- Automatic Meteo data download
Specific GRIB files created by and for zyGrib;
- from NOAA
- Updates every 6 hours (depends on NOAA data availability);
- Forecast up to 10 days by 3 hours steps;

- Automatic Download from IAC (fleetcode) Data
- Weather Data from NOAA;
- Analysis and 24 hours Forecast, only for Europa and North Atlantic (pressure, isobar and fronts);
- Daily four times update;
- IAC (International Analysis Codem, fleetcode) files are very small and can be used with
(For any questions, please refer directly to PSKMail conceptors; I don't know anything about it).
- Raw or compressed GRIB Data (gzip *.gz; bzip2 *.bz2) can be used
- Bottom Worldmap Layer from

All files must be in the same repository.
General structure :
- zyGrib : main directory
- data : software data
- config : configuration files
- fonts : fonts
- gis : countries and cities
- img : images for graphical interface
- maps : maps
- tr : translations
- grib : GRIB files
- src : sources of zyGrib (some libraries are included here)
- Instructions de compilation sous Debian
- apt-get install build-essential libqt4-dev libbz2-dev zlib1g-dev libproj-dev libnova-dev
- install qwt (version >= 6.0.0)
- download the last version on the qwt project page
- unzip qwt-x.x.x.zip (replace x.x.x by your qwt version)
- cd qwt-x.x.x
- qmake; make
- run as root:
ln -s /usr/local/qwt-x.x.x/ /usr/local/qwt6
create a file:
containing only 1 line:
- compile zyGrib
- cd zyGrib-xxxxx
- make install
- command to run zyGrib from a terminal:
cd ~/zyGrib; ./zyGrib
- Compiled version for Ubuntu
configuration of repositories
High resolution Worldmaps :
The script gshhs_maps2_cities_deb_install allow
to download and install high resolution Worldmaps which are not
in the main package in /opt/zyGrib/maps/gshhs
and more cities in /opt/zyGrib/data/gis
Script and packages by Dominique Hausser.
- Windows version
QT4 dll's included
Just unarchive where you will, (for eg. Desktop, home repository, USB flash drive, memory stick).
It is of course also possible to compile sources under Windows, after having QT4 installed.
(version included in Mingw compiler is perfect).
Do not modify the structure of repositories.
Run zyGrib.exe, it's all.
- Mac OS X version (Intel)
Ready to use complete build:
- Mac version (PPC)
zyGrib must be compiled for your computer.
- Install the Apple development tools
and the libraries needed by zyGrib
(ask the forum for more precise instructions)
- Install XCode
- Install MacPorts
- Open a terminal and enter:
- sudo port install qt4-mac qwt-60 proj libnova zlib bzip2
- Download and uncompress zyGrib for Linux (sources)
- In a terminal, from zyGrib directory:
High resolution world maps GSHHS
The main package comes with 3 Resolutions (≈25 km, ≈5 km and ≈1 km).
You can add higher resolution maps (≈200 m and ≈100 m).
Be careful with low speed connection (due to the size of the archive).
Unpack maps in <...>zyGrib/maps/gshhs.
You don't need them, but it is so much nicer ...
Linux, Windows : zyGrib_maps2.4.tgz (100.8 Mo)
Mac OS X (Intel/PPC) : zyGrib_maps2.4_mac.dmg (103.1 Mo)
Additional cities lists
Data extracted from the database GeoNames
To be copied in directory
* Files come with zyGrib.
Loading a lot of cities can slow the program start.
