This constituted a volume of about 205,000 Sentinel-1 Single-Look-Complex (SLC) scenes acquired in Interferometric Wide-Swath mode 9 with a raw data volume of about 0.9 Petabytes. With the goal to estimate seasonal variations of repeat-pass coherence at different repeat intervals, this data set was developed by interferometric processing of all Sentinel-1 SAR data acquired over the course of one year between the 1 st of December 2019 and the 30 th of November 2020. Production of the data set described in this paper was motivated by the need to obtain spatially detailed information on how decorrelation at different repeat intervals affects line-of-sight displacement measurements at C-band (5 GHz), and to use this as a reference in modelling similar decorrelation rates at other wavelengths 8. This model has been extended to support trade studies on NISAR continuity measurements under NASA’s Surface Deformation and Change (SDC) Architecture study 7, which includes constellation concepts at different wavelengths and spacecraft constellation configurations. To assess the performance of planned satellite missions, NASA JPL developed a Science Performance Model for the upcoming NISAR mission 6 to simulate the line-of-sight error associated with mission plan. The data set has been produced to obtain global, spatially detailed information on how decorrelation affects interferometric measurements of surface displacement and is rich in spatial and temporal information for a variety of mapping applications.Īnd thus on i) technical specifications of the interferometric radar constellation such as signal wavelength, interval between consecutive acquisitions, or the orbital tube 5 and ii) the temporal stability of geometric and dielectric properties of the observed target. ![]() The data set encompasses three sets of seasonal (December-February, March-May, June-August, September-November) metrics produced with a pixel spacing of three arcseconds: 1) Median 6-, 12-, 18-, 24-, 36-, and 48-days repeat-pass coherence at VV or HH polarizations, 2) Mean radiometrically terrain corrected backscatter (γ 0) at VV and VH, or HH and HV polarizations, and 3) Estimated parameters of an exponential coherence decay model. The data set is derived from multi-temporal repeat-pass interferometric processing of about 205,000 Sentinel-1 C-band SAR images acquired in Interferometric Wide-Swath Mode from to 3. Coverage comprises land masses and ice sheets from 82° Northern to 79° Southern latitudes.
