Summary
[edit]DescriptionLand Surface Temperature in Siberia.png |
English: Siberia is experiencing its second heatwave of 2020. Many historical temperature records have been broken, including in Verchojansk (according to unverified reports) – a town in the east of Siberia known for its exceptionally cold winters – which broke its all-time temperature record hitting 38.0°C on 19 June 2020 against a previous record of 37.3°C on 25/07/1988. This image shows the Land Surface Temperature (LST) obtained from Copernicus Sentinel-3A satellite data acquired on 19 June 2020. LST can be thought of as showing “skin surface temperatures of the Earth” and in this acquisition, data shows large areas of Siberia’s LST (within the Arctic Circle) exceeding 40°C. These significative LST values are due to the combination of the heatwave and the scarce cloud coverage over the area. Warning: this data shows Land Surface Temperature not air temperature at ground level. The Copernicus Sentinel-3 mission is composed of two twin satellites, Sentinel-3A and Sentinel-3B that can measure thermal parameters for both land and marine environments. This allows us to derive parameters such as Land Surface Temperatures over periods of time and compare from year to year. Scientists study the influence of this parameter on glaciers, ice sheets, permafrost, the vegetation in Earth's ecosystems, and can even study how the increasing concentration of atmospheric greenhouse gases affect land surface temperature. |
