North American ecosystems are critical components of the global carbon cycle, exchanging large amounts of carbon dioxide and other gases with the atmosphere. 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.

AirMOSS mission graphicAirMOSS is using an airborne ultra-high frequency synthetic aperture radar that has the capability to penetrate through substantial vegetation canopies and soil to depths down to approximately 1.2 meters. For AirMOSS, NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) is being flown on a Gulfstream-III aircraft. Extensive ground, tower, and aircraft in-situ measurements are validating root-zone soil measurements and carbon flux model estimates. The surveys will provide measurements at 100 meter spatial resolution and at sub-weekly, seasonal, and annual time scales.
