Sentinel-3 surface temperature radiometer delivers first image Craig MacDonald Mon, 19/10/2026 - 09:53 Image of the week: Antarctic storm in first view from Sentinel-3C's surface temperature radiometer Watching our Earth from space This week's image is the first visible from the Sea and Land Surface Temperature Radiometer (SLSTR) on the new Copernicus Sentinel-3C satellite, following its launch on 15 September 2026. Last Updated Published on The image shows a spring storm off the coast of East Antarctica, drawing warmer, moister air from the southern Indian Ocean into the cold Antarctic air mass. Bands of cloud spiral in towards its centre, while over the open ocean the cloud forms a honeycomb pattern. Sea ice and the edge of the ice sheet lie to the south. In early spring, rapidly increasing sunlight warms the Southern Ocean while the Antarctic interior remains bitterly cold – and the contrast in temperature and pressure between the two brings storms, strong winds, snow and blizzards. This preliminary image from SLSTR's visible channels shows clouds, ice and the surface in fine detail, revealing the clear-sky areas where the instrument's thermal channels – due to deliver their fir
