Abstract

Laser particle spectrometry is one of the leading measurement technologies engaged in environmental monitoring, measuring the aerosol contamination of the air inside and outside of urban regions. It has a number of benefits against other methods - e.g. the possibility of real time, in situ measurement with high time resolution. These features make the light scattering based measurement methods superior to others in a mobile environmental laboratory. Our previously developed instruments are based on laser light scattering collected from different angular regions (90°, forward and backward directions) and a special illumination system increase the sensitivity and the resolution of the sizing. A collection of the developed optical instruments and other devices based on different methods were installed into a mobile environmental laboratory for monitoring atmospheric aerosols, which allows the comparison of the results obtained from different measurement methods. This laboratory has been used in 3 measurement campaigns where measurements were performed in 6 different locations.
