Meteosat Indian Ocean Data Coverage Imagery

The Meteosat Visible and InfraRed Imager (MVIRI) is a high resolution radiometer with three spectral bands. The MVIRI acquires radiance data from the full earth disc during a 25-minute period. This is followed by a five-minute retrace and stabilisation interval, so that one complete set of full earth disc images is available every half-hour. The radiometer operates in three spectral bands:

  MTP IR 11.5 BW Imagery   Infrared 11.5 MVIRI spectral channel over black and white background
The Thermal Infrared (IR) band is used for imaging by day and by night, and also for determining the temperature of cloud tops and of the ocean's surface. This band corresponds to peak re-emission of radiation from the Earth's surface and atmosphere, according to their temperature. As with the VIS band, the atmospheric gases are fairly transparent in this region.

  MTP VIS 0.7 BW Imagery   Visible 0.7 MVIRI spectral channel over black & white background
The Visible (VIS) band (0.45 to 1.0 Ám) is used for imaging during dayight. This band corresponds to peak solar irradiance; furthermore the atmospheric gases are fairly transparent to incoming and outgoing (reflected) solar radiation in this band.

  MTP WV 6.4 BW   Water Vapour 6.4 MVIRI spectral channel over black and white background
The Water Vapour (WV) absorption band (5.7 to 7.1 Ám) is used in determining the amount of water vapour in the upper troposphere. It takes advantage of the strong absorption of emitted terrestrial radiation by atmospheric water vapour. In this spectral region, the atmosphere is very opaque if water vapour is present, but transparent if the air is very dry.
