About the Enhancements

This page shows just several of the 35 enhancements WXtoImg provides:

MSA Multi-Spectral Analysis: combines a sensor 1 or 2 (visible/near infrared) image with a sensor 4 (thermal infrared) image to create a
near true colour, near visible image of the earth.
MCIR-precip Map Coloured IR with Precip: uses sensor 4 (thermal infrared) to create a false coloured image showing areas of likely precipitation.
The likelihood and intensity of precipitation increases as the colour goes from green to yellow to orange to red to black to white.
SST (sea) Sea Surface Temperature: creates a false coloured image using the temperatures from a sensor 4 (thermal infrared) image. The black areas indicate land and cold cloud.
HVCT HVCT false colour: creates a false coloured image by combining a sensor 1 or 2 (visible/near infrared) image with a sensor 4
image (thermal infrared) to create an image in which clouds are tinted by their temperature.
Thermal Thermal: creates a false coloured image using the temperatures from a sensor 4 (thermal infrared) image. Covers the full range of temperatures from very cold cloud tops to hot deserts.
Pristine These are images as they come from the satellite without alteration. The earth appears "upside down" on Northbound passes.
The two images are the two channels sent by the satellite with channel A (left) switching between sensor 1 (visible) or 2 (near-IR)
during the day and sensor 3 (mid-IR) at night and channel B (right) showing sensor 4 (thermal-IR) at all times during
normal operation.
