In: Proceedings of the International Geoscience and Remote Sensing Symposium Proceedings, July 7-11, 2008, Boston, Massachusetts. p. I37-I40.Interpretive Summary:
                                Technical Abstract: During 2007 a field experiment was conducted with a goal of optimizing microwave soil moisture retrieval algorithms for small to medium deciduous trees.  After initial field checkout in Fall 2006, the ComRAD microwave truck instrument system was deployed to a test site with several stands of deciduous paulownia trees. A joint effort of  NASA / GSFC and George Washington University, ComRAD consists of a quad-polarized 1.25 GHz radar and a dual-polarized 1.4 GHz radiometer sharing the same antenna.  ComRAD can function as a ground-based instrument simulator for L band space missions such as SMOS, SMAP, and Aquarius.  In the current study, ComRAD acquired data from April to November 2007 to monitor the seasonal difference in microwave response to soil moisture under deciduous trees.  To conclude the three-year planned field measurement effort, ComRAD will deploy to a natural coniferous pine tree site in 2008.
