Fig. 1 - S3 SLSTR (29.07.2021) - Greenland's ice sheet has experienced a "massive melting event" during a heatwave, ~ 8 billion tons a day.
Fig. 2 - S3 OLCI (29.07.2021) - The ice sheet covering the vast Arctic territory, has melted by twice its normal average rate during summer.
The Danish Meteorological Institute reported temperatures over 20°C, over twice the normal average summer temperature, in northern Greenland.
Fig. 3 - S3 OLCI (30.07.2021) - Nerlerit Inaat airport in the northeast of the territory recorded 23.4°C on 29 July, the highest recorded there.
Fig. 4 - S3 SLSTR (30.07.2021) - The Greenland ice sheet, if completely melted, would raise the ocean levels by 6 to 7 metres.
