Abstract Spaceborne global navigation satellite system-reflectometry has become an effective technique for Soil Moisture (SM) retrieval. However, the accuracy of global SM retrieval using a single model is limited due to the complexity of land surfac

The potential of monitoring the movement of typhoons using the precipitable water vapor (PWV) has been confirmed. However, monitoring the movement of typhoon is focused on PWV, making it difficult to describe the movement of a typhoon in detail minut

ABSTRACTThe weighted mean temperature (Tm) is a key parameter to calculate the Global Navigation Satellite System (GNSS)-based precipitable water vapour (PWV). Data fusion provides a solution to depict the characteristics of Tm in detail. However, mu
