Earth’s surface is covered by 70% ocean. Rising seas caused by climate change affect everyone across the globe, from coastal communities to those living inland. Growing up in landlocked Zimbabwe, NASA JPL engineer Shailen Desai was far from the ocean but still experienced its effects on the climate. Now, he is contributing to an international effort to track our rising seas.
Studying sea level rise today will help us better understand its impact on tomorrow. After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL. The launch of the Sentinel-6 Michael Freilich satellite will provide new and better insights about our Earth’s changing ocean.
Our planet is changing. Our ocean is rising. And it affects us all. That’s why a new international satellite will continue the decades-long watch over our global ocean and help us better understand how climate change is reshaping our planet.
Animation of the retrieved ocean surface wind speed over the period of 1 August 2018 to 22 October 2020, produced using the CYGNSS Level 3 Science Data Record (SDR) Version 3.0 dataset.
Animation of the retrieved ocean surface wind speed over the period of 1 August 2018 to 22 October 2020, produced using the CYGNSS Level 3 Science Data Record (SDR) Version 3.0 dataset, which provides wind speed data retrieved from the Delay Doppler Mapping Instrument (DDMI) aboard the CYGNSS satellite constellation. The dataset can be accessed from the PO.DAAC Portal at https://doi.org/10.5067/CYGNS-L3X30 (DOI: 10.5067/CYGNS-L3X30).
The PO.DAAC is pleased to announce the public release of the CYGNSS Science Data Record (SDR) Version 3.0 datasets. The SDR Version 3.0 collection provides a total of 3 unique datasets, each corresponding to processing levels 1 (L1), 2 (L2) and 3 (L3), respectively. While there is quite a large number of variables and measurement parameters in each dataset, the primary measurement in L1 is the Bistatic Radar Cross Section (BRCS) and in both L2 and L3 it is wind speed (meters per second).
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.
Animation of the estimated ocean surface latent (top) and sensible (bottom) heat fluxes over the period of 18 March 2017 to 31 August 2020, produced using the CYGNSS Level 2 Ocean Surface Heat Flux Climate Data Record Version 1.0, which provides the time-tagged and geolocated ocean surface heat flux parameters with 25 x 25 kilometer resolution using wind speed data provided by the Delay Doppler Mapping Instrument (DDMI) aboard the CYGNSS satellite constellation.
The PO.DAAC is pleased to announce the public release of the CYGNSS Level 2 Ocean Surface Heat Flux Climate Data Record (CDR) Version 1.0.
