Data Set Overview
|Data set||Soil Moisture Visualizer|
|Project||Airborne Microwave Observatory of Subcanopy and Subsurface|
|Time Period||2011-08-03 to 2016-12-31|
The goal of the Soil Moisture Visualizer (SMV) is to bring together multiple sources of soil moisture data available for North America into a single platform for visualization and download. The visualizer harmonizes surface and root zone soil moisture data sets that are in diverse native data formats and encompass a range of spatial footprints, soil depths, and measurement frequencies. The SMV consists of a web-based application for visualization and spatial subsetting of the soil moisture data and accompanying REST-based services (being developed) for accessing the data.

Airborne Microwave Observatory of Subcanopy and Subsurface: The goal of NASA’s 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. 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. The AirMOSS soil measurements can be used to better understand carbon fluxes and their associated uncertainties on a continental scale. Additionally, AirMOSS data provide a direct means for validating root-zone soil measurement algorithms from the Soil Moisture Active & Passive (SMAP) mission and assessing the impact of fine-scale heterogeneities in its coarse-resolution products.
