The PO.DAAC is pleased to announce the public release of the (Cyclone Global Navigation Satellite System) CYGNSS Science Data Record (SDR) Version 3.1 (V3.1) Level 1 (L1) DDM calibration, Level 2 (L2) wind speed retrieval , and Level 3 (L3) gridded wind speed datasets. Improvements have been made relative to the previous v3.0 L1 and L2 algorithms, as described below. The data are provided in netCDF-4 format and extend from 1 August 2018 to present with an approximate 6 day latency.
L1 – The CYGNSS science antenna gain patterns have been adjusted to improve the accuracy of the ocean surface normalized bistatic radar cross section (NBRCS) calibration. They are adjusted so that the annual....
