Abstract

Abstract: The influence of the temperature and relative humidity upon aerosol mass concentrations distributions has been discussed. The temperature affects the particles’ Brown movement and air convection, and the vertical changes of mass concentration meets the negative exponent law. The relative humidity affects water-soluble particle’s absorbtion of moisture, and is linear with the aerosol mass concentration. A model for retrieving aerosol mass concentration with temperature and humidity correction is developed and confirmed by experimental data. The result indicates that the model reflects the influence of the temperature and relative humidity to aerosol mass concentrations distributions.

Key words: temperature, relative humidity, aerosol, mass concentration, vertical distributions
