- Display of atmospheric sounding forecast on thermodynamic diagrams SkewT-LogP.
- Waves : height, direction, period, whitecap probability, for wind waves, swell, and for significant, maximum, primary, secondary waves.
- Sea current (not provided by the zyGrib's data server)
Automatic Meteo data download
Specific GRIB files created by and for zyGrib;
- from NOAA (GFS Model);
  - Updates every 6 hours (depends on NOAA data availability);
  - Forecast up to 8 days by 3 hours steps;
  - Worldwild Cover (0.5°x0.5°).
- from Meteoblue (numerical mesoscale models (NMM)
  - Updates every 12 hours;
  - Forecast up to 3 days by 1 hours steps;
  - Switzerland and surroundings: exactly 44N 003E - 50N 003E - 50N 014E 44N 003E
  - High resolution : 300x300 km = 100x100 dots.
- Waves data from the FNMOC
  - Global model: grid 1°x1°, forecast up to 7 days: the world's oceans.
  - Local model: grid 0.2°x0.2°, forecast up to 3 days: Mediterranean Sea, Black Sea, NE Atlantic Ocean around Europe, Baltic Sea,
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 PSKmail (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 GSHHS (Precision ≈ 100m ) (For quicker display, use of RANGS maps adapted by Rainer Feistel).

High resolution world maps and additional cities lists

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
    - gshhs : world maps GSHHS
  - tr : translations
- grib : GRIB files
- src : sources of zyGrib (some libraries are included here)

Sources
- zyGrib-6.1.4.tgz (13.8 Mo)
Compilation is needed. In a terminal window, unpack the archive file (tar xvzf zyGrib-6.1.4.tgz). Move to zyGrib repository and run command "make" auf. That's all ... Normally ;-)
Warning
- QT4 and QWT should be installed (at least version 6.0.0).
- 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 ...

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:
    make install
    ln -s /usr/local/qwt-x.x.x/ /usr/local/qwt6
    create a file: /etc/ld.so.conf.d/qwt6.conf containing only 1 line: /usr/local/qwt6/lib/
    ldconfig
- compile zyGrib
  - cd zyGrib-xxxxx
  - make
  - make install
- command to run zyGrib from a terminal: cd ~/zyGrib; ./zyGrib

Compiled version for Ubuntu
See for configuration of repositories
High resolution Worldmaps :
- gshhs_maps2_cities_deb_install (1.5 ko)
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).
Do not modify the structure of repositories. Run zyGrib.exe, it's all.
- zyGrib_win-6.1.4.tgz (21 Mo)
- With high resolution maps: zyGrib_win_withmaps2-6.1.4.tgz (121.8 Mo)
It is of course also possible to compile sources under Windows, after having QT4 installed. QT4 (version included in Mingw compiler is perfect).

Mac OS X version (Intel)
Ready to use complete build:
- zyGrib_mac-6.1.4.dmg (25.5 Mo)
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:
    - make veryclean
    - make mac

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)

* Files come with zyGrib.
Loading a lot of cities can slow the program start.
