Comparing Assimilation of Synthetic Soil Moisture Versus C‐Band Backscatter for Hyper‐Resolution Land Surface Modeling

Water Resources Research, Volume 57, Issue 4, April 2021., 2021
Abstract This paper presents the assimilation of synthetic surface soil moisture retrievals and C‐band backscatter signal in a 100‐meter resolution version of the Canadian Land Data Assimilation System (CaLDAS) on footprint scale soil moisture with a time interval of three hours.

Downscaling SMAP soil moisture using radarsat constellation mission (RCM) compact polarimetric SAR data: A case study in southern Ontario

, 2020
This paper presents an improved algorithm for downscaling SMAP soil moisture using C-band SAR data. It is developed using multi-temporal C-band Radarsat Constellation Mission (RCM) compact polarimetric (CP) SAR data. In this improved algorithm, the effect of vegetation on soil moisture retrieval from SAR data is minimized by using a normalized ...
