CYGNSS Level 2 Ocean Surface Heat Flux Science Data Record Version 2.0 Dataset Release

PO.DAAC is pleased to announce the release of the CYGNSS Level 2 Ocean Surface Heat Flux Science Data Record (SDR) Version 2.0, which 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).

PO.DAAC Dataset Migration to Earthdata Cloud in AWS - OSCAR datasets

As PO.DAAC continues to migrate its data archive to NASA’s Earthdata Cloud, hosted in Amazon Web Services (AWS), we are pleased to announce the addition of 3 new cloud datasets. In an effort to best support the users as they begin transitioning their workflows or data access points to a cloud-based process, PO.DAAC is making the existing datasets from its archive available from and within the Earthdata Cloud as soon as they are available. Information and tutorials about how to access these datasets can be found on the Cloud Data Migration Page.

Sentinel-6 Michael Freilich Reprocessing Updates: Version 2 Completed, Version F Retired

Reprocessed L1A, L1B and L2 altimetry data from the Sentinel-6 Michael Freilich/Jason CS radar altimeter mission were released through the PO.DAAC for the first time on July 28th, 2022. The new releases include Non-Time Critical (NTC) data reprocessed with the latest Sentinel-6 processing baseline (F06). The new datasets are considered Version 2; they replace the corresponding datasets initially released as Version F. Please see the previous release announcement from July 28th for additional information.
