european-weather-september-2014-captured-by-meteosat

September in Europe started with the remnants of Hurricane "Cristobal", and there were several heavy rain episodes during the month – in Nuremburg, Germany on September 7, in Austria on September 12 and in Sweden on September 21 and 22.

Southern France suffered flooding on September 17 and at the end of the month. Vienna had twice the September average rainfall, while the United Kingdom had its driest start to September for 50 years. 

Fog caused delays at airports such as Amsterdam, Zurich, and Lisbon on September 16, and again on September 18 in Stockholm Arlanda, Leeds, London City, Lisbon, Amsterdam, Istanbul Ataturk, and Zakynthos. 

The autumnal equinox took place early in the hours of September 23 and some areas experienced their first frosts and snow of the autumn. The Balearic Islands had thunderstorms for two days after the equinox, while on September 26, Norway had its first big autumn storm of the year.

The 'Natural Colour RGB' images used in this movie are taken from EUMETSAT's Meteosat-10 satellite in geostationary orbit 36 000 km above the Earth. The Natural Colour RGB product makes use of three solar channels: VIS0.6, VIS0.8 and NIR1.6. In this colour scheme vegetation appears greenish because of its large reflectance in the VIS0.8 channel (the green beam) compared to the NIR1.6 (red beam) and VIS0.6 (blue beam) channels.

Water clouds with small droplets have large reflectance at all three channels and hence appear whitish, while snow and ice clouds appears cyan because ice strongly absorbs in NIR1.6 (no red).

Bare ground appears brown because of the larger reflectance in the NIR1.6 than at VIS0.6, and the ocean appears black because of the low reflectance in all three channels.
