AirMOSS – Airborne Microwave Observatory of Subcanopy and Subsurface

Friday, October 2, 2015

AirMOSS mission reached a significant milestone yesterday as we successfully completed all the P-band radar observations of root zone soil moisture for the entire mission, thus meeting the baseline science requirement for science observations.  Over the past 3 years we have conducted 186 science flights over the selected nine biomes in North America during the growth season, which amounted to over 1200 hours including engineering and transit flights.  In addition, the Picarro wavelength-scanned cavity ring-down spectrometer onboard the Purdue Airborne Laboratory for Atmospheric Research (ALAR) aircraft flew 86 hours in 2012 and 2013 to measure the spatial variations of atmospheric CO2 fluxes to validate model simulations of Net Ecosystem Exchange based on AirMOSS’ P-band radar root zone soil moisture measurements.
