---|
| 35 | <u>Feedback</u></h3> |
---|
| 36 | We don't get any funding for this project and thus we can't spend much |
---|
| 37 | time for it. But we appreciate any hints about problems with the data set |
---|
| 38 | or suggestions for its improvement, and we will try to discuss and include |
---|
| 39 | them in future versions. Please feel free to <a href="mailto:m.hess@lrz.uni-muenchen.de">send |
---|
| 40 | us an email</a>. |
---|
| 41 | <h3> |
---|
| 42 | <u>Hardware requirements</u></h3> |
---|
| 43 | OPAC consists of ASCII files, which contain the optical properties of cloud |
---|
| 44 | and aerosol components, and of a FORTRAN program, which allows to handle |
---|
| 45 | the data. The FORTRAN program was tested to compile and run under DOS (Microsoft |
---|
| 46 | Fortran 5.0), Linux (GNU f2c converter), DEC Ultrix, HP Unix, and SunOS. |
---|
| 47 | <p>The whole package requires about 3.5 MB storage capacity. |
---|
| 48 | <h3> |
---|
| 49 | <u>Installation</u></h3> |
---|
| 50 | To install OPAC, please extract the archive in an empty directory: |
---|
| 51 | <blockquote>> gzip -d opac31a.tar.gz |
---|
| 52 | <br>> tar -xvf opac31a.tar</blockquote> |
---|
| 53 | This will create 2 subdirectories and copy all files in their appropriate |
---|
| 54 | places. The tar and gzip programs are also available for DOS <a href="http://www.leo.org/komp_prob.html">(e.g. |
---|
| 55 | here)</a>. |
---|
| 56 | <p>If you did already install the <a href="gads.html">Global Aerosol Data |
---|
| 57 | Set (GADS)</a>, you should install OPAC in the same directory, since GADS |
---|
| 58 | and OPAC use the same set of optical data of aerosol components, which |
---|
| 59 | are stored in the subdirectory <b>optdat</b>. |
---|
| 60 | <p>Now the FORTRAN program has to be compiled. On most UNIX computers, |
---|
| 61 | this requires something like: |
---|
| 62 | <blockquote>> f77 opac.f -o opac |
---|
| 63 | <br> </blockquote> |
---|
| 64 | In this case, <b>opac</b> will be the name of the executable file. Some |
---|
| 65 | compilers give warning errors, which may be ignored. If you want to use |
---|
| 66 | a DOS computer, you must comment out lines 505-507 instead of 501-503 in |
---|
| 67 | opac.f. The "\" character is not understood by all compilers. |
---|
| 68 | <br> |
---|
| 69 | <br> |
---|
| 70 | <h3> |
---|
| 71 | <u>The following files belong to OPAC:</u></h3> |
---|
| 72 | |
---|
| 73 | <ul> |
---|
| 74 | <li> |
---|
| 75 | The optical properties of the clouds and of the 10 aerosol components, |
---|
| 76 | for up to 8 relative humidities and 61 wavelengths are stored in the subdirectory |
---|
| 77 | <b>optdat</b>. |
---|
| 78 | Each cloud or aerosol component has up to 8 files (for the humidity classes), |
---|
| 79 | each containing data for all 61 wavelengths. The filename consists of a |
---|
| 80 | 4 letter approximation for the cloud or the aerosol component, combined |
---|
| 81 | with the relative humidity, for which the optical properties have been |
---|
| 82 | calculated. For clouds only 1 file exists, which is attributed to 0% humidity, |
---|
| 83 | indicating that there is no dependence of size distribution with relative |
---|
| 84 | humidity taken into account.</li> |

| 551 | <b>input:</b> Each input file for opac.f, which contains data and parameters |

| 552 | to be extracted from OPAC must be stored in a file in this directory. The |
---|
| 553 | program prompts you for the filename and automatically appends the extension |
---|
| 554 | ".inp". As an example, the file <a href="opac.inp" <B>opac.inp</a> is provided.</li> |

| 562 | <h3> |
---|
| 563 | <u>Using the program</u></h3> |
---|
| 564 | The purpose of the program is to mix optical properties of single cloud |
---|
| 565 | or aerosol components (stored for 1 particle/cm^3) to optical properties |
---|
| 566 | of clouds or aerosol types, which may consist of several components. It |
---|
| 567 | is also possible to calculate optical properties which are not stored in |
---|
| 568 | the data base. These are for instance the optical depth, the extinction |
---|
| 569 | ratio (extinction coefficient divided by mass), or quantities which are |
---|
| 570 | integrated over the solar or terrestrial wavelength range. |
---|
| 571 | <p>Before starting the program, you have to edit an input file in order |
---|
| 572 | to define, which information you want to extract and calculate from the |
---|
| 573 | data base. Since the program prompts you for the name of the input file, |
---|
| 574 | you can use copies of the example and default input file <a href="opac.inp" <B>opac.inp</a>. |
---|
| 575 | <p>The program is started by typing <b>opac</b> in the subdirectory |
---|
| 576 | <b>opac31</b>, |
---|
| 577 | if you used the compiler command shown above. |
---|
| 578 | <p>The results are stored in the subdirectory <b>result</b> in files, whose |
---|
| 579 | names consist of the input file name, but with the extension <b>.inp</b> |
---|
| 580 | replaced by <b>.out</b>. |
---|
| 581 | <p>If you have the feeling, that the instructions given in this file, together |
---|
| 582 | with the explanations in the OPAC paper <i><a href="../mitarb/heko97.html">(Hess |
