SMAP L1C Radar Half-Orbit High-Resolution σo Data on 1 km Swath Grid, Version 1
Data set id:
SPL1CS0
DOI: 10.5067/NVVUJ0MNG3PN

Overview

This Level-1C (L1C) product provides time-ordered, parsed telemetry data retrieved by the Soil Moisture Active Passive (SMAP) radar during 6:00 a.m. descending and 6:00 p.m. ascending half-orbit passes. The major contents of the product are normalized radar cross section (sigma nought) measurements multilooked into 1 km square instrument swath-based grid cells where the center line of the grid corresponds to the path of the spacecraft nadir on the Earth’s surface.
