High-frequency monitoring of suspended particulate matter (SPM) concentration can improve water resource management. Missing high-resolution satellite images could hamper remote-sensing SPM monitoring. This study resolved the problem by applying spatiotemporal fusion technology to obtain high spatial resolution and dense time-series data fill image-data gaps. Three sources (MODIS, Landsat 8, Sentinel 2) two methods (the enhanced temporal adaptive reflectance model (ESTARFM) flexible (FSDAF))...

Soil moisture plays a crucial role in understanding the hydrological cycle and ecological environment. This research presents an improved change detection method that leverages time series data from Sentinel-1 radar Sentinel-2 optical sensors (2019–2021) to estimate surface soil moisture. The response of backscatter bare was expressed logarithmic form, influence function normalized difference vegetation index (NDVI) on established for various vegetation-covered surfaces. Therefore, impact is...
