The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Comments: | Country: European Union EU 3166-2:EU** Platform Class: 65-Orbiting satellite Operations/Responsible organization: European Space Agency (ESA) Previous Name: N/A Launched Date: 3 April 2014 Commissioned Date: 7 April 2014 Decommissioned Date: April 2021 (7 years of mission) Size: 2.8 m long, 2.5 m wide, 4 m high with 2×10 m-long solar arrays and a 12 m-long radar antenna Mass: 2300 kg (including 130 kg fuel) Instrument: C-band synthetic aperture radar (SAR) at 5.405 GHz NOTES: Sentinel-1, carries an advanced radar instrument to provide an all-weather, day-and-night supply of imagery of Earth’s surface. This C-band Synthetic Aperture Radar (SAR) builds on ESA’s and Canada’s heritage SAR systems on ERS-1, ERS-2, Envisat and Radarsat. Sentinel-1A is a European radar imaging satellite launched in April 2014. It is the first Sentinel 1 satellite launched as part of the European Union's Copernicus programme. The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions. It will track many aspects of our environment, from detecting and tracking oil spills and mapping sea ice to monitoring movement in land surfaces and mapping changes in the way land is used. The radar operates in two main modes: Interferometric Wide swath and Wave. Interferometric Wide swath mode, the default mode over land, has a swath width of 250 km and a ground resolution of 5 x 20 m. Wave mode acquisitions – which can help to determine the direction, wavelength and heights of waves on the open oceans – are 20 x 20 km, acquired alternately on two different incidence angles every 100 km.
