Thursday, December 21, 2023The PO.DAAC is pleased to announce the availability of the PI-produced Parametrized Rain Impact Model (PRIM) for SMAP Level-2 V1.0 dataset produced by the University of Central Florida (UCF) Remote Sensing Lab (CFRSL), Orlando, FL and the University of Washington (UW) Applied Physics Lab (APL), Seattle, WA. This dataset provides sea water salinity on a 0.25-degree spatial grid and covers March 31, 2015 through October 1, 2021. Additional coverage may be provided in the future depending on the availability of required inputs such as rain rate from the IMERG V6B Final Run product.Each PRIM data file corresponds to one JPL SMAP Level 2B CAP Sea Surface Salinity V5.0 file, and contains coverage for one orbit on a given day. Its primary parameters include sea surface salinity at the surface (PRIM_S0m), at 1m depth (PRIM_S1m), and at 5m depth (PRIM_S5m), as well as ocean stratification probability (PSS). The data are distributed in netCDF4 file format and comply with CF/ACDD metadata conventions.The PRIM dataset and user guide are accessible via the dataset landing page on PO.DAAC web portal. Users are recommended to download the data using the podaac-data-subscriber. We also encourage users to visit PO.DAAC Cloud Data Page for detailed information about how to access the data from NASA Earthdata Cloud. General information regarding the SMAP mission is available from the mission website.DOI:10.5067/PRIMS-2RSW1 - https://doi.org/10.5067/PRIMS-2RSW1Citation:Jacob et al. 2023.

Wednesday, January 3, 2024The PO.DAAC is pleased to announce the public release of the NOAA/STAR GHRSST Level 3S (super-collated) version 2.81 SST datasets, produced from the Low Earth Orbiting (LEO) JPSS (NPP, N20, N21), Metop-FG (Metop-A, B C) and NASA (Aqua, Terra) satellites.The L3S-LEO is a family of global multi-sensor L3S gridded 0.02º resolution SST products. The L3S-LEO-PM (afternoon orbit) SST is derived from VIIRSs flown onboard JPSS satellites (NPP, N20 and N21) and MODIS onboard Aqua, by collating individual satellite ACSPO L3U SST data. It comprises 2 daily files, day and night, corresponding to nominal local equator crossing times around 01:30/13:30, respectively. The L3S-LEO-DY (daily) further combines L3S-LEO-PM and AM SSTs, both day and night, from afternoon (PM; NPP, N20, N21, Aqua) and mid-morning orbit (AM; Metop-A, B , C) satellites, plus Terra MODIS between 2000-02-24 and 2021-12-31, into a single daily SST product.The L3S-LEO-PM and DY datasets are produced with the NOAA enterprise Advanced Clear Sky Processor for Ocean (ACSPO) v2.81 SST system, by the NOAA Center for Satellite Applications and Research (STAR). The datasets are formatted as netCDF-4, in compliance with the Group for High Resolution Sea Surface Temperature (GHRSST) Data Processing Specification version 2.0 (GDS2). Detailed information regarding the GHRSST Level 3S products are available from the GHRSST website and also via PO.DAAC’s GHRSST mission webpage.The near-real time (NRT) data are produced with a 3-6 hours latency, and then replaced with Re-ANalysis (RAN) files, within ~2-months. Both datasets are described and discoverable via the PO.DAAC dataset information pages, and accessible via the Cloud OPeNDAP and Harmony API services. We recommend users to download the data with the podaac-data-subscriber python tool.DOI:L3S_LEO_PM-STAR-v2.81 https://doi.org/10.5067/GHLPM-3S281L3S_LEO_DY-STAR-v2.81 https://doi.org/10.5067/GHLDY-3S281References:  O.

Wednesday, February 28, 2024The Surface Water and Ocean Topography (SWOT) project is pleased to announce the public release of Level 2 Geophysical Data Record products from the onboard nadir altimeter (NALT) and the advanced microwave radiometer (AMR).This release includes the Geophysical Data Record (GDR) from each of the NALT and AMR instruments. The onboard NALT is a Jason-class dual frequency (Ku/C) altimeter. The onboard AMR is also a Jason-class radiometer but with two active strings that facilitate measurements on the left and right sides of the satellite nadir point.Product description documents for these products can be found online at:

<a href="//podaac.jpl.nasa.gov/swot?tab=datasets">https://podaac.jpl.nasa.gov/swot?tab=datasets</a>


<a href="https://www.aviso.altimetry.fr/en/missions/current-missions/swot.html">https://www.aviso.altimetry.fr/en/missions/current-missions/swot.html</a>
The datasets in this release include Cycles 400 to 578 (January 15 – July 10, 2023) during the SWOT commissioning and calibration phases (1-day repeat orbit), and Cycles 1-6 (July 21 – November 23, 2023) during the science phase (21-day repeat orbit). Note that some passes are not available in the later portion of cycle 578, and very early portions of Cycles 402 and 1 during orbit transitions as well as instrument turn on.Starting with this release, NALT and AMR GDR products will continue to be routinely released with a latency of < 90 days from the end of each repeat cycle.Users are advised of the following known limitations in the dataset:

The adaptive retracker has not yet been calibrated, so the adaptive retracker variables should be used with caution.
Users are advised of the following upcoming changes in the datasets:

In the coming weeks, the processing baseline of the SWOT L2 Nadir altimeter products will evolve to use the same MSS (CNES_CLS_2022) and the same MDT (CNES_CLS_2022) as the SWOT KaRIn L2_LR_SSH products.
Users are also advised of the following differences between OGDR, IGDR and GDR:

The OGDR is a non-validated product that is available with a typical latency of < 7 hours.


The IGDR is a partially validated product that is available with a typical latency of < 2 days.


The GDR is a validated product that will become available with a typical latency of < 90 days after the start of release.
