Israel is currently experiencing a severe drought, including its driest November in 60 years.

After a long period of drought fires broke out on 2 December 2010 in the Mediterranean forest covering the Carmel Mountains south of Haifa. Lasting several days, easterly winds blew the smoke plumes out across the Mediterranean Sea. While the smoke plumes are only visible in daylight, a sizable hot spot is present for most of the time as shown by an animated sequence of images combining the HRV and IR3.9 channels (2 Dec 08:00 UTC–4 Dec 15:00 UTC). The black-and-white HRV images are overlaid with the hottest pixels of the IR3.9 channel in red-to-yellow colours (for values above 307 K).
Prominent smoke plumes are present most of the time over the sea, in particular on 3 December. Looking at their absolute reflection in SEVIRI channels VIS0.6, VIS0.8 and NIR1.6, it steadily decreases with increasing wave length (see images at 8:30 UTC ); between VIS0.6 and NIR1.6 the reflection decreases roughly by a factor of 3. This behaviour points to Rayleigh scattering, typical for smoke. Smoke usually consists of particles with sizes much smaller than the wave length of the observing channels, i.e. in the sub-micron range.
