  • Potential Temperature min - max 2 m above mean sea level
  • Relative Humidity 2 m above mean sea level
  • Total Precipitation (mm/h)
  • Total Cloud Cover (%)
  • Dew Point 2 m above mean sea level
  • 0C Isotherm
  • Snow (Depth - Risk)
  • CAPE (convective available potential energy) at earth level.
  • Data in altitude (850, 700, 500, 300, 200 hPa) : geopotential altitude, wind, temperature, theta-e, relative humidity.
• Automatic GRIB data download
  • Meteo Data from NOAA (GFS Model);
  • Specific GRIB files created by and for zyGrib;
  • Updates every 6 hours (depends on NOAA data availability);
  • Forecast up to 7 days by 3 hours steps;

• Raw or compressed GRIB Data (gzip *.gz; bzip2 *.bz2) can be used
• Bottom Worldmap Layer from GSHHS (Precision ≈ 100m ) (For quicker display, use of RANGS maps adapted by Rainer Feistel).

Software

• zyGrib Software is distributed under GNU GPL v3
• QT4 graphical environment
• zlib data compression
• bzip2 data compression
• Checksum sha1
• Map projection proj.4

zyGrib is developed under Linux and for Linux. Anyhow a windows version has been compiled for those, for any real or virtual reason, still under windows.

 

For a MacOS version, compile sources with the port qt4-mac via macport.

  • tr : Translations

Packages for Ubuntu and Debian
Packages for openSUSE
Mandriva repository
Windows version
World maps

• Sources
  • zyGrib-3.9.2.tgz (15841 ko)
  Compilation is needed. In a terminal window, unpack the archive file (tar xfzv zyGrib-3.9.2.tgz). Move to zyGrib repository and run command "make" auf. That's all ... Normally ;-)

  For Mac OS X : Sources have to compiled with qt4-mac via macports.

  Attention

  • QT4 must be installed.
  • If you have more than one QT version installed, you have to use "QT4 qmake". You just do it in changing Makefile first line (found in src repository) in adjusting QTBIN variable.

  Under Linux you could of course use the windows compiled version with wine, but ...

• Compiled version for Ubuntu and Debian

  See for configuration of repositories

  High resolution Worldmaps :

  • gshhs_maps2_deb_install (1 ko)
  The script gshhs_maps2_deb_install allow to download and install high resolution Worldmaps which are not in the main package in /opt/zyGrib/maps/gshhs

  Script and packages by Dominique Hausser.

• OpenSuse repository by bkw

• Mandriva repository by jgranger

• Version Windows

  
  QT4 dll's included

  Just unarchive where you will, (for eg. Desktop, home repository) Do not modify the structure of repositories. Run zyGrib.exe.

  • zyGrib_win-3.9.2.tgz (20211 ko)
  It is of course also possible to compile sources under Windows, after having QT4 installed. QT4 (version included in mingw Compiler is perfect).

Worldmaps GSHHS

The main package comes with 3 Resolutions (≈25 km, ≈5 km und ≈1 km). You can add higher resolution maps (≈200 m und ≈100 m). Be careful with low speed connexion (due to the size of the archive).

Unpack maps in <...>zyGrib/maps/gshhs.

You don't need them, but it is so nicer ...

• zyGrib_maps2.tgz (103258 ko)
