Fire, smoke and air quality in Portugal

Series of images taken by NOAA’s NPP VIIRS satellite over Portugal and northern Spain showing progression of fires in the region. There were no fires on August 5th. Small fires (red dots on the image) started appearing on August 6th and quickly spreading all over the region. In general this region observe good air quality conditions with observed AODs on August 5th are less than 0.1. As fire started spreading in the larger region, air quality quickly became poor with AOD values as high as 1.0 (even higher in some areas). The impact on air quality over populated area still remains minimal due to prevailing wind directions, which transported most of the smoke over ocean. Read more on these fires at BBC
