The major differences are in the structure of the messages. Collections of GRIB messages can be appended to each other.Ĭurrently, there are two different coding standards: GRIB edition 1 and GRIB edition 2. Each message contains several sections:Įach message stands alone as meaningful data so a file may contain one or more GRIB messages. GRIB files are a collection of self-defining messages. On the other hand, this type of format provides faster access to the data and uses less memory than a plain text format. How to read a GRIB file?Ī binary file has its information stored in ones and zeros, which means if we try to open the file with a text editor such as Notepad we won’t be able to read any information. GRIB files are machine-independent and require software for encoding and decoding. GRIB files were designed to exchange and store large volumes of gridded data and are used in Numerical Prediction models such as Weather Research Forecast (WRF) model, in reanalysis data (ERA5 and CFSR), and in forecast data, such as the NOOA Global Forecast System (GFS) or the ECMWF Integrated Forecasting System (IFS). It was first defined in 1985 by the World Meteorological Organization (WMO). It is a data format used in meteorology to store weather data. GRIB stands for General Regularly-distributed Infomation in Binary form.
