Over the past two decades space-based soil moisture retrieval algorithms have been proposed for both radar and radiometer systems. The SMAP Algorithms Working Group (AWG) was formed to involve the broad science community in providing input to the SMAP project on issues related to the mission soil moisture and freeze/thaw retrieval algorithms. The principal focus of the AWG in the near term is to assist the SMAP project in recommending and evaluating viable retrieval algorithms to be implemented using SMAP radar, radiometer, and joint radar/radiometer measurements. Over the longer term, the AWG will assist in assessing the performance of the SMAP retrieval algorithms in the presence of vegetation, topography, temporal change, and other factors. Both soil moisture and freeze/thaw algorithms are included in the AWG activities. The SMAP Science Data System (SDS) has developed an algorithm testbed facility that is being used by the SMAP project to implement and test the SMAP soil moisture and freeze/thaw algorithms. The testbed is used to generate results that can be reviewed by the AWG. At-launch algorithms will be used for generating the standard mission products, but this will not preclude the development of new and improved techniques in the course of the mission. AWG activities will be carried out through emails, telecons, and workshops. The AWG will also take advantage of member attendance at conferences such as AGU and IGARSS, to meet in person when possible. 1st SMAP Algorithms Workshop
A SMAP Algorithms and Cal/Val Workshop, was held June 9-11, 2009, in Oxnard, CA. This workshop was organized jointly by the SMAP Algorithm Working Group (AWG) and the SMAP Calibration & Validation Working Group (CVWG).
