What is a .GRIB file?
GRIB stores weather and climate model output. Used by meteorological agencies worldwide.
- Did you know
- GRIB is the World Meteorological Organization’s standard for sharing forecast data.
- GRIB was created by the World Meteorological Organization’s Commission for Basic Systems, with the first edition introduced in the mid-1980s.
- GRIB2, the second-edition format, became the WMO’s official exchange standard and added template-based descriptions and better compression.
- What Analyser reads
- Inspect geospatial and GIS files without a map: TopoJSON, OpenStreetMap XML, Esri Shapefile siblings (SHP/SHX/DBF/PRJ/CPG), world files, GML, NMEA GPS logs, IGC flight logs, MapInfo TAB/MIF, GDAL VRT, PMTiles, DTED terrain, Esri ASCII grids and SRTM .hgt - surfacing CRS/EPSG, feature/record counts, bounding boxes and elevation ranges. GRIB/NetCDF/GeoPackage/MBTiles/MrSID/ECW identified.
- Depth of analysis
- .GRIB is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .GRIB file
- Drag a .GRIB file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
