The program grib2v5d converts the content of a GRIB file (a format used
for exchanging meteorological model fields) into a file that can be viewed
with Vis5d, a popular program for 3-D visualisation of meteorological fields.
The vertical level types supported on input are sigma, eta (Mesinger),
(some kind of) hybrid sigma/pressure, height and pressure. The fields can
be interpolated, on output, at height levels (interpolation to pressure
levels may be added in the future), or can be kept at the same levels as
in input (this is especially useful for viewing data at model levels without
the filter of interpolation). The horizontal grid should be regular lon/lat,
either rotated or not; no horizontal interpolation is made since Vis5d
supports directly this type of grid. The program is mainly written in fortran
90 and is derived from a previous version made by Paolo Patruno; it makes
use of a Fortran77 library for managing access to grib files, a C library
for reading and decoding grib and a C subroutine (modified from the one
provided with Vis5d) for writing topography files. The program has been
developed at ARPA-SIMC (Regional
hydro-meteorological service of Emilia Romagna, Italy) in the framework of the
(Consortium for Small scale MOdelling) consortium which includes, among its
participants, German, Greek, Italian, Polish, Romanian, Ruassian and Swiss meteorological Services.
Grib2v5d version 2.5 has been released, it has no new features
but mainly bug fixes and a GNU-autotools build system that makes it much
easier to build, also reducing the external dependencies.
for Grib2v5d (almost completely up-to-date) in html format is available
on this site
I have released readglobe,
a converter for topographic data from the global 1 Km elevation dataset
Globe (available at
to the Vis5d topography format. You can download the sources at sourceforge.
You can download Grib2v5d at sourceforge.
Remember also to download the required package
package is required only for older versions of grib2v5d, starting from version 2.5 it is not required anymore.
Enjoy your gribs on Vis5d!
