Abstract

Atmospheric ion mobility spectra were measured at Maitri, Antarctica, using an indigenously fabricated ion mobility spectrometer in January-February 2005 during the 24th Indian Antarctic Expedition. The ion mobility spectrometer was fabricated and tested at the Indian Institute of Tropical Meteorology, Pune, India. As the ion mobility depends on the diameter of the particles, the aerosol size distribution was derived from the observed ion mobility spectra using the KL model. The model was tested by comparing the derived spectra with the observed spectra using the Scanning Mobility Particle Sizer and the Aerodynamic Particle Sizer. We show that the KL model can reasonably reproduce the observed size distribution except in the accumulation mode. Relevant meteorological parameters are also reported, which aid in the interpretation of the results.
