> gzip -d gads22a.tar.gzThis will create 3 subdirectories and copy all files in their appropriate places. The tar and gzip programs are also available for DOS (e.g. here). You will need about 3.5 MB of disk space.
> tar -xvf gads22a.tar
If you did already install the software package OPAC (Optical Properties of Aerosols and Clouds), you should install GADS in the same directory, since GADS and OPAC use the same set of optical data of aerosol components, which are stored in the subdirectory optdat.
To use the program gads.f, you must compile it first:
> f77 gads.f -o gadsshould be sufficient. You can now start the program by typing gads. The program has been tested to compile and run under Linux, SunOS, HPUnix, Dec Ultrix, and DOS. Please tell us about any difficulties.

This part of the program contains an endless loop over this table, which can be interrupted by entering 0. Thus you can produce several output files during one program run, which will all be named automatically according to their contents.

in this case, each program run creates one result file, named aererg,
which contains the following optical properties at one wavelength and one
