MODTRAN4 INSTALLATION AND I/O FILES This file outlines the steps required to obtain, install and execute MODTRAN4 on a UNIX system. It also describes the input/output (I/O) file structure for MODTRAN. This file should be read even if one has already installed the code, or is familiar with the installation process. This file is duplicated as the 'README' file in the MODTRAN distribution tar file. The top-level directory for MODTRAN4 is Mod4v1r1/, i.e. MODTRAN4 version 1, revision 1. For installation questions, contact: gail.anderson@hanscom.af.mil, ganderson@cmdl.noaa.gov, or jim.chetwynd@hanscom.af.mil With technical questions, contact: gail.anderson@hanscom.af.mil, ganderson@cmdl.noaa.gov, or lex@spectral.com NEW FEATURES MODTRAN4 adds the following features (references are in the user manual): Two Correlated-k (CK) options: the standard option which uses 17 k values (absorption coefficients) per spectral bin and a slower, 33 k value option primarily for upper-altitude (>40 km) cooling rate and weighting function calculations (CARD 1); An option to include azimuth dependencies in the calculation of DISORT solar scattering contributions (CARD 1A); Upgraded ground surface modeling including parameterized forms for spectral BRDFs (Bidirectional Reflectance Distribution Functions) and an option to define a ground target surface (H2) different from its surrounding surface. A high-speed option, most appropriate in short-wave and UV spectral regions, that uses 15 cm-1 band model parameters (CARD 1A); Scaling options for water vapor and ozone column amounts (CARD 1A); Improved, higher spectral resolution, cloud parameter database; and More accurate Rayleigh scattering and indices of refraction. Both Correlated-k options permit more accurate calculation of molecular absorption in the presence of multiple scattering. Without the azimuth dependent DISORT option, the multiple (not single) scatter solar contributions included in MODTRAN line-of-sight calculations are averaged over azimuth. The BRDFs are fully coupled into the Isaacs multiple scattering model; upon release of the recently developed BRDF-dependent DISORT, MODTRAN4 BRDF's will be coupled to that code. The dual surface option enables modeling of adjacency effects. The updated Rayleigh scattering algorithm models the spectral dependence of the depolarization factor, and the refractivity (equal to one minus the real part of the index of refraction) now varies not only with water density but also with CO2 partial pressure (Bodhaine, et al., 1999). All MODTRAN3.5 and MODTRAN3.7 input files are fully compatible with MODTRAN4. Minimally, six input cards (1, 1A, 2, 3, 4, and 5) are required to run MODTRAN for a given problem. For specific problems, combinations of several additional optional control cards are possible. INSTALLATION STEPS 1) Contact Gail Anderson (email: gail.anderson@HANSCOM.AF.MIL) or Jim Chetwynd (jim.chetwynd@hanscom.af.mil) and obtain the code (bundled into a single UNIX tar file and compressed to save space). 2) Untar the file: 'tar xvf Mod4v1r1.tar'; this will build the MODTRAN4 directory structure. The top-level directory, Mod4v1r1/, will contain these sub-directories: DATA/, docs/, mie/, mod4_obj/, mod4_src/, novam/, novam/src/, novam/test/, PC/, PC/DATA/, PC/mod4_obj/, PC/mod4_src/, PC/TEST/ PC/TEST/SAVE/, TEST/ and TEST/SAVE, 3) Create Correlated-k binary data files in the DATA/ subdirectory. In that directory, compile CKBIN.f (f77 CKBIN.f -o CKBIN.exe). Run CKBIN.exe; you will be prompted for a Correlated-k ASCII file name. Reply 'CORK15.ASC'. This file should have been placed in the DATA/ directory during the untar process. You will then be prompted for a binary name; reply with 'CORK15.BIN'. The program should announce a successful write and place the file in the DATA/ directory. Repeat for 'CORK01.ASC'. 4) Create band model parameter files. Compile and run MOLBMP.f. Select an ASCII-to-binary conversion. Although entering names of ASCII files is possible, the current files of interest should appear in the menu: BMP99_15.ASC and BMP99_01.ASC. Another menu permits choosing output file names; select the corresponding .BIN names. The outputs of the conversions specify the value, for your computer, of the RECL parameter. Note this number for the following step. 5) In the mod4_src/ subdirectory, edit the file openbm.f. Find the 'RECL=' specification in the OPEN statement, and change its value to that specified by MOLBMP.exe for your platform and compiler. For an HP 9000/735, for example, the value will be 60; for an SGI, 15; for GNU and PC (Lahey and WATCOM) compilers, it is also 60. 6) The command 'make -f Makefile' will run the FORTRAN compiler (using 'Makefile') to create the executable file Mod4v1r1.exe. Object files will be placed in the mod4_obj/ directory. You may need to edit the makefile to set compiler parameters as needed by your compiler. Most likely, editing will not be needed. 7) This version of MODTRAN (version 3.7 and higher) has the ability to use the Navy Oceanic Vertical Aerosol Computer Model (NOVAM). If you need to use this code, NOVAM must be compiled and run before MODTRAN, producing output files for use when needed. The NOVAM files are located in the novam/ subdirectory tree under the top MODTRAN directory. Not all users will require NOVAM. MODTRAN is independent of NOVAM. To prepare using NOVAM, go to the novam/ subdirectory. Execute the UNIX script file createnovamexecutable, which will create the NOVAM executable, novam.exe. NOVAM (novam.exe) reads input from novam.in, and writes output to novam.out. Three test case inputs are located in the novam/test/ subdirectory. Copy one into the novam.in file name, or create one, and use 'novam.exe' to create novam.out. Copy that to NOVAM.OUT (upper case) in the topmost MODTRAN directory, which contains Mod4v1r1.exe, for use in runs requiring NOVAM data. 8) The TEST subdirectory holds a number of input files designed to exercise various parts of MODTRAN4. The input files are named in the pattern *.tp5; output files have .tp6, .tp7, .tp8, .7sc, .7sr, .plt, .psc, .clr, .chn, and .flx extensions. Copy a *.tp5 file into tape5 in the top-level directory, and then 'Mod4v1r1.exe' will run that case. The other way of running MODTRAN and naming I/O files make use of the file 'modroot.in' or 'MODROOT.IN' as described below. For MODTRAN4, the *.tp6 output files shipped were created on a UNIX platform. 9) The subdirectory 'PC/' contains an executable, and binary files, for a PC. You need not compile the DATA/ files for the PC. I/O FILES An attempt has been made in MODTRAN4 to make it easier for the users to keep track of input and output (I/O) files. The need for easier file handling is evident to anyone who runs MODTRAN using different tape5's and wants to save the corresponding output files (the tape6's, pltout's, tape7's and so on). The problem is that every MODTRAN input file must be called 'tape5' and that earlier I/O files must be renamed to avoid overwriting them with newer files. The need for renaming is now avoided by creating a new MODTRAN input file (referred to as the root name file) called modroot.in or MODROOT.IN. If 'modroot.in' does not exist, 'MODROOT.IN' is looked for. If neither exists, MODTRAN I/O files are the usual ones: 'tape5', 'tape6', 'tape7', 'tape8', etc. If the root name file exists and contains a non-null string (maximum length is 80 characters), this string is treated as a prefix. It is suggested that this string contain no blanks other than leading and trailing ones. If the string consists of all blanks or is a null string, the I/O files are the usual ones. Otherwise, this string, stripped of all leading and trailing blacks, is used as a prefix for the I/O files whose names have mnemonic suffixes listed below. As an example, if the string is 'case1', the MODTRAN I/O files will have these names: case01.tp5 (corresponding to tape5) case01.tp6 (corresponding to tape6) case01.tp7 (corresponding to tape7) case01.tp8 (corresponding to tape8) case01.7sc (corresponding to tape7.scn case01.7sr (corresponding to tape7.scr) case01.plt (corresponding to pltout) case01.psc (corresponding to pltout.scn) case01.clr (corresponding to clrates in MODTRAN4) case01.chn (corresponding to channels.out in MODTRAN4) case01.flx (corresponding to specflux.out in MODTRAN4)
