OPERA Surface Displacement from Sentinel-1 Static Layers validated product (Version 1)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/snwg/opl3disps1st-v1
The Observational Products for End-Users from Remote Sensing Analysis (OPERA) Surface Displacement (DISP) from Sentinel-1 (S1) Static Layers (DISP-S1-STATIC) validated product contains static radar geometry layers associated with the OPERA Surface Displacement (DISP) from Sentinel-1 (DISP-S1) validated product.
Description
Due to the S1 mission’s 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 DISP-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. DISP-S1-STATIC products provide spatial coverage across North America, encompassing the United States, U.S. territories within 200 km of the U.S. border, Canada, and mainland countries from the southern U.S. border to Panama.

These products are generated from Sentinel-1 Interferometric Wide (IW) swath mode acquisitions starting in mid-2016. The DISP-S1 products are available in the associated OPERA Surface Displacement from Sentinel-1 validated product (Version 1) dataset. The OPERA DISP-S1-STATIC product contains modified Copernicus Sentinel data (2016-2026).
The OPERA project is funded by NASA’s Satellite Needs Working Group (SNWG) which provides data products developed to meet the needs of stakeholders from US government agencies.
