Leicester scientists affiliated with the National Center for Earth Observation (NCEO), headquartered at Space Park Leicester, have mapped measures of land surface temperature—topping out at 52°C—as measured by the pair of Sentinel-3 satellites in orbit more than 800km (500 miles) above Earth. Their map shows the temperature of the Earth's surface at approximately 10:20 am on Monday morning as seen by the satellites' Sea and Land Surface Temperature Radiometer (SLSTR). The satellites are operated by the European Space Agency (ESA).
