Figure 2.1: Directory structure of SCIATRAN Version 1.2

Directory VERSION1.2/Execute/ contains the main Makefile. The executable file can be created or updated during installation or after program modification by invoking GNU Make (type: make (depending on your system environment)) in directory VERSION1.2/Execute/. The Makefile automatically generates the appropriate executables for SUN, IMB, or CRAY using the system VENDOR variable.

Note that the Makefile only reflects the ife/iup environment. Therefore, modifications might be necessary if SCIATRAN has to be installed in a different environment.

GNU Make is a tool which controls the generation of executables and other non-source files of a program from the program's source files. You can get it at the GNU Project - Free Software Foundation Page.

GNU Make evaluates the environment variable VENDOR in order to determine the local host type (IBM, SUN, or CRAY). The executable name depends on the host type (SCIATRAN_IBM.exe, SCIATRAN_SUN.exe, or SCIATRAN_CRAY.exe),

The executable file reads the main user interface files control.inp and control2.inp which must be located in the current directory. The location of the other input files (additional *.inp user interface files, files containing atmospheric profiles, trace gas absorption cross-sections etc.) has to be specified in control.inp. All output files will be created in the directory VERSION1.2/Execute/.

The following output files can be generated:

intensity.dat

Sun-normalised radiance (``intensity'')

radiance.dat

Radiance in physical units

weightfn.dat

Weighting functions of trace gases, pressure, temperature, Rayleigh-scattering, aerosol scattering and absorption, and albedo

tg_amf.dat

Trace gas airmass factors

tg_vod.dat

Trace gas vertical optical depth (optical thickness)

vod2.dat

Vertical optical depth of Rayleigh-scattering, aerosol scattering and absorption, cloud scattering and absorption, and total extinction

flux.dat

Flux vertical profiles (actinic flux, up- and downwelling direct and diffuse flux)

SCIATRAN_SCENARIO.OUT

Several input settings
(Note that all input setting are send to standard output (screen) if the corresponding log-file flag has been set)

AEROSOL.OUT

Summary of aerosol input settings

errors.log

Contains WARNING and ERROR messages generated during program execution
