Measuring heat from space - the Mediterranean heatwave 2021

This map shows the land surface temperature of Greece and surrounding countries on June 30th, 2021.
Whereas weather forecasts use predicted air temperatures, the satellite measures the real amount of energy radiating from Earth – therefore this map better represents the real temperature of the land surface.
The data show that surface temperatures reached over 50°C in many locations including the northwest of Athens and many regions in Turkey. The blue spots visible near Albania are clouds.
