摘要

本研究的主要目的是提出一种基于CYGNSS数据估算土壤湿度的反演算法。将基于变化检测技术的算法应用于CYGNSS数据，该算法在考虑入射效应和不同噪声的情况下，经过多次校正。该算法在北非的一个研究地点得到了验证。与现场数据和ASCAT产品的比较表明CYGNSS产品具有强大的潜力。

Soil Moisture Estimation Using CYGNSS Constellation

The main objective of this study is to propose an inversion algorithm for the estimation of soil moisture from CYGNSS data. The algorithm based on the change detection technique is applied to CYGNSS data after several corrections taking in account the incidence effects as well as different noises. The algorithm is validated on a one study site in North Africa. Comparisons with field data and ASCAT products illustrate a strong potential for CYGNSS products.
