What is a .GRIB2 file?
GRIB2 is the second-generation GRIB format for weather and climate data.
- Did you know
- GRIB2 added more flexibility and better compression to the original GRIB standard.
- GRIB2 specifies coordinates in micro-degrees rather than the milli-degrees of GRIB1, giving far finer geographic precision.
- GRIB2 became the World Meteorological Organization’s official format, and a successor GRIB3 edition is now under discussion.
- 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
- .GRIB2 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 .GRIB2 file
- Drag a .GRIB2 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.
