High clouds, sea, mountains, forests

June 20, 1998 13:59 UTCSouth-west of France by a heat day of June. On the infra-red image, the hot ground (1) appears very dark whereas the sea (2), colder, is brighter. In bottom of the image, the Pyrenees (3) are also brighter than the plain because the ground is less hot. On the visible image, the sea (4) is darker than the land (5), because it absorbs more the solar radiation. In the same way, the Landes forest (6) appears darker than the surrounding areas. Clouds over the sea (7) are white on the infra-red image. That means they are cold, and thus they are high clouds. On the visible image, these clouds are not easy to see: they are thin clouds. They are probably cirrus.

Cold fronts, showers, land - sea contrasts

June 5, 1999 08:15 UTCA cold front (1) has just passed over the North-West of France. Behind, the sky is almost clear. The shade of the cloudy strip appears on the visible image. A secondary cold front (2) approaches Brittany. Thermal contrast is more significant: there are many shower clouds (3) behind this secondary front. The sea (4) does not differ from the land (5) on the infra-red image: their respective temperatures should be nearly the same. On the other hand, on the visible image, the sea (4) is much darker than the land (5), because it does not reflect the solar radiation as the land does.

Eruption of Etna, Sicily

July 28, 2001 05:06 UTCSicily. The plume of smoke (1) from the eruption of Etna is pushed by a northwest wind. On the visible image, the shade of the plume covers the volcano. On the infrared image, a black zone, thus a warm one, is visible in the volcano crater area. Lipari islands (2) are also visible in the north of Sicily.
