English: These two images, obtained from data retrieved by the Copernicus Sentinel-3 mission on 25 April 2021, show a cloud-free view of Southern Italy (left) and the sea surface temperature of the Adriatic Sea to the east (right). The absence of cloud cover clearly shows colder water (temperature below 14°C) flowing from the northern Adriatic Sea and meandering along the Italian coast in a narrow stream, whereas water of higher temperatures (above 15.5°C) can be found near the Balkan coast. During the winter of 2021, significant anomalies in sea surface temperature have been observed in this part of the Adriatic Sea. According to the latest sea surface temperature report issued by the Mediterranean Center for Environmental Studies (CEAM), the mean temperature anomaly observed in the Mediterranean basin during February 2021 was 0.9°C, and the seasonally adjusted sea surface temperature trend anomaly reached its highest value since recording began in 1982, 1.4°C. The global sea surface temperature trend in the Mediterranean basin determined using data up to February 2021 equals 1.26°C. In the Adriatic Sea, the observed sea surface temperature trend anomaly in February was only slightly above 1°C. One of the objectives of the Copernicus Sentinel-3 mission is to accurately measure sea and land surface temperature using the Sea and Land Surface Temperature Radiometer (SLSTR) instrument. Coupled with the Ocean and Land Colour Instrument (OLCI) and the Synthetic Aperture Radar Altimeter (SRAL), the SLSTR provides accurate and reliable measurements that support oceanic, environmental and climate monitoring efforts.
