Vertex is the Alaska Satellite Facility's data portal for remotely sensed imagery of Earth. The ASF Datapool offers synthetic aperture radar (SAR) data products for immediate download.
NASA has designated two Distributed Active Archive Centers (DAACs) to hold the SMAP archive. The ASF SAR DAAC will archive and distribute the Level 1 radar products. The NSIDC DAAC will archive and distribute the radiometer and Level 2-4 products.
SMAP data management is governed by NASA's Earth Science Data Policy (adopted in 1991). NASA has developed policy implementation, practices, and nomenclature that Earth science missions use to comply with policy tenets.
Files Removed from the SMAP L1B and L1C RADAR Dataset
On June 7, 2016, the SP_01966_A_002 and SP_01966_A_003 files were removed from the SMAP L1C RADAR dataset, due to a problem with the Antenna Azimuth file used to process this half-orbit. The SMAP Science Data System (SDS) is working to correct the Antenna Azimuth file and regenerate these half-orbits. Once ASF receives the new file, it will be made available through Vertex and EarthData Search.
