GRB to PGM Conversion
What are GRB files?
GRB is a file extension used for GRIB (GRIdded Binary), a standard of the World Meteorological Organization (WMO) for storing and exchanging weather and climate data on a regular grid. The format is widely used for forecasts from numerical weather prediction models, such as temperature, pressure, wind, humidity, and precipitation. A file of this type is a sequence of messages, and each message holds one set of values for a single parameter, level, and time, together with a description of the grid and the date of the forecast. The format exists in two main editions: GRIB1, introduced around 1990, and the newer GRIB2, which uses the .grb2 or .grib2 extensions. Data are compactly packed, so large forecast archives take little space.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
