PO.DAAC

We are pleased to announce that the new State of the Ocean (SOTO) is deployed and operational through a new URL at https://soto.podaac.earthdatacloud.nasa.gov/.

This is a part of the transition to the cloud. The new SOTO is powered by NASA EOSDIS Worldview, based on a cloud-native implementation. The current SOTO will be retired and no longer accessible in March or April, 2023. We will provide further notifications.

PODAAC is pleased to announce that 11 more datasets have completed migration into our new cloud-based archive in NASA’s Earthdata Cloud, which is hosted in Amazon Web Services (AWS). Information and tutorials describing how to access these datasets can be found on the Cloud Data Migration Page. Users may also find the PO.DAAC Webinar (August 2021) useful as they begin their journey to using cloud-based data.

The Submesoscale Ocean Dynamics and Vertical Transport Experiment (S-MODE) is a NASA Earth Venture Suborbital (EVS-3) mission that utilizes research aircraft equipped with state-of-the-art remote sensing instruments, a research vessel, Wave Gliders, Saildrones, and many other in situ assets. These instruments contribute to an unprecedented view of the physics of submesoscale eddies and fronts, and their effects on vertical transport in the upper ocean.

The PO.DAAC is pleased to announce the public release of the GRACE-FO (GF) Level-2 Monthly Geopotential Spherical Harmonics RL06.1 datasets from the Project Science Data System teams at the Jet Propulsion Laboratory (JPL), German Research Centre for Geosciences (GFZ), and Center for Space Research (CSR).

This release includes three GRACE-FO Level-2 RL06.1 datasets, which are updated from the previous RL06 datasets (DOI: 10.5067/GFL20-MC060, 10.5067/GFL20-MJ060, and 10.5067/GFL20-MG060). The RL06.1 uses the updated L1B calibration product (ACX) which is an updated hybrid accelerometer-transplant that uses observations from both the GF1 and GF2 accelerometers to reduce measurement errors.

The PO.DAAC is pleased to announce the release of the version 5.0 SMAP Sea Surface Salinity (SSS) data from Remote Sensing Systems (RSS).

The major changes in Version 5.0 from Version 4 are: (1) the addition of formal uncertainty estimates to all salinity retrieval products and (2) sea-ice flagging and sea-ice side-lobe correction based on direct ingestion of AMSR-2 brightness temperature (TB) measurements. This is in contrast to Version 4 and earlier versions, in which the sea-ice correction was based on an external sea-ice concentration product.
