AirMOSS  

Definition

  • The NASA Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) investigation provided high-resolution observations of root-zone soil moisture over nine major North American biomes. The campaign goals were to quantify the impact of variations in soil moisture on the estimation of regional carbon fluxes and to extrapolate the reduced-uncertainty estimates of regional carbon fluxes to the continental scale of North America. The AirMOSS campaign used an airborne ultra-high frequency synthetic aperture radar flown on a Gulfstream-III aircraft to derive estimates of soil moisture down to approximately 1.2 meters. Extensive ground, tower, and aircraft in-situ measurements were collected to validate root-zone soil measurements and carbon flux model estimates. (en)

Root-zone soil measurements can be used to better understand these carbon fluxes and their associated uncertainties on a continental scale. The goal of the Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) investigation is to provide high-resolution observations of root-zone soil moisture over regions representative of the major North American climatic habitats (biomes), quantify the impact of variations in soil moisture on the estimation of regional carbon fluxes, and extrapolate the reduced-uncertainty estimates of regional carbon fluxes to the continental scale of North America.); update Definition (https://science.nasa.gov/missions/airmoss/);
