The PO.DAAC is pleased to announce the public release of the Earth & Space Research, Ocean Surface Current Analyses Real-time (OSCAR) Level 4 Version 2.0 datasets. OSCAR ocean mixed layer velocities are calculated from satellite-sensed sea surface height gradients, ocean vector winds, and sea surface temperature gradients using a simplified physical model for geostrophy, Ekman, and thermal wind dynamics.
Animation of ocean surface current speed over the period January 2020 to December 2021 based on the OSCAR (Ocean Surface Current Analysis Real-time) Level 4, quarter degree grid with a 1 day resolution dataset from Earth & Space Research (ESR). Please note that the missing data are represented by the gray color. OSCAR ocean mixed layer velocities are provided at three quality levels: Final, Interim and Near Real Time with a respective latency of each of approximately 1 year, 1 month, and 2 days.
The PO.DAAC is pleased to announce the public release of the NOAA GHRSST VIIRS L2P/L3U v2.80 datasets onboard the Suomi National Polar-orbiting Partnership (NPP) and the NOAA-20 (N20); designated pre-launch as “Joint Polar Satellite System-1”, or JPSS-1/J1 satellites.
OPeNDAP is a standard interface for transferring, transforming and subsetting earth science data. It’s capable of subsetting by time, space and variable, and is a great tool for those looking to reduce the amount of gridded data required for research or analysis to a specific region, time, or set of variables.
“OPeNDAP in the cloud” is a hosted, Earthdata enterprise service that provides a single interface to all Earthdata cloud data enabled for OPeNDAP. Because of the move to a hosted service, there are some mechanisms that have changed for how users interact with the tool.
As detailed in the 12 July 2021 announcement, PO.DAAC has been migrating datasets to the NASA Earthdata Cloud, hosted in Amazon Web Services (AWS). On January 31, 2022 at 17:00 UTC, PO.DAAC will be removing PO.DAAC Drive access to the Phase 1 datasets. They will be available ONLY through our Earthdata Cloud end-points.

Ocean Surface Wind Speed from CYGNSS SDR V3.1 (1 August 2018 to 10 December 2021)
The PO.DAAC is pleased to announce the public release of the (Cyclone Global Navigation Satellite System) CYGNSS Science Data Record (SDR) Version 3.1 (V3.1) Level 1 (L1) DDM calibration, Level 2 (L2) wind speed retrieval , and Level 3 (L3) gridded wind speed datasets. Improvements have been made relative to the previous v3.0 L1 and L2 algorithms, as described below. The data are provided in netCDF-4 format and extend from 1 August 2018 to present with an approximate 6 day latency.
The Cloud Hackathon was a virtual 5-day collaborative, open science learning experience that was the first of its kind, aiming to support science and applications researchers that use NASA Earthdata to transition to using NASA Earthdata on the cloud. Nearly 50 scientists, DAAC Mentors, and other NASA/DAAC staff participated in the hackathon, which took place November 15 to 19, 2021.
