A measuring method using a reference CNC (Condensation Nucleus Counter) combined with the conventional DMA/CNC system has been developed to obtain the correct size distribution of atmospheric ultrafine aerosols. It is difficult to measure correct size distributions of atmospheric aerosols because of the fluctuation of size distribution and concentration in a sizing period. The method proposed here is capable of correcting the fluctuation of the particle concentration in each particle size range of DMA by the simultaneous measurement of total number concentration of aerosol with the use of the additional set of reference CNC. Some simulation studies assuming the variation patterns of size distribution have been performed. It was found that this technique was useful to measure size distributions which fluctuate with time like atmospheric aerosols.
