Some GrADS Scripts

If you want additional plots, it's not too difficult to generate them yourself.

You need GrADS. The Linux i686 and Ubuntu x86_64 executables should work for most distributions; they are big static executables that don't depend much on your system. Besides the executable you need the data files, containing fonts and geographical maps.

Building from source is badly documented; you'll need supplemental Libraries in specific versions (the executables contain them). The latest Windows version is old; I don't know if my scripts will work with it.

Data are available at NOMADS DODS Servers (here, here, here, here and here). You don't need to download them; they will be accessed online. High resolution GFS data (0.5° lat/lon grid) are contained in directories named gfs_master. The info files of the DODS servers describe the available data and are readable with a normal web browser.

Some variables are "hidden" and prepended by an o. You can use them as well, but be aware that these are averages, sums, maxima or minima that refer to varying time spans. Generally, forecast times at 3, 9, 15, 21, … hours ahead refer to the 3 hours before, while forecast times at 6, 12, 18, 24, … hours ahead refer to the 6 hours before. This is documented in the description of the original GRIB files. The hidden variables just don't appear at the online plot scripts; some of them are redefined to uniform timespans there.

Note that the 0.5° grid is interpolated from the original GFS resolution. Surface data are calculated in a 1152×576 point Gaussian grid (0.3125° zonal resolution). Atmospherical data are calculated using a T382 spherical harmonics model, roughly equivalent in resolution to a 0.5° grid near the equator.

Running the scripts

The scripts are run by commands like gradsdap -lbc "run tmp2m.gs 2008-07-15 06z 24" where tmp2m.gs is the script name, 2008-07-15 06z the initialization date and time (00z, 06z, 12z or 18z; data typically available on DODS servers 6 hours later) of the specific model run and 24 the forecast offset in hours (must be multiples of 3, for correct averages or sums 6; maximum is 180, minimum 0 or 24 for 24 hour values). The scripts aren't very tolerant for input errors.

For older versions of GrADS, use gradsdods instead of gradsdap; if you want to see what's going on, use -lc instead of -lbc. You will get PNG images in the current directory.

Refer to the GrADS documentation if you want to change the scripts. The scripts are in the public domain.
