AirMOSS began another ten day campaign imaging its three East Coast forest sites on August 18. The radar will image each of the science sites at Howland Forest, Harvard Forest, and Duke Forest three times over the campaign. Concurrent with the radar imaging, teams from JPL and Harvard University are in the field at the Howland Forest and Harvard Forest sites, respectively, collecting in-situ soil moisture data. In addition, Purdue University's ALAR instrument is doing atmospheric science measurements at the East Coast forest sites this week. The ALAR data will be used to validate the AirMOSS Net Ecosystem Exchange products.
