Global stacked sea surface height profiles from Sentinel-3B Psuedo-Low Rate Mode (PLRM) satellite altimeter data from 2018-11-23 to 2020-04-24 (NCEI Accession 0219902)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 06, 2026 at 02:39 AM | Dataset Last Updated: October 02, 2020 at 12:00 AM
NetCDF file result_s3b_plrm_stack.nc contains longitude, latitude, number of cycles, sigma, and stacked sea surface height records for 770 Sentinel-3B Pseudo-Low Rate Mode (PLRM) 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.
