NOAA APT weather satellite images recorded by VA3ROM at Thunder Bay, Ontario, Canada.


Coordinates (latitude, longitude): 48.453, -89.210 (Grid: EN58jk)
Receiver: RTL-SDR USB dongle
Antenna : Reactive turnstile (Ch. 5, Modern Antenna Design) with LNA

Thermal: Uses sensors 3 (mid infrared) and 4 (thermal infrared) of the pristine image creating a false colour image of the earth using a colour lookup table (CLUT). Normally, only cloud tops are imaged but if no clouds are in the way, the earth's surface (land and water) is imaged. Available for both local daylight and night time satellite passes.

Sea Surface Temperature (SST): Uses sensors 3 and 4 of the pristine image creating a false colour image of the earth using a CLUT. Normally, only cloud tops are imaged, but if no clouds are in the way, water surfaces are imaged. Available for both local daylight and night time satellite passes.

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

Multi-Spectral Analysis (MSA) with Precipitation:
Uses sensors 1 or 2 (visible light or near infrared) and sensor 4 of the pristine image creating a near near true colour, near visible light image of the earth with precipitation probability and/or intensity using a CLUT. Available only for local daylight satellite passes.

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