Due to the recent release of the CYGNSS Ocean Surface Heat Flux Climate Data Record (CDR) v1.0 (DOI: 10.5067/CYGNS-C2H10) dataset producing data at the same latency and frequency as the older Science Data Record (SDR) v1.0 (DOI: 10.5067/CYGNS-L2H10) dataset and ongoing efforts to update the SDR with a newer version, the data provider has decided to cease continuing production of new data for the CYGNSS SDR V1.0 dataset, which will complete the historical processing record of this dataset covering a period from 18 March 2017 to 30 September 2020. Users seeking the most recent CYGNSS Ocean Surface Heat Flux data, which also utilizes the highest quality wind speed inputs from CYGNSS, are advised to transition to using the CDR v1.0 dataset.
