Fostering the use of Sentinel images in operational oceanography

Implementing Partner: INTA
Primary Topic: Marine Type of Resource: Application Language: Spanish

Last Update:



A new service has been developed by INTA to incorporate Copernicus Sentinel-3 Sea Surface Temperature data in the Spanish oceanographic viewer PORTUS, hosted by the Spanish government agency Puertos del Estado. These works have been carried out within the scope of Action 2018-1-93 (SGA#6), “Fostering the use of Sentinel images in operational oceanography” which has resulted in the creation of the STERNA tool.

The new service is based on the Sentinel-3 water temperature products, generated by EUMETSAT in the framework of its operational satellite meteorological services. Once a day, data recorded by the satellites are automatically downloaded by STERNA and SST values are extracted for a series of reference points along the Spanish coastlines and the Iberia-Biscay-Ireland region. These point values can be consulted and visualized through PORTUS in the form of time series, along with other available magnitudes and data from different sources. This historical series of satellite data covers a period from April 19, 2016, the launch date of the Sentinel-3A temperature products, to the present. Also a near-real time SST map, with a resolution of 0.01 deg x 0.01 deg, is generated on a daily basis for the IBI region with the best value of Sentinel-3 SST for each pixel. Those areas covered by clouds in the Sentinel-3 product are filled with the ODYSSEA SST L4 product of the Copernicus Marine Service (CMEMS). Additionally, a weekly composite is generated from the daily maps.

All the files generated by STERNA are incorporated into the open data repositories of Puertos del Estado from where they can be downloaded by the scientific community and society in general.

The long-term goal would be to extend the area of interest or create different regional products using Sentinel-3 SST data. Sea surface temperature data are extremely important for multiple applications such as fisheries studies, marine biology, climate change, etc. These satellite data will complement and may be used in conjunction with data from other sources, such as the numerical models of CMEMS or those from other countries.

 

Daily SST maps in NetCDF format can be downloaded here.

Both daily SST maps and point values can be visualized here under "Tiempo real" and "Datos históricos" tabs respectively.
