The PO.DAAC is pleased to announce the public release of the Cyclone Global Navigation Satellite System (CYGNSS) data products from the CYGNSS science team including a level 2 surface heat flux v3.2 dataset. The datasets are provided in netCDF-4 format and extend from 1 August 2018 to the present with an approximate 6 day latency.
The L2 Ocean Surface Heat Flux V3.2 dataset provides time-tagged and geolocated ocean surface heat flux parameters with 25x25 kilometer footprint resolution from the Delay Doppler Mapping Instrument (DDMI) aboard the CYGNSS satellite constellation. The reported sample locations are determined by the specular points corresponding to the Delay Doppler Maps (DDMs). Version 3.2 uses CYGNSS Level 2 (L2) Science Data Record (SDR) Version 3.2 surface wind speeds and ECMWF Reanalysis, Version 5 (ERA5).
The CYGNSS datasets and documents are accessible via the dataset landing page on PO.DAAC web portal. Users are recommended to download the data using the podaac-data-subscriber. We also encourage users to visit PO.DAAC Cloud Cookbook for detailed information about how to access the data from NASA Earthdata Cloud. General information regarding the CYGNSS mission is available from the mission website.
