The Chemical Mass Balance (CMB) air quality model is one of several receptor models that have been applied to air resources management. EPA-CMB8.2 incorporates the upgrade features that CMB8 has over CMB7, but also corrects errors/problems identified with CMB8 and adds enhancements for a more robust and user-friendly system. EPA-CMB8.2 is a 32-bit (Windows (Trademark) 9x and higher) version of CMB modeling software that substantially facilitates the estimation of source contributions to speciated PM10 (particles with aerodynamic diameters nominally less than 10mm), PM2.5 (particles with aerodynamic diameters nominally less than 2.5mm), and Volatile Organic Compounds (VOC) data sets. EPA-CMB8.2 features: (1) full use of Windows (32-bit) for file access/management, (2) a tabbed page interface that eases the necessary progression for doing a CMB calculation, (3) multiple, indexed arrays for selecting fitting sources and species, (4) versatile display capability for ambient data and source profiles, (5) mouse-overs and on-line help screens, (6) increased attention to volatile organic compounds (VOC) applications, (7) correction of some flaws in the previous version (CMB7), (8) flexible options for input/output data formats, (9) addition of a more accurate least squares computational algorithm, (10) upgraded linear algebra library, (11) a new treatment of source collinearity, and (12) choice of criteria for determining best fit.
