FAQ
NAT to CG4 Conversion
What are NAT files?
NAT is the native archive format of Meteosat Second Generation (MSG), the European weather satellite series operated by EUMETSAT. A file of this type holds one full image of the Earth disk taken by the SEVIRI radiometer, which scans the whole disk every 15 minutes and records it in 12 spectral channels, from visible light to thermal infrared. Eleven of the channels have a ground resolution of about 3 kilometers at the point below the satellite, and the twelfth, a high-resolution visible channel, has 1 kilometer. Such images are the basis of weather forecasting, cloud and fog monitoring, dust and volcanic ash tracking, and climate research. A typical file is named after the satellite and the time of the scan, and it is large, because it holds all the channels together.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
