description: The Observational Products for End-Users from Remote Sensing Analysis (OPERA) Radiometric Terrain Corrected (RTC) SAR Backscatter from Sentinel-1 (S1) Static Layers (RTC-S1-STATIC) validated product contains static radar geometry layers associated with the OPERA RTC-S1 product. Due to the S1 missionâs narrow orbital tube, radar-geometry layers such as incidence angle, local incidence angle, number of looks, and RTC Area Normalization Factor (ANF) vary slightly over time for each position on the ground, and therefore are considered static. These static layers are provided separately from the OPERA RTC-S1 product, as they are produced only once or a limited number of times, to account for changes in the DEM, in the S1 orbit, or in the static-layers generation algorithm. Static layers are provided as single-band Cloud Optimized GeoTIFF (COG) files, with a map grid matching RTC-S1 products with the same burst ID. The Copernicus global 30â¯m (GLO-30) Digital Elevation Model (DEM) is the reference DEM used for topographic correction and geocoding. The OPERA RTC-S1-STATIC product contains modified Copernicus Sentinel data (2014âpresent). The OPERA project is funded by NASAâs Satellite Needs Working Group (SNWG).
