GRIB (GRIdded Binary) is a concise data format commonly used in meteorology to store and exchange gridded data, such as weather forecasts and climate model outputs. It is designed for efficient storage and transmission of large datasets. GRIB files contain numerical data representing various atmospheric parameters (temperature, pressure, wind speed, humidity, etc.) at specific grid points covering a geographical area. The data is typically encoded in binary format to minimize file size. GRIB is widely used by weather agencies, research institutions, and other organizations involved in weather forecasting and climate modeling. The format supports various grid types, including regular latitude-longitude grids, Gaussian grids, and unstructured grids. GRIB files also contain metadata describing the data, such as the parameter being represented, the level (e.g., pressure level), the valid time, and the grid definition. There are two main versions of GRIB: GRIB1 and GRIB2. GRIB2 is the newer version and offers improved compression, more flexible grid definitions, and support for a wider range of parameters.
