文摘

We performed laboratory verification and field study with Novosibirsk Aerosol Diffusion Spectrometer (ADS). For the concentration range of 103–105 cm−3, there was a ±15% uncertainty in the number concentration by the ADS. The particle sizing of the ADS was 10% of the specifications of the polystyrene latex spheres. The ADS performed well during the field campaign in the aerosol size range from 3 to 200 nm. The ADS derived parameters for new particle formation showed a good agreement with other instruments.
