WGRIB is a program to manipulate, inventory and decode GRIB files.The program is known to work on machines ranging from 486s to Cray supercomputers. (One fellow even ported it to a 286!)The program is Y2K friendly (NCO Y2K testing procedure).

wgrib is an operational NCEP program and has been usedin production for many years.
- iGrib is a GRIB (GRIdded Binary) file viewer for iOS (iPad, iPhone and iPod Touch). This allows you to see the same data that the professionals use for forecasting. This app is particularly valuable for people like sailors who require a longer range forecast. (The author is a sailor) Grib files.
- Download FREE GRIB Files. The following is a list of supported regions. Click on the KEY to download a compressed 7 day wind forecast for the selected region. NOTE: Internet Explorer users will need to right click the appropriate link and select “Save Target As.” to download the file. To view GRIB files you will need the following.
- GRIB Explorer for Mac is a 100% Mac native application that is both elegant and intuitive while supporting an unparalleled number of GRIB data – more than any other viewer on the market. These data are displayed in gorgeous full color interactive maps dynamically displaying the weather data of interest to you.

What is PredictWind Offshore Weather for Mac. PredictWind Offshore Weather is powered by PredictWind's world leading marine weather forecasts, the free offshore app allows seamless downloading of multiple GRIB files for your coastal or offshore passage. The intuitive interface allows you to download and immediately view GRIB files, weather.
Highlights for v1.8.x:
- Support for simple-packed spectral data (Luis Kornblueh). Note: you still need spectral -> grid routines.
- Cleanup of triangular grid support (Luis Kornblueh)
- New and improved tables
- More grid information, including scanning mode
- fixed bug in grid vs earth relative north (-v option only)
Highlights for v1.7.x:
- scans entire file for grib messages (D. Haalman)
- Added German Weather Service (DWD) tables 201, 202, 203 and 2
Support for triangular grid (Helmut P. Frank) - fractional mb (NCEP local extension)
- added new levels
- updated NCEP operational GRIB table
- fixed thinned grids with bitmap
- NCEP ensemble support
- fixed -H option
- Support for the 3/6/12 hour forecast time units
- Fixed a bug with bitmap when the precision is greater than 24 bits. This is more of a theoretical problem as most people (NCEP and ECMWF) limit the precision to 16 bits and I can't imagine anyone using more than 24 bit of precision for any meteorological data. Thanks LB for finding the bug.
- Source code in a tar file. For people who want to read the source code before it is combined into wgrib.c.
- more time codes like SECONDS
- New or updated ECMWF grib tables: 128 129 130 131 140 150 160 170 180
Highlights for v1.6.x:
- fixed a problem with identifying 1997 Reanalysis files.
- fixed a problem with the GDS header in the -H option
- optional binary output of PDS and GDS (-H option)
- -d all (decode entire file)
- thinned grid support
- fix of my mis-interpretation on how year 2000 is stored in GRIB
- NCEP operational table
- updated documentation
Under testing:
Note: there were two definitions for SNOC and CWAT in the operationaland Reanalysis grib tables. For the time being, I'm calling snow cover'SNOWC' and canopy water 'CNWAT.'

Grib File Viewer For Mac
- C source code Netscape: shift+left_mouse_button, (If your browser alters the code, use anonymous ftp to download /pub/wgrib/wgrib.c)
- ftp://ftp.cpc.ncep.noaa.gov/wd51we/wgrib (FTP access: documentation, test files, etc.)
- wgrib.tar See above for source code. (For people who want to read or re-use the source code.)
Compiled versions:
Free Grib File Viewer
- not all links are valid and compiled versions tend to be older versions
- MS-DOS (compiled with gcc)
- Windows (compiled with gcc/cygwin)
- Windows 64-bit (compiled with gcc/cygwin 64)
Windows: find vs. grep and egrep
You should use grep or egrep instead of the MS-DOS 'find' command.
The (e)grep command is more flexible and it is consistent with the
documentation. Public domain versions exist for ms-dos, windows and
Win32 machines. Personally I would look for a grep based on GNU source
code. In your favorite internet search engine look for '+grep +gnu +windows'.
2 GB limit, 32 vs 64 bit computers:
Wgrib is limited to 2 GB files when used on 32-bit machines suchas a pentium-4. (2 GB is the maximum value of a 32-bit integer.)On 64-bit machines, the 2 gig limit is replaced by a really big number.
