NOTE:
NOAA-19 can be interfered with by METEOR-M2 because they share the same frequency and their orbits overlap several times a day. NOAA-15 is 24 years old (as of 2022) and can get "cranky", but it has been brought back to "life" more than once by satellite ground control engineers. NOAA predicted that only one analog APT "bird" would be operating by the 2020's so three new digital LRIT Russian METEOR birds were sent to replace them except no one "told" NOAA-15, 18 and 19! They refuse to "die" and are still working 24/7 while two of three METEORs have failed!
Map Coloured Infrared (MCIR) with Precip:
Uses sensor 4 (thermal infrared) of pristine image creating a false colour image using colour lookup table (CLUT) showing areas of cloud coverage, layer opacities with precipitation estimates ranging in colours from light (green), moderate (yellow), strong(red), intense (grey) to extreme (black). Available for both local daylight and night passes.
Multi-Spectral Analysis (MSA) with Precip:
Uses sensors 1 or 2 (visible light or near infrared) and sensor 4 of pristine image creating a near true colour near visible light image with precipitation estimates ranging in colours from light (green), moderate (yellow), strong(red), intense (grey) to extreme (black). Available only for local daylight passes when solar elevation > 15 degrees.
MSA anaglyph (false 3D image):
Uses sensors 2 and 4 of pristine image and determines which regions are most likely cloud, land or sea based on an analysis of the two images creating a stereoscopic photograph (anaglyph) producing a false three-dimensional image when viewed through red/blue 3D glasses. Available only for local daylight passes when solar elevation > 15 degrees.
Sea Surface Temperature (SST):
Uses sensors 3 (mid infrared) and 4 of pristine image creating a false colour image using a CLUT. Normally, only cloud tops are imaged, but if no clouds are in the way then water surfaces are imaged. Available for both local daylight and night passes.
Thermal:
Uses sensors 3 and 4 of pristine image creating a false colour image using a CLUT. Normally, only cloud tops are imaged but if no clouds are in the way then land and water surfaces are imaged. Available for both local daylight and night passes.
