Data assimilation

Data assimilation makes it possible to compare spatially and temporally separated observations. In this study global distributions of ozone, water vapour and methane have been generated from MIPAS near real time level 2 profiles. These are then validated against a range of independent observations.

The mass flux across the tropopause

The stratosphere and troposphere are two air masses with a range of contrasting properties. Theoretical work has shown that there is a net transfer of mass from the troposphere into the stratosphere at high latitudes. Ongoing work will seek to quantify this mass transfer by applying the theory analyses of atmospheric data.
