A data reduction method is presented for instrumental measurement of aerosol particle size distribution by an Andersen sampler with wall loss or bounce-off, and an electrical aerosol size analyzer. The method is based on Twomey's non-linear iteration algorithm, and estimation of aerosol particle size distribution is made without assuming its form. Overfitting for size distribution data involving random noise is elimininated by using an χ2-test for convergence criterion of iteration.
It is concluded that this method is more effective for the estimation of aerosol particle size distribution than the conventional method, if the response function of the instrument is known.
