Summary: Land surface reflectance measurements from the VEGETATION program have provided consistent time-series of NDVI globally, but directional effects need to be corrected using a BRDF correction methodology. The proposed methodology shows significant removal of high-frequency noise caused by directional effects and is computationally efficient for global operation.

Summary: The unbalanced shift in land use and cover patterns due to urban growth increases land surface temperature and leads to the emergence of surface urban heat islands. This study examines the impact of evolving land use and cover patterns on land surface temperature and their correlation with vegetation index and building index. The results show a significant decrease in vegetated areas and an increase in built-up areas, with a corresponding rise in land surface temperature. It is crucial for urban planners and policymakers to address these imbalances and implement sustainable development measures, such as urban greening, to control the rising land surface temperature.

Summary: The drought episodes experienced by Morocco in the 1980s and 1990s had long-lasting effects, leaving some affected areas practically deserted and posing serious problems for environmentalists. This study analyzed changes in vegetation cover in the Rif region of Morocco between 1984 and 2017, contributing valuable data on the consequences of climate change and potential protective strategies for vegetation cover.

Summary: Land cover change and its relationship with floods in the semi-arid environment of the eastern Hindu Kush region were investigated using long-term Landsat image time series and the BFAST method. The results showed that approximately 95% of the study area experienced at least one abrupt change during 1988-2020, with floods being the primary driver of this change.

Summary: Research evaluated LULCC datasets for Brazil, showing that the global HYDE 3.3 dataset is an improvement in representing LULCC but estimates lower magnitudes compared to MapBiomas. Both JULES-ES and BLUE models simulate a slowdown in emissions after 2004, in line with other global models and official reports.

Summary: This paper presents a method for identifying urban land cover changes using pixel-based time series analysis, particularly focusing on breaks in NDVI trends. The research shows that the method performs well in areas with large differences in NDVI dynamics among land cover types, but less so in areas where changes in land cover within pixels are minimal. Future improvements include incorporating spectral information other than NDVI and considering multiple change events per pixel over time.

Summary: The study on the Qinghai-Tibetan Plateau found that early-flowering plants are blooming earlier, while mid-to-late flowering plants showed no significant trend. Pre-season precipitation positively influenced early-flowering plants' flowering dates, while snow cover melt date or duration had no impact on flowering phenology. Temperature may play a larger role than precipitation in regulating flowering phenology in this region.

Summary: This study investigated the footprint and intensity of urban heat island (UHI) in 141 cities in China from 2003 to 2020. The results showed that the daytime footprint of UHI was larger than the nighttime footprint, particularly in smaller cities where the footprint increased over time while plateaued in larger cities. Additionally, high UHI intensity occurred in cities with warm climate during the daytime but in cities with cold climate during the nighttime. These findings are important for mitigating the UHI effect in cities with different urbanization levels and climatic backgrounds.

Summary: This study compares the performance of three satellite sensors (PROBA-V, Landsat 8 OLI, and Sentinel-2 MSI) in global land cover change (LCC) monitoring and evaluates their potential and limitations. The results show that Landsat 8 OLI slightly outperforms Sentinel-2 in global LCC monitoring, while PROBA-V performs the worst. The performance differences among the sensors remain consistent despite variations in data availability and spectral observation regions.

Summary: This study proposed a novel water pricing model, the Water Price at Grid-scale (WPG) model, which dynamically allocates water prices to fine grids for urban residents, spatially determining three different tiers of water prices. The results proved that the WPG model can more accurately price water resources than the current system, and has the potential to alleviate water shortage pressure and be integrated into smart city networks for efficient water resource management.

Summary: In this study, four indicators of land cover change were used to examine the spatiotemporal evolution of global arid ecosystems. The results showed that despite complex land cover changes and anthropogenic interferences, global arid ecosystems experienced positive evolution. However, caution is needed to address potential issues caused by rapid urbanization and farmland expansion.

Summary: Aerosol Optical Depth (AOD) is a critical optical parameter that quantifies the degree of light attenuation by aerosols and serves as a fundamental indicator of atmospheric quality. However, current satellite-based AOD retrieval algorithms suffer from inapplicability under low-light conditions, limiting the development of nighttime AOD retrieval. Under this context, we proposed a novel algorithm, namely Simultaneous Consideration of Artificial and Natural light Sources (SCANS), to obtain nighttime AOD. The proposed SCANS algorithm can effectively obtain nighttime AOD with high quality, thereby advancing research on the diurnal variation of crucial Earth's key elements.
