Argentina is facing a historic heatwave with temperatures soaring above 40°C.  On the day this image was acquired, Buenos Aires recorded a temperature of 41.1°C, the second highest in the history of the Argentine capital.

As early as 13:44 UTC (10:44 local time), the total absence of cloud cover provided a clear and detailed view of the area. This enabled an accurate measurement of the land surface temperature, which rose above 54°C near the town of Neuquén, in the Argentine hinterland.

These images, produced using data from the Copernicus Sentinel-3A satellite on 11 January 2022, show a cloudless view (right) and land surface temperature (left) of southern Argentina.

Note: this data shows Land Surface Temperature (i.e. the temperature of the soil), and not air temperature at ground level.

The Copernicus Sentinel-3 twin satellites are fitted with a Sea and Land Surface Temperature Radiometer (SLSTR) instrument, which allows the accurate monitoring of land surface temperature on a global basis.
