🔥 Severe #wildfires have affected #Spain and #France in recent weeks. The GOME-2 Absorbing Aerosol Index (AAI) shows smoke plumes over the countries on 25 and 26 July. The fires are among the largest in decades. They have destroyed homes, caused evacuations and burned extensive areas of land. ⚠️

Here are examples of GOME-2 B&C Level 3 Tropospheric NO2 for two African cities, Nairobi and Casablanca, annual mean 2024. NO2 is produced mainly in combustion of fossil fuels (coal, gas and oil) and especially fuel used in cars. Click images to get larger view.

Nairobi and it's surrounding area. The high NO2 values are over the city itself and the other heavily populated areas near Nairobi. The NO2 values over countryside are much smaller due to lacking traffic.Casablanca, Marocco, and it's surrounding area. The high NO2 values are over the city itself and the other main cities along the coast like Rabat, Agadir and inland cities like Marrakesh. The NO2 values over countryside and Atlantic sea are much smaller.
