Cave microclimatology: diurnal variations in aerosol particle concentrations

Popis výsledku v původním jazyce

Based on a case study in speleotherapeutic Cisaska Cave (Moravian Karst, Czech Republic), the behavior of cave aerosol was studied. The particle size distribution in the aerosol showed an atypical shape with majority of nucleation mode particles. The particle number concentrations oscillated diurnally with the amplitude of 1935cm(-3) (nanoparticles in the range of 6-154nm) and 436cm(-3) (submicron particles in the range of 154-942nm). This behavior was simulated under the use of simplified dynamic model. At the model optimization, it was found that the part of aerosol particles (submicron particles especially) was introduced into the cave from exterior by cave ventilation (controlled by external temperature) with participation of external wind and traffic. Other parts of the particles (the nanoparticles especially) probably arose directly in the cave. The presented findings could be important for better understanding of the factors governing cave microclimate.
