Summary: Comparing three 10 m resolution global land cover products (FROM-GLC10, ESRI2020, and ESA2020) in terms of accuracy is crucial for studying global and regional environment protection, sustainable development, and optimizing mapping methods. However, previous validations have lacked field collection points in large regions like Southeast Asia, posing challenges in land cover mapping.

Summary: In this article, two novel features, the Gaussian-weighting spectral (GWS) feature and the area shape index (ASI) feature, are proposed to improve land cover classification with high spatial resolution remotely sensed imagery. Experimental results show that the proposed features can enhance classification accuracies and complement each other to improve classification performance.

Summary: Deforestation in the tropics leads to warming, but the impact on temperature change varies depending on the spatial patterns of forest loss. Fragmented landscapes from deforestation result in smaller temperature increases, while extensive forest loss leads to greater warming.

Summary: The comparison between the CORINE Land Cover dataset for Norway for the reference year 2018 and detailed national land cover and land use data showed that in general, the classification complied with the definitions, but discrepancies were found in detailed and marginal classes. Using classification based on statistical profiles can improve the accuracy of the classification.

Summary: This study aims to investigate the characteristics of atmospheric rivers (ARs) from the western Pacific to Southeast Asia. The results show frequent AR activities in this region during the autumn-winter season, with increasing trends and eastward shift. These dynamic changes contribute to increasing extreme precipitation amounts in the surrounding coastal areas of the South China Sea. This study emphasizes the importance of ARs in understanding the climatology, trends, and variability of regional precipitation in Southeast Asia.

Summary: The study found that the diversity of archaea and bacteria in soil is influenced by land cover types and environmental zones, with archaeal beta-diversity mainly controlled by environmental zones. These results highlight the importance of land cover types and environmental zones for understanding the contributions of soil microbes to nutrient dynamics and ecosystem resilience.

Summary: Agricultural land use change in Southeast Asia is primarily driven by economic growth, but it often leads to negative outcomes for health, food security, gender equality, and economic equality, while positive outcomes are seen in income and employment. Studies suggest synergies between income and food security, and between income and employment, but trade-offs may exist between income and economic equality.

Summary: An important uncertainty in modeling methane emissions from natural wetlands is the wetland area. It is difficult to model wetlands' methane emissions due to various factors, including spatial heterogeneity at different scales. This study investigates the impact of model resolution on simulated wetland methane emissions and finds a strong relation between emissions and resolution, which is sensitive to the sub-grid treatment of the wetland fraction.

Summary: Countries in Southeast Asia are rapidly transitioning to predominantly urban societies, leading to an increase in urban land mainly in river deltas and floodplains, exposing humans and assets to flood hazards. Expected annual flood damage is projected to increase in all countries, with the preferable development pathways being context dependent.

Summary: The study in northern Southeast Asia revealed significant changes in land cover, with an average land use change frequency of 5.4 times. There was a noticeable difference between the annual approach and time-stage approach in determining land use change, emphasizing the importance of selecting an appropriate time period for studying land use change at a local scale.

Summary: This paper assessed four high spatial resolution remote sensing ET products in the Lancang-Mekong River Basin and found variations in their performance across different vegetation types and climate zones. Although these products were able to reflect spatial differences in the basin, they did not show consistent temporal trends or uniform spatial distributions.

Summary: This study used synthetic biotechnology to generate reverse genetics viruses of different genotypes, and developed an effective vaccine candidate against EV-A71. Using antigenic cartography, we found antigenic differences among different genotypes, and several sera were able to effectively neutralize various EV-A71 genotypes. Based on antigenic mapping and neutralization activities, B4 7008-HF and C4 M79 may be potential vaccine candidates against EV-A71.

Summary: The study compares the consistency and reliability of eight global LULC datasets in Mainland Southeast Asia (MSEA) and finds that three datasets (FROM-GLC10, World Cover, and GLC_FCS30) have higher accuracy, while ESA CCI-LC and World Cover have lower correlation. The study also reveals that forests and cropland are the dominant LULC types in MSEA, with variations in the distribution of built-up land and grassland among the datasets. Furthermore, the study shows consistent trends in forest change across the five countries of MSEA over the past two decades for MCD12Q1, ESA CCI-LC, and GLC_FCS30.

Summary: Southeast Asia, home to half of the world's tropical mountain forests, is experiencing increasing loss of mountain forests, particularly in higher elevations, leading to unprecedented carbon loss. The accelerating trend of forest clearance in the region poses a significant threat to international climate agreements and biodiversity conservation.

Summary: This study investigated the seasonal impact of CDOM on light absorption in the Sunda Shelf region of Southeast Asia, showing that CDOM can dominate underwater light absorption and alter the underwater irradiance spectrum, reducing light penetration depth. The results suggest that terrigenous CDOM may contribute to limiting the depth distribution of photosynthetic corals.

Summary: We propose a new algorithm for retrieving fire temperature and radiative power using the short-wave infrared (SWIR) bands of high resolution satellite sensors. The algorithm overcomes the challenge of large solar input compared to thermal emission from fires by modeling the unknown ground reflectance. The algorithm is evaluated using a synthetic dataset that includes atmospheric effects and shows a high correlation between the retrieved fire temperature and radiative power with the actual values.
