Abstract

The topsoil moisture defined at meteorological stations and the one defined with the use of MetOp satellite has been compared in the paper. The comparison is made with the measurements at stations located on the USA territory and included in the observation network FLUXNET-AMERIFLUX and Soil Climate Analysis Network (SCAN). The stations are located in different climatic zones, defined according to the vegetation type as per the IGBP classification. The research period is 2007–2012. The satellite observation data are corrected to the in-situ measurements and measurement accuracy is assessed. The assessment has been done for different types of underlying terrains. A good agreement with the real data of in-situ moisture measurements has been shown, which allows to use the satellite soil moisture measurement data in data assimilation systems for numerical weather prediction models.
