Abstract:
The aim of the present study is to analyze the correlations between ambient PM10 levels and meteorological parameters (temperature, relative humidity, atmospheric pressure, precipitations) in a small touristic location in Prahova Valley in two atmospheric regimes: a precipitating one with various rain rates and fair weather. The PM10 mass concentrations were determined using a medium-volume sampler with a time-sampling resolution of 12 hours for 10 successive days, covering different types of rainfall categories and fair weather. Meteorological parameters were measured using an automatic weather station that operated at 1 min resolution, which were complemented with radar products (images, reflectivity, echo tops) from the C-band meteorological radar from National Meteorological Administration in Bucharest. We present and discuss the atmospheric aerosol mass concentrations during both main atmospheric regimes and correlations between them and meteorological parameters. Relationships between reflectivity and rainfall rates were also used. Results are useful for both air quality and modeling of aerosol-wet deposition studies.
