Launched on 25 April 2018, the Sentinel-3B satellite has already delivered impressive first images from its ocean and land colour instrument, and now the radiometer carried on this latest Copernicus satellite has revealed its talents. Captured on 9 May 2018, this image shows a low pressure system over the UK and Ireland, France, the Bay of Biscay, Spain and part of north Africa. Vegetation appears in red.
The Sentinel-3B satellite lifted off from Russia on 25 April and joins it identical twin, Sentinel-3A, in orbit. This pairing of satellites increases coverage and data delivery for the European Union’s Copernicus environment programme. Both Sentinel-3 satellites carry the same suite of instruments.
The sea and land surface temperature radiometer is particularly sophisticated, measuring energy radiating from Earth’s surface in nine spectral bands, including visible and infrared. It also includes dedicated channels for measuring fires. This early image came from its optical channels.
The image is also featured on the Eumetsat website.
