Our model data is supplied in a format known as GRIB2 and is a format sponsored by the World Meteorological Organisation (WMO). We now use WMO v27 GRIB standards and have a MO repository for local codes. Please see the glossary for GRIB codes used for each parameter.
GRIB (GRIdded Binary or General Regularly-distributed Information in Binary form) is a concise data format commonly used in meteorology to store historical and forecast weather data.
As GRIB is a binary format an application or viewer is required to represent or visualise the data normally shown overlaying a map.
