NOAA STAR produces two lines of gridded 0.02deg super-collated L3S LEO datasets from Low Earth Orbiting (LEO) satellites, one from the NOAA afternoon JPSS (L3S_LEO_PM) and the other from the EUMETSAT mid-morning Metop-FG (L3S_LEO_AM). The L3S_LEO_PM is derived from JPSS satellites (in v2.80, NPP and N20) with VIIRS sensor onboard (0.75km/nadir). The L3S_LEO_PM dataset is produced by aggregating L3U datasets from two JPSS satellites ( https://doi.org/10.5067/GHVRS-3UO28 and https://doi.org/10.5067/GHV20-3UO28 ) and covers from Feb 2012-present. The L3S-LEO-PM data are reported in two files per 24hr interval, one daytime and one nighttime (nominal JPSS local equator crossing times around 01:30/13:30). Data is in NetCDF4 format, compliant with the GHRSST Data Specification version 2 (GDS2). The Near-Real Time (NRT) L3S-LEO data are archived at PO.DAAC with approximately 6 hours latency and then replaced by the Delayed Mode files about 2 months later, with identical file names. In addition to SST, the L3S-LEO files report the location and intensity of thermal fronts. The NRT/DM data are seamlessly stitched with the full-mission Reanalysis (RAN). The ACSPO L3S products are monitored and validated against in situ data in the NOAA iQuam system ( https://www.star.nesdis.noaa.gov/socd/sst/iquam ) in the NOAA SQUAM system ( https://www.star.nesdis.noaa.gov/socd/sst/squam ). Quality of SST imagery, clear-sky mask and thermal fronts is evaluated in the NOAA ARMS system ( https://www.star.nesdis.noaa.gov/socd/sst/arms ). NOAA plans to include data from other afternoon platforms and sensors, such as N21 and Aqua MODIS, into the future releases of the L3S_LEO_PM.

The DTM is a compilation of multibeam echosounder surveys acquired in 2013. The resolution is 1/64 arc-minutes (~30m). Surveys are located on the Capbreton Submarine Canyon (France) with depths from -4.7m to -344.9m. Depths are referenced to the Lowest Astronomical Tide and the coordinates are expressed into the WGS84 reference frame. The surveys which compose the DTM are S201306500-09 and S201306500-11. Data and metadata associated to these surveys are available on the website http://diffusion.shom.fr/pro/lots-bathy.html. The DTM is not to be used for navigation.

The main objective of the SWIM Level 2S (L2S) product is to provide along-track directional wave spectra measures, as well as the integrated parameters of the associated wave systems (wave length, significant wave height, direction), over the global ocean, as observed with SWIM instrument onboard CFOSAT. CFOSAT (Chinese French Ocean SATellite) is a french-chinese mission launched in 2018, whose aim is to provide wind (SCAT instrument) and wave (SWIM instrument) measurements over the sea surface. The wave spectra and their associated partitions are provided independently for each SWIM incidence (from 2° to 10°), together with the sigma0 resampled at a 20m resolution. They are complemented with information from the nadir beam such as the sigma0, wind speed, significant wave height or rain flag. The SWIM level 2S (L2S) product is generated in delayed mode, a few days after acquisition. It complements the Near-Real Time (NRT) L2 product delivered by the CWWIC center by providing an alternative and evolutive processing to test and implement quickly new algorithms for the wave inversion over the whole mission archive. These evolutions may take advantage of better ancillary data not available in NRT (ice mask product, best estimates of wind or wave model), of the combination with wind measurements from the onboard SCAT scatterometer. The product is also designed to handle complex situations such as coastal areas and heterogeneous seas. These complex situations are by nature of particular scientific interest (e.g. wind wave interactions, wave evolution in coastal region). This version 2 improves the previous release in particular through a new empirical modulation transfer function (MTF) and better partitioning. The dataset is also lighter in size. It has been completely reprocessed from SWIM Level 1 archive. Note that the dataset is split on the access server in two different sub-versions (**2.0** for the L2S using Level 1 in OP06 version, **2.1** for the L2S using Level 1 in OP07 version). No major differences are expected. The SWIM L2S product is generated and distributed by Ifremer / CERSAT in the frame of the Ifremer Wind and Wave Operation Center (IWWOC) co-funded by Ifremer and CNES and dedicated to the processing of the delayed mode data of CFOSAT mission.

The mean and time-varying position of the main Southern Ocean polar fronts has been calculated from a combination of gridded altimetric sea level anomalies and a new climatology of mean sea level constructed from historical data and ARGO T / S profiles.

This dataset provides the meridional and zonal components of both the stress-equivalent wind (U10S) and wind stress (Tau) vectors. The ERA* product is a correction of the ECMWF Fifth Reanalysis (ERA5) output by means of geo-located scatterometer-ERA5 differences over a 15-day temporal window. The product also contains ERA5 U10S and Tau. The data are available through HTTP and FTP; access to the data is free and open. In order to be informed about changes and to help us keep track of data usage, we encourage users to register at: https://forms.ifremer.fr/lops-siam/access-to-esa-world-ocean-circulation-project-data/ This dataset was generated by ICM (Institute of Marine Sciences) / CSIC (Consejo Superior de Investigaciones Científicas) and is distributed by Ifremer / CERSAT in the frame of the World Ocean Circulation (WOC) project funded by the European Space Agency (ESA).
