This perl script uses wgrib, wgrib2 and a few minor programs that are included with the wgrib2 package (gmerge, smallest_grib2).

Here are some of the advantages of grb1to2.pl, • Easier than some other solutions to compile. Many repositories include wgrib2 executables wgrib, gmerge and smallest_grib2 are very easy to compile C programs • More fields converted than some other solutions. Easy to modify code for new fields. • Does c0 packing, the smallest of 3 different complex packings. • Complex packing algorithms produce fast-to-read grib2 files which are comparable in size to jpeg2000 packing. • Fast packing option which is optimized for 4-core CPUs Disadvanges are • Only partial ensemble metadata support • POSIX required • limited to lat-lon, polar stereographic, Lambert conformal, Mercator, and Gaussian grids • other grids can be handled if the appropriate grib2 template is supplied.

Drivers Gemini First Mix Drivers. • Does not convert from grib2 to grib1. • Quits when finds a problem grid. You need to alter perl script to handle grid before continuing. • Only simple scan mode options are handled, latlon: we:sn and we:ns, others: we:sn (needs to improved) Requirements are • wgrib2 with IPOLATES enabled (-new_grid option) • wgrib • gmerge and smallest_grib2, only needed by -fast and -packing c0 (default), supplied in the aux_progs directory of wgrib2 • perl • POSIX2 environment History Grb1to2.pl is based on code that was written in 12/2009 at CPC and versions of the code are being used at CPC. Variants of the code were written for (1) speed, the (2) large files, (3) ease of updating and/or (4) potential operational usage.

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. This version retains radius of the earth from the grib1 file unlike the previous versions. Nissan Connect Sd Map Update Torrent.
