Abstract

Three algorithms for the retrieval of soil moisture content (SMC) from MetOp-ASCAT acquisitions have been developed and compared. This activity has been carried out in the framework of the ASCAT Round Robin exercise that was supported by ESA as a part of the Climate Change Initiative Phase 1 Soil Moisture Project. The algorithms have been developed and tested using the ASCAT Round Robin data package (ASCAT – RRDP) that was distributed among the partners of the project for developing and validating the algorithms and that was composed by a selection of 150 test sites derived from the International Soil Moisture Network (ISMN) was used. The locations of the in situ soil moisture measurements used for the Round Robin represent a wide range of climate conditions, covering a wide variety of vegetation types and vegetation density classes.
