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

Fires in central Russia are burning for almost two months now. These satellite images from August 4, 2016 show fire, smoke and its impact on atmospheric aerosol loading and air quality in the region. The Aerosol Optical Depth (AOD) is a measure of particle loading in the atmosphere, which reaches as high as 2-3 on this day, which indicates very high loading of PM2.5 in the air. Another air quality indicator and emission from fires is carbon monoxide (CO) gas showing very high concentration in the satellite image.

Deonar dump fire in Mumbai that started sometime on January 27-28 still putting out smoke and making air toxic for breathing. The different part of the city has been experiencing smog and hazardous air quality. The change in the wind direction spreading the smoke for fires in different part of the city. NASA/NOAA satellite VIIRS images (top panels) from Jan 27-31, 2016 clearly show a wide spread of smoke from this fires. NASA’s high-resolution satellite LANDSAT on January 28, 2016, also capture the fires and smoke (bottom panel).
