摘要：
The integration of microwave and multispectral data is an emerging technique allowing frequent monitoring of the vegetation biomass and health status. This study aims at integrating Sentinel-1 (S-1) and Sentinel-2 (S-2) acquisitions for estimating the biomass and assessing the water status of agricultural vegetation. The proposed method has been developed and tested on an agricultural area located in Tuscany, central Italy, by considering the S-1 and S-2 acquisitions collected during the summer season of 2022 on a grain sorghum plot. The method combines vegetation volumetric water content (m(v)) estimated from SAR data and optical/infrared vegetation indexes, in particular NDRE which presented the best correlation with the in-situ PRI measurements. The results show a relationship and trend between NDRE and m(v), although for a limited dataset.
