The Surface Elevation Change (SEC) version 3 product contains two different types of data files:1) quicklook.png of the surface elevation changes.2) NetCDF files containing the surface elevation changes and their associated errorsData are based on ESAs Ku-band radar satellite level-2 data products. Given the longer time span of operation of the satellites, the data are provided at a five-year mean.The algorithms used to derive the product are explained in detail in Simonsen and Sørensen (2017), and Sørensen et al. (2018). The approach used here is the most optimal combination of the XO-, TR-, and PF-algorithm; the data are corrected for both backscatter and leading-edge width, and solved at 1 km grid resolution and averaged in the post-processing to 5 km grid resolution by ordinary kriging.Reference:Simonsen, S.
