The number of wildfires recorderd an unprecedented new peak this Summer 2021. To prevent this phenomenon, EU Member States, as well as other associated countries, established the European Forest Fire Information System(EFFIS). EFFIS consortium is responsible for the protection of forests against fires in the EU and neighbor countries and provides the European Commission services and the European Parliament with updated and reliable information on wildfires in Europe.
The Current Situation Viewer application on the EFFIS website displays on a map the fires counted by satellites orbiting on the Northern emisphere.*
Summer 2021, based on the forecasts analyzed by the consortium experts, will mark a new negative peak compared to the average trends recorded in past summers as shown in the chart below.

The MODIS sensor, on board of the TERRA and ACQUA satellites, identifies areas on the ground that distinctly hotter than their surroundings and flags them as active fires. The spatial resolution of the active fire detection pixel from MODIS is 1 km.
The VIIRS sensor on board of the NASA/NOAA Suomi National Polar-orbiting Partnership (SNPP) uses similar algorithms to those used by MODIS to detect active fires. The spatial resolution of the active fire detection pixel for VIIRS is 375 m. Additionally, VIIRS is able to detect smaller fires and can help delineate perimeters of ongoing large fires.
