End Date: Dec 31, 2014
A testbed was developed in Marena, Oklahoma, which will compare soil moisture sensor technology for several years and develop a basis for sensor intercomparison. This testbed was begun with startup funds from NASA and it is planned to continue until the launch of the SMAP mission in 2015. This testbed has multiple technologies, including new technologies such as the COSMOS and GPS reflectometry soil moisture programs. Regular soil moisture and vegetation sampling will be conducted to support the ground truth of the sensors and intensive observation periods will be coordinated. The results will be extended to include verification and validation of watershed networks at several ARS locations throughout the U.S. To accomplish this, temporary networks will be developed and deployed to these watersheds for several months to provide more representative and higher density sampling than was previously available. This will result in a verified, quality controlled set of validation networks for satellite remote sensing of soil moisture, to include not only NASA missions, but ESA and JAXA missions.
