Contrast (IR) Enhanced: Uses sensors 3 (mid infrared) and 4 (thermal infrared) of the pristine image creating a black and white, contrast enhanced infrared (IR) image showing areas of cloud coverage and layer opacities. Available for both local daylight and night satellite passes.

Map Coloured Infrared (MCIR) with Precip: Uses sensor 4 of the pristine image creating a false colour IR image using a colour lookup table (CLUT) showing areas of cloud coverage, layer opacities with precipitation probability and/or intensity. Available for both local daylight and night passes

NO colour (IR) Enhanced: Uses sensor 4 of the pristine image creating a false colour IR image using a CLUT. Greatly increases contrast in darker (warmer) land/sea regions, and colours (colder) cloud tops providing an indication of their temperatures. Available for both local daylight and night passes.

Multi-Spectral Analysis (MSA) with Precip: Uses sensors 1 (visible light) or 2 (near IR) plus sensor 4 of the pristine image creating a near true colour, near visible light image with precipitation probability and/or intensity using a CLUT. Available only for local daylight passes when solar elevation > 15 degrees.

Sea Surface Temperature (SST): Uses sensors 3 and 4 of the pristine image creating a false colour IR image using a CLUT. Only sea temperatures are imaged so any cloud cover blocking the view is coloured white and land is coloured black (their IR temperatures are ignored). Available for both local daylight and night passes.

Thermal: Uses sensors 3 and 4 of the pristine image creating a false colour IR image using a CLUT. Normally, only cloud tops are imaged, but if no clouds are in the way then land and water surface are imaged. Available for both local daylight and night passes.
