Lay summary

The DIAMO project is the extension of the SNF project „Climatology of gravity wave-induced ozone perturbations“. The aim of the DIAMO project is the understanding of wave-mean flow interactions and their relationship to atmospheric composition changes on time scales from minutes to decades. The project is divided into three work packages WP1, WP2, and WP3. Each package is closely linked to the activities of the other packages.

WP1: Long-term monitoring of stratospheric ozone and dynamics

The IAP/Uni Bern has a long-term data set of stratospheric ozone above Bern from 1994 to 2010 with a time resolution of 3 min. Numerical simulations of WP2 permit us to link the perturbations of atmospheric composition and atmospheric dynamics. We investigate:

-Interannual and seasonal modulation of atmospheric waves above Bern; -Climatology of fluctuations and intraseasonal oscillations of stratospheric ozone; -Trend study of stratospheric ozone, temperature, and dynamics above Bern.

WP2: Simulation of gravity waves and wave-induced changes of atmospheric composition and mean flow Numerical simulations are performed with the Weather Research and Forecasting Model (WRF):

-Interaction of atmospheric gravity waves and the mean flow; -Interplay between gravity waves, cloud formation and precipitation; -Impact of gravity waves on stratospheric ozone; -Intercomparisons of simulations and observations (e.g., IAP database).

WP3: Spaced antenna measurements for 3D monitoring of atmospheric motions

The DIAMO project utilizes spaced antenna and multibeam data of ground-based microwave radiometers for time lag measurement of coherent signatures of ozone perturbations:

- 3D monitoring of the propagation of atmospheric gravity waves through the stratosphere and lower mesosphere;

-Determination of middle atmospheric winds by means of the drift velocity of ozone irregularities.
