Land Information System for SMAP Tier-1 and AirMOSS Earth Venture-1 Decadal Survey Missions: Integration of SoilSCAPE, Remote Sensing, and Modeling
The Distributed Active Archive Center (DAAC) for Biogeochemical Dynamics at ORNL is partnering with the University of Michigan and Massachusetts Institute of Technology to develop information technologies for enhancing science return and science data quality from the Soil Moisture Active Passive (SMAP) and the Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) Earth Venture-1 missions. The driving science objective of SMAP is to quantify the land (soil moisture and its freeze/thaw state) control on surface water and energy exchange with the atmosphere. The water and energy flux at the surface is a critical forcing of the weather and climate phenomena. The SMAP data products will enhance the initialization of numerical weather prediction models and provide important constraints on the performance of climate models used in global change assessments and seasonal forecasts. The driving science objective of AirMOSS is to reduce the uncertainty of carbon dioxide sources and sinks over terrestrial ecosystems.
DAAC’s role is to build a science information system framework for harmonizing the life cycles of the variety of data and models needed to generate and validate NASA mission products and to address key driving science questions of the decadal survey missions.
