JPL ISS-RapidScat Sigma-0 L1B and L2A, Version 2.0 Dataset Releases

The PO.DAAC is pleased to announce the public release of the ISS-RapidScat Sigma-0 L1B and L2A Version 2.0 datasets, which provide backscatter cross-section (sigma-0) measurements from the RapidScat instrument flown aboard the International Space Station (ISS) from 2014 to 2016. The L1B data were used to derive surface wind vectors provided in the corresponding L2B products (e.g. https://doi.org/10.5067/RSX12-L2C20).

PO.DAAC State of the Ocean (SOTO) is moving to a new URL

SOTO is moving to a new URL at https://soto.podaac.earthdatacloud.nasa.gov/.

Please note that the PO.DAAC State of the Ocean (SOTO) visualization tool is transitioning to the cloud and will no longer be available at its current URL. To access SOTO after the transition, please update your bookmarks to use the new URL by May 31, 2023.

FINAL REMINDER - PO.DAAC Drive and Legacy Tools and Services RETIREMENT April 24, 2023 - Important Information for Users

This is a FINAL REMINDER for all PO.DAAC users to complete the transition of their legacy data access scripts and methods for compatibility with cloud data access endpoints at their earliest convenience, as PO.DAAC Drive and the legacy data access tools and services (specifically LAS, CWS, THREDDS) will retire on April 24, 2023.

To ensure a successful transition for all PO.DAAC users, the PO.DAAC in the CLOUD Forum can be used as the primary entry point to help address technical issues and concerns.

OPERA Dynamic Surface Water Extent from Harmonized Landsat Sentinel-2 provisional product (Version 1) Dataset Release

The PO.DAAC is pleased to announce the release of the OPERA Dynamic Surface Water Extent from Harmonized Landsat Sentinel-2 provisional product (Version 1) Dataset. The input dataset for generating each product is the Harmonized Landsat-8 and Sentinel-2A/B (HLS) product version 2.0. HLS products provide surface reflectance (SR) data from the Operational Land Imager (OLI) aboard the Landsat 8 satellite and the MultiSpectral Instrument (MSI) aboard the Sentinel-2A/B satellite.
