| Abstract |
CHAVG is a postprocessor program for computing running averages (averages that begin each hour and overlap) and end-to-end averages (averages that do not overlap) from hourly concentration files. Since running averages are greater than or equal to the end-to-end averages, there frequently may be a need to analyze concentration data (from measurement or from air quality simulation models, such as, the UNAMAP series) using both methods of averaging. Calculations are made for selected receptors, and these values are ranked for each of four averaging periods plus a fifth period selected by the user. Output tables are generated for each averaging period for each type of average selected by the user. This document describes the input, processing, and output of the program. |
