El Nino Phenomenon
(Date of photograph unknown)
Earth's 3-D cloud cover. Coloured composite image of the Earth, showing surface temperature (various colours) and three-dimensional (3-D) cloud cover (white). It was created by integrating multiple satellite data, and is the first representation of the Earth's cloud cover in three dimensions. It combines electromagnetic, spectroscopic and thermal measurements of cloud cover and land and sea temperatures. Temperature is colour-coded, from red (high) through to dark blue (low). The warm water current of El Nino in the Pacific Ocean is clearly seen (red band at centre). Red areas seen on the land masses of North and South America (green/brown) represent forest fires.
