The latest version (4/2014) had a name change (grib1to2 had been taken), large file support was dropped (not needed with a 64-bit OS) and most importantly installion was made easier by eliminating the need for cnvgrib.
Grib1 to grib2 converter online code#
Variants of the code were written for (1) speed, the (2) large files, (3) ease of updating and/or (4) potential operational usage. POSIX2 environment History is based on code that was written in 12/2009 at CPC and versions of the code are being used at CPC.
gmerge and smallest_grib2, only needed by -fast and -packing c0 (default), supplied in the aux_progs directory of wgrib2. wgrib2 with IPOLATES enabled (-new_grid option). Only simple scan mode options are handled, latlon: we:sn and we:ns, others: we:sn (needs to improved) Requirements are. You need to alter perl script to handle grid before continuing. other grids can be handled if the appropriate grib2 template is supplied. limited to lat-lon, polar stereographic, Lambert conformal, Mercator, and Gaussian grids. Only partial ensemble metadata support. Fast packing option which is optimized for 4-core CPUs Disadvanges are. Complex packing algorithms produce fast-to-read grib2 files which are comparable in size to jpeg2000 packing. Does c0 packing, the smallest of 3 different complex packings. More fields converted than some other solutions. Many repositories include wgrib2 executables wgrib, gmerge and smallest_grib2 are very easy to compile C programs 
Grib1 To Grib2 Converter Currency 1 Maximum file size is not only determined by the file format itself, but operating system/file system capabilities as well.
Easier than some other solutions to compile. This perl script uses wgrib, wgrib2 and a few minor programs that are included with the wgrib2 package (gmerge, smallest_grib2).
