Understanding discrepancies in soil moisture from SMAP and AMSR2: insights into performance and dry-down behavior

GIScience & Remote Sensing
Understanding the dynamic changes in soil moisture (SM) is crucial for studying land–atmosphere interactions in hydrometeorology. While numerous SM datasets have been developed for passive microwave remote sensing systems operating at various frequencies,
