Both the wildfires outbreak could be clearly seen on Sentinel-3 OLCI True Colour RGB imagery (see Figures 1 and 2). By 12 August Danish firefighters had been called in to tackle the second blaze and extinguish it.
Wildfires are a growing problem on Greenland, despite the lack of forests, due to the drying of tundra and the increasing number of tourists.
Satellite data helps in monitoring and supporting this new phenomenon, which has been poorly observed in the past. In fact, the Danish Meteorological Institute (DMI) helps the authorities on Greenland, by providing special weather forecasts for the area. Twice a day they send nine different wind charts reaching 36 hours ahead and with a comment from the forecaster. DMI forecasters on Greenland have held some ad hoc briefings with Joint Arctic Commando about the weather.
