For decades, global soil moisture monitoring from space has depended on reference datasets. Satellite observations, while indispensable, are rarely used alone; instead, their retrieval algorithms are ...
This study introduces two innovative methods—Three-frequency pseudorange combination (TFPC) and Three-frequency carrier phase combination (TFCPC)—for estimating soil moisture using GNSS-IR technology.
Anthropogenic climate change is exacerbating soil moisture droughts globally, but most studies only consider surface layers. Now, a study reveals that global soil moisture droughts are often also ...
