PO.DAAC

The Level 4 MUR SST data processing has recently been updated to use GHRSST L2P SST data inputs from the NASA Earthdata Cloud (AWS-West2) in accordance with the transition of PO.DAAC data and services to be 100% in the cloud by mid Spring 2023.

The PO.DAAC is pleased to announce the public release of the GHRSST Level-4 Reprocessed OSTIA SST v2.0 datasets from the United Kingdom Meteorological Office (UKMO).

This high resolution foundation sea surface temperature (SST) dataset is produced by the UKMO through the Operational Sea Surface Temperature and Ice Analysis (OSTIA) system from multiple satellites and in-situ data.

This announcement is a follow up to the CYGNSS Data Processing Announcement from March 14, 2023.

CYGNSS spacecraft altitudes began to occasionally drop below 500 km beginning on 2023-01-08 during orbit perigee. L1-L3 v2.1 and v3.1 algorithms have recently been updated to properly calibrate samples made below 500 km and their data products beginning on 2023-03-19 now include these samples.

Beginning on 2023-01-08, some CYGNSS L1 samples with fill values for ddm_nbrcs and ddm_les did not receive a proper L1 fatal flag. This occurs only rarely from 2023-01-08 to 2023-02-02, and then slightly more often thereafter. Samples are affected when the spacecraft altitude is below 500km altitude. This affects only the CYGNSS L1 data products. 

The PO.DAAC is pleased to release the WindSat Top of the Atmosphere (TOA) Brightness Temperature (TB) L1C data version 8.0 from Remote Sensing Systems (RSS). The dataset contains Level 1C WindSat TOA TB over both land and ocean, resampled on a fixed regular 0.125 deg Earth grid using Backus-Gilbert Optimum Interpolation covering the period from 2003-Feb-01 to 2019-Jan-02.

PO.DAAC has been preparing for the next generation of NASA Earth observing missions and the migration of the data archive, tools, and services to the Cloud. Part of this transition is determining which tools and services are best for our users in the new environment along with the challenges of delivering data faster and at higher volumes than ever before.

The PO.DAAC is pleased to announce the public release of the Tellus GRACE-FO L3 Release 06.1 version 04 (RL06.1v04) datasets.

This release includes six Monthly Tellus GRACE-FO Level-3 Land and Ocean Mass Anomaly RL06.1v04 datasets from all three data centers (JPL, GFZ, and CSR), which supersede the existing GRACE-FO L3 RL06v04 datasets (DOI: 10.5067/GFLND-3AC64; 10.5067/GFLND-3AG64; 10.5067/GFLND-3AJ64; 10.5067/GFOCN-3AC64; 10.5067/GFOCN-3AG64; 10.5067/GFOCN-3AJ64).
