- NASA Earthdata Data Pathfinders
- Data Pathfinders guide users through the process of selecting application-specific datasets and learning how to use them through intuitive tools, facilitating equal and open access to the breadth of NASA Earth science data. The pathfinders are intended to familiarize users with and provide direct links to the applicable, commonly-used datasets across NASA’s Earth science data collections. After getting started here, there are numerous NASA resources that can help develop one’s skills further.

How do I access Soil Moisture Active Passive (SMAP) mission data?
SMAP data and data products are distributed by two different NASA Distributed Active Archive Centers (DAACs): the Alaska Satellite Facility (ASF) and National Snow and Ice Data Center (NSIDC).
SMAP radar data is only distributed by ASF and can be accessed here (registration is required for download). SMAP radar data can be analyzed using MapReady. Note: there is only 2.5 months of collected radar data.
All other SMAP datasets (radiometer data) and data products (soil moisture) are distributed by NSIDC. A number of tools work with SMAP data, including ones included in ARSET trainings:
