    • Global stacked sea surface height profiles from Sentinel-3B Synthetic Aperture Radar Mode (SARM) satellite altimeter data (NCEI Accession 0219903)

    Metadata Updated: April 1, 2025

    NetCDF file result_s3b_sarm_stack.nc contains longitude, latitude, number of cycles, sigma, and stacked sea surface height records for 770 Sentinel-3B Synthetic Aperture Radar Mode (SARM) satellite altimeter passes. Repeat cycles were aligned to a common position along a synthetic track having 20239 records between +/-81.419 latitude. Stacking is the median sea surface height profile from multiple repeat cycles. Sigma is the expected one sigma error in a single measurement. The number of cycles is the quantity that passed selection criteria and were included in a stack. Repeat cycles 19 to 38 were used. The interleaved ground track started with cycle 19.
