These two Medium Resolution Imaging Spectrometer (MERIS) images, show a before and after scenario of the effects of forest fires in Kazakhstan. The top image is from August and is shown in simulated true color (MERIS bands 7,5,2) it shows clearly blue smoke plumes from fires particularly on the eastern side of the image, the plumes all fanning out in a north-westerly direction. There are also some higher atmosphere smoke plumes extending down the center of the image that appear to be blowing in a north - south direction, the source of these plumes are likely to be fires off to the north of this image. The bottom image is from later in the year, in October. The bands chosen for this image were down so to highlight spectral differences over land (MERIS bands 15,13,9). If we look at the same areas that were the source of fires in the top image we can see dark brown patches which represent scar patches of where forest once was...
