| Zusammenfassung |
| Water vapor, relative humidity and temperature in the upper troposphere and lower
stratosphere (UT/LS) derived from the ECMWF model is evaluated and compared to
long-term in-situ CARIBIC passenger aircraft measurements. The combination of a
sidewards-facing inlet for (gas-phase) water vapor and a forward-facing inlet for total water
(water vapor plus cloud water/ice) allows to distinguish measurements taken inside and
outside of clouds. Probability density functions are used to study the models capability
to forecast UT/LS humidity. Furthermore, seasonally and latitudinally resolved
vertical profiles have been inferred from ECMWF and CARIBIC data to investigate
the ability of the model to represent troposphere-to-stratosphere water transport. |
