Analysis of tools aimed at managing ambient air quality in Perm city

The article dwells on analyzing tools aimed at managing ambient air quality on the example of Perm city and basing on the experience in using systems for dynamic standardizing. The authors discuss advantages and drawbacks of managing ambient air quality with unified programs for calculating atmospheric contamination (Russian abbreviation UPRZA), We analyzed drawbacks in methodology that could result in overstating when emissions from stationary sources were inventoried; those drawbacks didn't allow using results of dispersion calculation for managing ambient air quality. Basing on data taken from literature sources and experience in UPRZA systems application, we suggest to cease applying UPRZA for operative ambient air quality management; instead, we propose to calculate admixtures dispersion with software that has been tested and used worldwide and that is freely accessible. Such software enables modeling actual meteorological conditions using data on wind profile and air temperature at various heights...
