The NASA Soil Moisture Active Passive (SMAP) mission will provide a capability for global mapping of soil moisture and freeze/thaw state with unprecedented accuracy, resolution, and coverage. The SMAP instrument includes both a radiometer and a synthetic aperture radar (SAR) operating at the L-band (1.20-1.41 GHz) and will provide global coverage at the equator every 3 days. The SMAP mission will play a critical role in understanding the Earth’s water and energy cycles, improving weather and climate forecasting, and developing disaster prediction and monitoring services.

The NASA Distributed Active Archive Centers (DAACs) at the Alaska Satellite Facility (ASF) and the National Snow and Ice Data Center (NSIDC) will jointly distribute and support SMAP data products. The DAACs will draw upon their unique expertise – ASF with SAR data and NSIDC with cryospheric and remotely-sensed soil moisture data– as well as their shared technologies to provide synergistic data access and support for SMAP products.

In an effort to educate and broaden the SMAP user community, we will present an overview of the SMAP data products as well as when they will be available at the DAACs. NASA DAACs play an integral role in enabling data discovery and usage through the value-adding services they provide. Through this presentation, we will also discuss the tools and services at the ASF and NSIDC DAACs and gain further insight into how the DAACs can enable the user community to seamlessly and effectively utilize SMAP data in their research and applications.
