Combined Sentinel-1A With Sentinel-2A to Estimate Soil Moisture in Farmland [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 In this article, seven filter algorithms were compared. The Lee sigma method was more suitable for estimating soil moisture (SM) than the other filtering methods under different land cover types.
