About the Enhancements

HVCT-precip

HVCT false colour creates a false coloured image using the HVC colour model by combining a sensor 1 or 2 (visible/near infrared)
image with a sensor 4 image (thermal infrared). High cold cloud tops are coloured to give an approximate indication of the probability
and intensity of precipitation.

MCIR

Map Coloured IR uses sensor 4 (thermal infrared) to create a false coloured image to colour the sea blue and land green.
High clouds are white and lower clouds are grey.

MCIR-anaglyph

Map Coloured IR 3D image is the same as MCIR but in 3D showing the clouds at different heights above the surface.

MSA

Multispectral Analysis combines a sensor 1 or 2 (visible/near infrared) image with a sensor 4 (thermal infrared) image on daytime
passes and determines which regions are most likely to be cloud, land or sea based on an analysis of the two images.
It produces a vivid, false-coloured image as a result.

Pristine

Pristine images are those received by my system from the satellite without any enhancements, except some normalisation to produce
images which best represent the original data. 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 together with channel B (right) showing sensor 4 (thermal-IR) at all times during normal operation.

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.
