Assessment of the nocturnal boundary layer height based on long-term atmospheric radon measurements

Joanna Aleksandra Kubiak et al.

Summary: The article presents the results of statistical analysis of meteorological and atmospheric radon concentration measurements carried out in Krakow from 2004 to 2013. The study estimated the height of the nocturnal boundary layer based on diurnal variability and compared it with ERA5 data. The average radon concentration in the air in Krakow during that period was (5.262 +/- 0.017) Bqm(-3). The study identified diurnal and seasonal variability of radon concentration and analyzed the correlation of meteorological parameters. The results showed statistically significant correlations for wind speed (r= -0.38, p < 0.001) and air humidity (r=0.33, p < 0.001). The study confirmed the possibility of determining the nocturnal boundary layer height based on radon measurements, but further refinement of the calculation model is needed.

The Way of Usage and Location in a Big City Agglomeration as Impact Factors of the Nurseries Indoor Air Quality

Malgorzata Basinska et al.

Summary: The study found that the indoor air quality in three out of four nurseries in Poznan was poor and needed improvement by supplying outside air. Ventilating rooms when the outside air is polluted can reduce CO2 concentration but worsen indoor particulate matter levels.
