Different methods of determining formation rates of 3 nm particles are\ncompared, basing on analysis of simulated data, but the results are\nvalid for analyses of experimental particle size distribution data as\nwell, at least within the accuracy of the applied model. The study shows\nthat the method of determining formation rates indirectly from measured\nnumber concentration data of 3-6 nm particles is generally in good\nagreement with the theoretical calculation with a systematic error of\n0-20%. While this accuracy is often enough, a simple modification to\nthe approximative equation for the formation rate is recommended. A\nbrief study on real atmospheric data implied that in some cases the\naccuracy gain may be significant.
