ModelPgm.pdf contains draft documentation of the use of the SAPRC modeling software for basic model simulations. This gives details of the programs, their inputs and outputs, file formats, and examples of their use. The curent version is a major update of the previous version that was dated 2017, and now includes a more complete discussion of the lumping program and now discusses the programs and files for calculation of reactivity scales. However, this document is still a draft that is not completely proofread and is subject to change. Please contact me if you see errors, undocumented behavior, or unclear or erroneous text. The current version is dated October 7, 2020.Programs and files. See ModelPgm.pdf for more details. These files were updated on May 15, 2023 unless indicated otherwise.
SAPRCsys.pdf is a presentation made to the CARB staff in November, 2017, that gives an overview of the SAPRC mechanism development systems and programs as of that date. Although not comprehensive and includes discussion not directly relevant to this software, and may be an easier place to start than ModelPgm.pdf, which gives more complete documentation. This was uploaded on April 15, 2020.
MECH.ZIP contains the files implementing the various versions of the SAPRC mechanismss listed above. It now contains the current version of SAPRC-22, wich was updated on September 9, 2023. Created on September 9, 2023.
PGMS.ZIP contains the SAPRC modeling programs needed to run the environmental chamber simulations and the test calculations. These programs can be compiled using the public domain gfortran compiler. Templates for Excel spreadsheets with macros that can be used to summarize and plot data from the experiments and calculations are also included.TESTCALC.ZIP contains the files needed to run various test calculations using the mechanisms, including the static and multi-day dynamic test calculations used in the development of CSAPRC-07, the condensed version of SAPRC-07.
CHAMCALC.ZIP contains the files necessary to use the distributed mechanisms and software to evaluate the mechanisms against the chamber data. Because of the large number of chamber experiments now available, this archive only contains a input and experimental results data for only a small subset of representative experiments for testing the programs. Files for the complete set of experiments are contained in a separate archive discussed below.
CHAMEXPT.ZIP contains the input files and expeerimental results files for the chamber experiments used when evaluating various versions of the SAPRC mechanisms (except for CSAPRC-07, which is derived directly from SAPRC-07). The archive now contains a total of 2915 chamber experiments, including new experiments from the UCR and CSIRO chambers used for the SAPRC-11 mechanism evaluations, but excluding UNC chamber experiments.(UNC chamber experiments have been removed from our distribution if files because our UNC input files may not represent the best inputs for these experments.) The experiments are listed and summarized in the file CHAMEXPT.XLS, which is included in both CHAMCALC.ZIP and CHAMEXPT.ZIP. This archive was last updated June 27, 2017.
REACT.ZIP contains the files necessary to do reactivity scale calculations using the SAPRC-07 mechanism, including the MIR, MOIR, EBIR, base case, and averaged conditions scales. This is the latest version of SAPRC for which complete reactivity scales are available. Reactivity calculation files for updated versions are not yet available.
MINGF.ZIP contains the minimum set of dynamic link library (.DLL) files needed so that the compiled programs in the distribution will run without GNU MinGW gfortran being installed. Note that these are not sufficient to compile new or modified mechanisms or change any of the programs, and they should be deleted if other compilers or new versions of gfortran are used. It is recommended that the user install GNU MinGW gfortran as described in ModelPgm.pdf rather than using these files. These files are dated 12/1/2011 and should not be used with programs compiled with different versions. DO NOT INSTALL THESE FILES IF YOU HAVE, OR PLAN TO HAVE, MINGW AND GFORTRAN INSTALLED!
