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 10 days by 3 hours steps;
  • Worldwild Cover (0.25°x0.25°).
• Waves data from the FNMOC

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 ≈ 100).
