FAQ
GRIB to CG4 Conversion
What are GRIB files?
GRIB (GRIdded Binary) is the standard format of the World Meteorological Organization (WMO) for weather and climate data laid out on a grid. It was created in 1985 by the WMO Commission for Basic Systems to replace older formats of the Aeronautical Data Format family, and it became the main way for forecasting centers around the world to share the results of their computer models. A file of this type may contain many separate records, each describing one quantity, such as air temperature, wind speed, or rainfall, for a given height and moment in time. The format is compact, which suits the huge volumes of forecast data produced several times a day. It exists in two editions, GRIB1 and GRIB2, and both can appear under the .grib extension.
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.
