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 atmospheric variables (temperature, pressure, wind speed, etc.) at specific locations and times. The data is organized on a grid, which can be regular or irregular, and the format includes metadata describing the grid, the variables, and the time period covered. GRIB is particularly well-suited for archiving and distributing weather data due to its compression capabilities and self-describing nature. Different versions of the GRIB standard exist (GRIB1 and GRIB2), with GRIB2 offering improved compression and support for more complex data structures. The format is widely supported by meteorological software and is essential for weather forecasting, climate research, and other applications that rely on gridded weather data.
