PO.DAAC

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.

The PO.DAAC is pleased to announce the release of reprocessed L1A, L1B and L2 altimetry data from the Sentinel-6 Michael Freilich/Jason CS radar altimeter mission. This mission aims to provide high-precision measurements of global sea-level that build upon the extensive record of observation from the previous Jason series altimetry missions.

The PO.DAAC is pleased to announce the public release of the GRACE/GRACE-FO Level-4 Monthly Global Ocean Mass Anomaly v1.0 dataset funded by the NASA Heat and Ocean Mass from Gravity ESDR (HOMaGE) project.

This release contains the time series of the averaged monthly Global Ocean Mass Anomalies (GOMA), which are derived from the measurements of the GRACE and GRACE Follow-On (G/GFO) satellite missions.

The PO.DAAC is pleased to announce the public release of the GHRSST Level-4 MW-OI and MW-IR-OI Sea Surface Temperature (SST) v5.1 datasets produced by the Remote Sensing Systems (REMSS).

This release consists of two datasets: MW_IR_OI-REMSS-L4-GLOB-v5.1 and MW_OI-REMSS-L4-GLOB-v5.1. The v5.1 data is updated from the previous v5.0 (DOI: 10.5067/GHMWI-4FR05 and 10.5067/GHMWO-4FR05) with extensive algorithm improvements and upgrades. 

The PO.DAAC is pleased to announce the release of the Surface Water and Ocean Topography (SWOT) Simulated North American Continent Hydrology Datasets. This release provides simulated water surface elevation products that resemble the data to be derived from SWOT Ka-band Radar Interferometer (KaRIn) measurements. 

EUMETSAT has announced that the Meteosat 9 will replace the Meteosat 8 on June 23rd, 2022. It will affect the GHRSST L3C OSISAF Indian Ocean SST dataset (DOI: https://doi.org/10.5067/GHSIO-3CO01). However, the data format and SST L3C process remain unchanged.

The PO.DAAC is pleased to announce the release of the datasets from the Surface Water and Ocean Topography (SWOT) 2019-2020 Prelaunch Oceanography Field Campaign. The campaign was designed to test the performance of several in-situ instruments/platforms in meeting the SWOT Sea Surface Height (SSH) Calibration/Validation (CalVal) requirement, and conducted near the SWOT CalVal crossover location, about 300 kilometers west of Monterey, California, between September, 2019 and January, 2020.
