Suomi NPP VIIRS (above; toggle with Google maps) and Aqua MODIS (below; toggle with Google maps) true-color Red/Green/Blue (RGB) images visualized using SSEC RealEarth showed 2 smoke plumes from wildfires burning in Greece on 17 July 2015. These fires were causing evacuations in some areas, according to the Wildfire Today site.

Surface observations around the time of the images (below) indicated that air temperatures were in the 90-100º F (32.2-37.8º C) range at many sites across the region. Winds at Athens were from the northeast at 26 knots, with gusts to 36 knots (time series plot of surface data). Near the edge of the larger smoke plume to the southwest, the surface visibility was restricted to 5 miles at Kithira (but was as low as 3 miles at 10 UTC: time series plot of surface data).

EUMETSAT Meteosat-10 High Resolution Visible (0.8 µm) and shortwave IR (3.92 µm) images (below; click to play animation; also available as an MP4 movie file) showed thee temporal evolution of the smoke plume and the associated fire hot spots (dark black to red pixels). Athens is located within the cyan circle on the images.
