Note: This guideline does not aim to replace the official installation steps provided by the authors of the OPAC software. We therefore not take any warranty of the correct performance of the OPAC software. For any questions about its installation, it is recommended to contact the corresponding OPAC authors.
- The following instructions are directly extracted and adapted from the official OPAC site -
OPAC consists of ASCII files, which contain the optical properties of cloud and aerosol components and of a FORTRAN program, which allows handling the data. The FORTRAN program was tested to compile and run under DOS (Microsoft Fortran 5.0), Linux (GNU f2c converter), DEC Ultrix, HP Unix, and SunOS. The whole package required about 3.5 MB storage capacity.
The software package v3.1 can be downloaded from the OPAC website (http://www.rascin.net/de/opac_package). This consists on the opac31a.tar file containing the Fortran source code and databases.
This section provides basic instructions for downloading and compiling the OPAC v3.1 aerosol database.
Notice that an upgraded version of OPAC (v4.0) is currently available at http://www.rascin.net/de/opac_40. However, it has not been tested for its integration in ALG v1.2 and its coupling with MODTRAN v5.2. In what follows, this section refers to the installation of OPAC v3.1.
