NCEPLIBS-grib_util

This is a collection of NCEP GRIB related utilities, for GRIB1 and GRIB2.

GRIdded Binary or General Regularly-distributed Information in Binary form (GRIB) is a data format for meteorological and forecast data, standardized by the World Meteorological Organization (WMO). GRIB edition 1 was approved by the WMO Working Group on Data Management (WGDM) in 1994. GRIB edition 2 (GRIB2) was approved by the WGDM in 2003.

This is part of the NCEPLIBS project.

For more information see the NCEPLIBS-grib_util documentation and the NCEP WMO GRIB2 Documentation.

To submit bug reports, feature requests, or other code-related issues including installation and usage questions, please create a GitHub issue. For general NCEPLIBS inquiries, contact Edward Hartnett (secondary point of contact Alex Richert).
