Parameters (PARAMS) Program User's Guide, Version 1.0, for indoor emission source modeling
Although over 50 indoor emission source models have been developed (Guo, 2002a), few are widely used in indoor exposure assessment. This imbalance is partially caused by the fact that many source models contain one or more parameters that are difficult to determine. This program is a step toward alleviating this problem by providing 30 methods for estimating some of the parameters in those source models. It is useful to those who develop or use indoor air quality (IAQ) and exposure models, and those who develop or use quantitative structure activity relationship (QSAR) models. In addition, many methods in this program are useful to researchers in areas other than indoor air quality. Users can benefit from this program in two ways: (1) it serves as a handy tool by putting commonly used methods in one place, and (2) it saves users’ time by taking over tedious calculations.
This user's guide provides information on the PARAMS program, which was developed based on the developer’s review of existing parameter estimation methods for indoor emission source models (Guo, 2002b). Users are encouraged to consult with the original references, which are listed in the guide.
