| Zusammenfassung |
| Different methods of determining formation rates of 3 nm particles are
compared, basing on analysis of simulated data, but the results are valid for
analyses of experimental particle size distribution data as well, at least
within the accuracy of the applied model. The study shows that the method of
determining formation rates indirectly from measured number concentration
data of 3–6 nm particles is generally in good agreement with the
theoretical calculation with a systematic error of 0–20%. While this
accuracy is often enough, a simple modification to the approximative equation
for the formation rate is recommended. A brief study on real atmospheric data
implied that in some cases the accuracy gain may be significant. |
