Grib display and download from many sources is free. Expedition – Expedition is the Sailing navigation and weather application.ATMOGRAPH ModelVis Commercial numerical weather model data visualization software capable of decoding and displaying both GRIB 1 and GRIB 2 data formats.These range from command line utilities to graphical visualisation packages. This information includes spectral (harmonics of divergence and vorticity) vs gridded data (Gaussian, X-Y grid), horizontal resolution, and the location of the origin.Ī number of application software packages have been written which make use of GRIB files. If a description of the spatial organization of the data is needed, the GDS must be included as well. The PDS describes who created the data (the research / operation center), the involved numerical model / process (can be NWP or GCM), the data that is actually stored (such as wind, temperature, ozone concentration etc.), units of the data (meters, pressure etc.), vertical system of the data (constant height, constant pressure, constant potential temperature), and the time stamp. There are 2 parts of the GRIB 1 header - one mandatory (Product Definition Section - PDS) and one optional (Grid Description Section - GDS). No machine-readable versions of the WMO tables (now available for GRIB-2, but not GRIB-1).
The data in GRIB-1 are typically converted to integers using scale and offset, and then bit-packed. So collections of GRIB records can be appended to each other or the records separated.Įach GRIB record has two components - the part that describes the record (the header), and the actual binary data itself. GRIB files are a collection of self-contained records of 2D data, and the individual records stand alone as meaningful data, with no references to other records or to an overall schema.
