| Zusammenfassung |
| We compare the currently most precise, ground-based total O3
measurement techniques: Brewer and FTIR. We give an overview of the
similarities and the differences between the measurements and the retrieval
approaches of both experiments. We compare coincident measurements performed
at the Atmospheric Observatory of Izaña from 2005 to 2007 and demonstrate
that, if the properties of the instruments are well characterised, the
scatter between both experiments is as small as 0.5%. This is in agreement
with the theoretical predictions and confirms empirically that both
techniques are able to monitor total O3 amounts with a precision of
better than 0.4%. However, we found systematic differences between both
techniques of around 4.5%, which we think are mainly due to discrepancies
between the applied UV and infrared spectroscopic parameters. |
