Ocean Vector Winds

The PO.DAAC is pleased to announce the public release of the Cross-Calibrated Multi-Platform Winds Level 4 Version 3.1 datasets produced by Remote Sensing Systems (RSS).

The PO.DAAC is pleased to announce the public release of the Cyclone Global Navigation Satellite System (CYGNSS) data products from the CYGNSS science team including a level 3 ocean microplastic concentration v3.2 dataset.

The PO.DAAC is pleased to announce the public release of the Cyclone Global Navigation Satellite System (CYGNSS) data products from the CYGNSS science team including a level 2 surface heat flux v3.2 dataset.

The 2024 International Ocean Vector Winds Science Team meeting was held May 29-31 in Salt Lake City, Utah, USA.

The PO.DAAC is pleased to announce the public release of the (Cyclone Global Navigation Satellite System) CYGNSS Science Data Record (SDR) Version 3.2 (V3.2) Level 1 (L1) DDM calibration, Level 2 (L2) wind speed retrieval, Level 3 fully developed seas (L3 FDS) gridded wind speed, and Level 3 merged (L3 MRG) wind speed data products. L3 MRG is a new product which combines the L2 FDS and Young Seas Limited Fetch (YSLF) winds and eliminates the need to choose between them depending on sea state development and the proximity to storms. The data are provided in netCDF-4 format and extend from 1 August 2018 to the present with an approximate 6 day latency.

The 2024 International Ocean Vector Winds Science Team meeting will be held Salt Lake City, Utah, USA on May 29 - 31.

The 2023 International Ocean Vector Winds Science Team meeting will be held at Online on Wednesday Oct. 4, Nov. 1, and Nov. 15. Meeting Registration.

Marine heatwaves are periods of persistent anomalously warm ocean temperatures, which can have significant impacts on marine life as well as coastal communities and economies. Scientists at the Physical Sciences Laboratory (PSL) are working to characterize marine heatwaves, understand how they form and dissipate, and predict them in advance.

The PO.DAAC is pleased to announce the availability of the CYGNSS Level 2 Ocean Surface Heat Flux Climate Data Record (CDR) Version 1.2.

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.

Known as COWVR and TEMPEST, the duo is demonstrating that smaller, less expensive science instruments can play an important role in weather forecasting.

It's been six years since the CYGNSS constellation was launched. Over that time, it has grown from a two-year mission measuring winds in major ocean storms into a mission with a broad and expanding variety of goals and objectives.

Working together, two instruments could open the door for a more efficient, cost-effective way to gather key information for weather forecasting.
