstruction for the Antarctic continent is presented for 1958 to 2022 (65 years) as monthly anomalies relative to 1981–2010 (RECON). It is based on monthly mean 2-m temperatures at 15 fixed stations that are spatially extrapolated to the entire continent using weights derived from the European Centre for Medium-Range Weather Forecasts 5th generation reanalysis (ERA5). Infilling of the fixed station records are performed where necessary to yield complete time series for 1958–2022. Variability and trends are tested at independent stations that have much shorter periods of record. RECON is designed for Antarctic climate variability and change applications for large spatial scales and extended time scales.

Published: November 2024

Abstract. Large-sample datasets are essential in hydrological science to support modelling studies and advance process understanding. However, these datasets often lack standardization, which impedes their combination. Caravan is a community initiative to create a large-sample hydrology dataset of meteorological forcing data, catchment attributes, and discharge data for catchments around the world. Compared to existing large-sample hydrology datasets, the focus of Caravan is to use globally consistent forcing and attribute data to facilitate global studies. Caravan is a community project designed to be expanded by members of the hydrological community using a common cloud-based framework. This dataset is currently the 6th extension to Caravan, based on a subset of hydrological discharge data and station-based watersheds from the Global Runoff Data Centre (GRDC), which are covered by an open data policy. The GRDC is an international data centre operating under the auspices of the World Meteorological Organization (WMO), which collects quality-controlled river discharge data and associated metadata from the National Meteorological and Hydrological Services (NMHS) of WMO Member States. The dataset covers stations from 5,356 catchments and 25 countries, spans the years 1950–2023. This takes the total number of Caravan catchments (core dataset plus extensions) to 22,372 (1589 catchments accounting for duplicates). This extension is released under a CC-BY-4.0 license that allows redistribution and is publicly available on Zenodo: https://zenodo.org/records/14006282 (Färber et al., 2024). We encourage additional NMHS to make their data available under open licenses so that it can be included in future versions of the extension.
PL1GD-T – gridded dataset of the mean, minimum and maximum daily air temperature at the level of 2 m for the area of Poland at a resolution of 1 km × 1 km
Authors: Jaczewski Adam , Marosz Michał , Miętus Mirosław
Published: November 2024

Abstract. This paper presents a high-resolution gridded dataset of daily minimum (TN), mean (TG) and maximum (TX) near-surface air temperatures over Poland, covering the period from 1951 to 2020, with a spatial resolution of 1 km2. PL1GD-T dataset was developed using radial basis functions (RBFs) applied to quality-controlled observations from ground weather stations from the Institute of Meteorology and Water Management – National Research Institute. Cross-validation methods evaluated the gridding procedure on a monthly basis. The linear RBF was employed by hold-out cross-validation (HO-CV) as the most suitable for the gridding procedure among other RBFs. The leave-one-out cross-validation (LOO-CV) was performed to ensure the ability to reproduce the original characteristics variability. The values of the scores averaged over all stations for individual months are in range 0.3–0.2, 0.3–0.2, 0.1–0.2 for the bias, in range 1,23–1,46, 0.69–0.92, 0.84–0.99 the root-mean-squared difference (RMSD) and in range 0.91–0.97, 0.98–0.99, 0.98–0.99 for the correlation for TN, TG and TX, respectively. The RSMD is clearly altitude dependent, increasing from low-land to mountainous regions. The dataset's scope and resolution allowed robust estimation of local climate variability characteristics and observed trends. The availability of high-resolution datasets in both spatial and temporal contexts is essential for climate change impact analysis on a smaller scale. This new dataset provides a quality-validated, high-resolution, and open-access dataset that could be utilised by society, administrative bodies, or research institutions for further analysis. The dataset is publicly available from the repository of the Institute of Meteorology and Water Management – National Research Institute under https://doi.org/10.26491/imgw_repo/PL1GD-T (Jaczewski et al., 2024).
Machine-learning-based virtual load sensors for mooring lines using simulated motion and lidar measurements
Authors: Gräfe Moritz , Pettas Vasilis , Dimitrov Nikolay , Cheng Po Wen
Published: November 2024

Abstract. Floating offshore wind turbines (FOWTs) are equipped with various sensors that provide valuable data for turbine monitoring and control. Due to technical and operational challenges, load estimations for mooring lines and fairleads can be difficult and expensive to obtain accurately. This research delves into a methodology where simulated floater motion measurements and wind speed measurements, derived from forward-looking nacelle-based lidar, are utilized as inputs for different types of neural networks to estimate fairlead tension time series and damage equivalent loads (DELs). Fairlead tension is intrinsically linked to the dynamics and the position of the floater. Therefore, we systematically analyze the individual contribution of floater dynamics to the prediction quality of fairlead tension time series and DELs. Wind speed measurements obtained via nacelle-based lidar on floating offshore wind turbines are inherently influenced by the platform's dynamics, notably the rotational pitch displacement and surge displacement of the floater. Consequently, the lidar wind speed data indirectly contain the dynamic behavior of the floater, which, in turn, governs the fairlead loads. This study leverages lidar-measured line-of-sight (LOS) wind speeds to estimate fairlead tensions. Training data for the model are generated by the aeroelastic wind turbine simulation tool, openFAST, in conjunction with the numerical lidar simulation framework ViConDAR. The fairlead tension time series are predicted using long short-term memory (LSTM) networks. DEL predictions are made using three different approaches. First, DELs are calculated from predicted time series; second, DELs are predicted using a sequence-to-one LSTM architecture, and third, DELs are predicted using a convolutional neural network architecture. Results indicate that fairlead tension time series and DELs can be accurately estimated from floater motion time series. Further, we found that lidar LOS measurements do not improve time series or DEL predictions if motion measurements are available. However, using lidar measurements as model inputs for DEL predictions leads to similar accuracies as using displacement measurements of the floater.

This represents a new paradigm in plastic and reconstructive surgery.
EEG-based discrimination of nociceptive pain levels generated by noxious laser stimulation
Authors: Reyes Galaviz Rogelio Sotero , Villaseñor Pineda Luis
Published: November 2024

Nociception is a sensory process provoked by external stimuli that trigger physiological reactions experienced as pain. The way it is perceived becomes subjective, as it can vary depending on the emotions and behavior of each person, so analog pain scales have been developed, and new technologies are trying to find biomarkers that make these evaluations more quantitative and less subjective. In this research, we propose to detect and classify nociceptive pain caused by applying a transcutaneous laser with three different intensities using information from Electroencephalographic (EEG) signals. This study aims to be able to classify between pain and non-pain states of subjects using the biosignals from the database; it also is planned to classify between 3 levels of pain linked in an assumption to the three intensities of lasers used as noxious stimuli.

Authors: Singh Laisom Sharmeswar , Singh Laishram Nirtish
Published: November 2024

Problem-solving involves overcoming obstacles that hinder goal attainment and finding optimal solutions to issues. This ability empowers learners to address challenges they encounter effectively. Consequently, problem-solving has become one of the most crucial 21st-century skills for better future adjustment in a complex society. This paper examines gender, family type, school type, and locality as correlates of problem-solving ability. The researchers conducted descriptive research with 1,200 secondary school students from the Thoubal district of Manipur. They used the Problem-solving Ability Test (PSAT), which they constructed based on five dimensions of problem-solving ability, to collect data. The findings reveal that male students significantly outperformed female students in the PSAT. Although students from joint families performed slightly better than those from nuclear families, the difference was insignificant. Additionally, students in private schools significantly outperformed those in government schools. Moreover, students from urban schools substantially outperformed those in rural schools on the PSAT.

Authors: Alshammari Adel Ayed , Alshammari Norah Hamdan M
Published: November 2024

This study investigates job burnout among female primary school teachers in Saudi Arabia, a relatively under-researched area in the region. It employs a structured questionnaire focusing on three dimensions: emotional exhaustion, Human relations, and Diminished Personal Accomplishment. The findings highlight a significant prevalence of emotional exhaustion, the most acute form of burnout experienced by these teachers. This high level of emotional fatigue is attributed to the demanding nature of their profession, societal expectations of women, and ongoing changes in the education sector. While diminished personal accomplishment receives a moderate rating, indicating challenges, human relations are managed effectively, likely influenced by cultural and religious norms emphasising respectful interaction. The study also examines the impact of social status and student gender on burnout. It concludes that social status doesn’t significantly affect burnout levels, but there’s notable higher burnout among female teachers who solely teach boys. Additionally, burnout varies with teaching experience, potentially due to differences in workload. This research contributes to understanding job burnout in female primary school teachers, emphasising the need for supportive measures in education.

Published: November 2024

The paper addresses issues of providing the representative experiments with fuel rods of fast reactors in central experimental channel of the IGR thermal pulse reactor. Preliminary calculations demonstrated a possibility to receive quite intensive field of fast neutrons in the IGR using converters of various designs. For a shift to such tests of fuel rods of fast reactors in the IGR, experimental substantiation of calculation studies is required. It was suggested to implement the experimental substantiation using a set with two types of fuel rods, one of which operates in thermal spectrum of neutrons and another one – in a neutron spectrum obtained using the converter. The design of such an experimental device has been developed; its performance has been calculated. The safety justification for its testing in the IGR has been carried out.

Published: November 2024

The paper is devoted to the problem of constructing nuclear power reactors based on the synthesis of light elements. This problem is currently subject to assessment under options of thermonuclear reactors operating with high-temperature plasma. In such reactors, plasma is isolated from the walls of the reaction chamber using a magnetic field. Even in advanced designs of thermonuclear reactors, temperature regime is far from the conditions for ensuring optimal interaction cross sections of the source nuclei. Despite many years of work, the task of efficient plasma isolation is difficult to solve. The size of the reaction chambers increases, predicted costs of constructing an effective reactor, even in version with the deuterium-tritium reaction, which has a maximum cross section and minimum energy of interacting nuclei. The article considers a version of the fusion reactor based on the interaction of colliding ion beams in a toroidal magnetic field. This solution provides a cost cutting to trigger the reaction, address the problem of effective retaining of interacting nuclei in the reaction chamber. An example withD–D, D–TandD–3Неreactions shows reactors based on them with low energy losses and small dimensions.

The influence of mangrove forests on estuarine dynamics of dissolved organic matter
Authors: Wölfelschneider Mirco , Dittmar Thorsten , Hatje Vanessa , Seidel Michael
Published: November 2024

Mangroves play a critical role in shaping the composition of dissolved organic matter (DOM) in tropical estuarine systems. They act as bioreactors that transform and degrade imported organic matter before releasing it as DOM and export large amounts of leaf litter that leach additional DOM into estuarine waters. These processes are coupled with highly dynamic hydrological conditions in estuaries, creating complex systems that remain poorly understood. In this study, we used ultra high-resolution Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) to characterize the molecular composition of solid-phase extracted DOM along the Jaguaripe River estuary, Bahia, Brazil, and from mangrove leaf leachates in combination with environmental parameters. Our findings indicate that mangroves fringing the estuary are a significant source of dissolved organic carbon (DOC). DOM derived from mangroves was rich in sulfur-containing and saturated compounds with low oxygen-to-carbon (O/C) ratios, particularly during the dry season. Interestingly, during the rainy season, mangroves also appeared to act as a sink for total dissolved nitrogen (TDN), and aliphatic nitrogen-containing compounds. Mangrove leaf leachate DOM exhibited elevated levels of highly unsaturated compounds with low O/C ratios. We identified 432 unique compounds as indicators of DOM leached from mangrove leaf litter. Furthermore, we developed a novel molecular tracing index, IManL, which allowed us to successfully track mangrove leaf–derived DOM within the estuary and beyond. By combining our index with other established DOM indices, we gained a deeper understanding of how diverse DOM sources shape estuarine DOM pools, underscoring the significant influence of fringing mangroves in these systems.

ORIAL: EXCLUSION, VULNERABILITY AND ADAPTATION
Authors:   Federal University of Technology, Minna, Sanusi Yekeen Adeeyo
Published: November 2024

People, communities and nations are confronted with exclusion, vulnerability and adaptation. These are found across space and communities in different shades. They reflect the complexity of human societies and the imperfection of the various forces that define, shape and nurture human interactions. These phenomena are related (Nunes, 2021) and all have both vertical and horizontal dimensions. Their vertical dimension derives from their sectoral attribute in terms of economic, social and even political aspects while the horizontal dimension relates to their spatial manifestation. In addition, both exclusion and vulnerability are associated with similar causal factors of historical experiences (slave trade, colonialism, apartheid, postcolonial economic relations) and marginalising governance system including poor space and settlement governance. Exclusion, often called social exclusion (Sen, 2000) could also be an external effect of seemingly good public policy and action. Exclusion, in simple terms, means that some people, communities and spaces are outside the driving and or the active elements of the society. They lie at the margin (Estivill,2003) of the community driving forces. Marginality undermines capability. Hence, Sen (2000) opines that exclusion can be ‘constitutively a part of capability deprivation as well as instrumentally a cause of diverse capability failures’.

Published: November 2024

In the context of contemporary higher education, cultivating students' analytical and critical thinking capabilities is essential for their achievement in both academic and professional arenas. Conventional pedagogical approaches frequently fail to adequately support the advancement of these sophisticated cognitive competencies. Recent studies suggest that reflective and collaborative learning methodologies can significantly strengthen these skills. Nevertheless, there remains a paucity of research concerning the overall effects of these educational strategies on university students. This initial investigation seeks to fill this void by assessing a blended instructional model that combines reflective and collaborative learning techniques to enhance the analytical and critical thinking abilities of students at Yunnan University of Traditional Chinese Medicine. The results indicate that this holistic approach not only improves cognitive skills but also fosters a more engaging and effective educational atmosphere. This research provides empirical validation for the incorporation of reflective and collaborative learning, offering valuable insights for curriculum design and instructional practices within higher education.

In Indonesia, the protection of indigenous peoples' rights in the context of the aviation industry based on Pancasila values faces complex challenges. Although there have been efforts to establish a legal basis that respects these rights, their implementation in the aviation sector is still limited. This research aims to explore the implementation of Pancasila values in the protection of indigenous peoples' rights in the aviation sector and identify collaborative steps that can be taken by the government, the aviation industry, and other stakeholders. Using a descriptive qualitative approach through literature studies, this study evaluates challenges such as the lack of participation of indigenous peoples in aviation project decisions and the lack of effective law enforcement. The results show that cooperation between governments, airlines, civil society, and indigenous peoples is essential to strengthen the protection of their rights. It is also necessary to evaluate the impact of airport development policies to ensure the protection of land rights and the sustainability of indigenous peoples' culture. The involvement of indigenous peoples in the planning of aviation projects is a concrete step to ensure the alignment of aviation infrastructure development with Pancasila values and the rights of indigenous peoples

The background of this research problem is limited access to technology, inadequate facilities, and infrastructure, as well as a lack of managerial support that can affect the effectiveness of curriculum implementation. This study aims to analyze the perception of Driving Teachers regarding the implementation of the Independent Curriculum, focusing on the obstacles they face in the learning process. The method used in this study is quantitative with a descriptive approach, using a questionnaire as a data collection instrument. The data analysis technique uses descriptive analysis of all research data. The results of the study showed that most respondents had a good understanding of the Independent Curriculum, with the respondents' achievement rate reaching 93.38%. However, challenges such as limited internet connections, low understanding of technology, and limited time allocation for the implementation of the Pancasila Student Profile Strengthening Project (P5) can hinder the success of the curriculum. This research is expected to provide recommendations to increase support for Teacher Mobilizers and improve learning conditions in similar areas.
