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 …

During 2007-2009 field experiments have been conducted using the ComRAD microwave
truck instrument system with a goal of optimizing microwave soil moisture retrieval
algorithms for small to medium deciduous and coniferous 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. In the current study,
ComRAD microwave data and ground truth measurements of soil moisture, temperature, soil …
