Description

The unique characteristics of the combined data set from MOZAIC and IAGOS (http://www.iagos.org) with its global-scale sampling on air traffic routes make it ideally suited for long-term characterizations in the extratropical UT, namely at mid-latitudes with the highest flight densities.

We will present trend analyses from 1996 to 2019 for absolute humidity, temperature, and relative humidity with respect to ice (RH_ice). Our focus lies on different altitude levels in the UT over the regions Eastern North America, North Atlantic and Europe. We believe that these trends are very well suited for comparison with trends calculated from the CDR-4 data product.
