Meteorological data import

The following scripts and functions are used to control the download of meteorological input data and boundary conditions for the MM5 prognostic meteorological model.

The data are uploaded daily from MET DATA SOURCE

Data collection strategy

After downloading a file, its size is checked. When it is smaller than the expected size, download is tried again. The script now tries it 3 times for each file. If the third try fails as well, the file is inserted into the "RETRY list".

When the first round of downloads is finished, the script tries again to download the files listed in the "RETRY list" (maximal 3 times each).

In case the file is still missing/corrupted, it is substituted by yesterdays file (if available).

The download procedure, success and errors, are logeon the system STATUSBOARD.

    /app/data/gfs/get_gfs.phpdownloads gfs data, scheduled by cron
    /app/data/gfs/ungrib_gfs.shungribs gfs data calling
    /app/data/gfs/wget_fnl.shdownloads (historical) fnl data, on demand
    /app/data/gfs/ungrib_fnl.shungribs fnl data calling
    /app/data/pregid/pregrid_gfs.shreads gfs grib data for forecast
    /app/data/pregid/pregrid_fnl.shreads fnl grib data for historical scenarios

    For MM5 model runs, the main path is /app/mm5/mm5_location/:
