| Zusammenfassung |
| During a series of 8 measurement campaigns within the SPURT project
(2001-2003), vertical profiles of CO and O3 have been obtained at
subtropical, middle and high latitudes over western Europe, covering the
troposphere and lowermost stratosphere up to ~14 km altitude during
all seasons. The seasonal and latitudinal variation of the measured trace
gas profiles are compared to simulations with the chemical transport model
MATCH. In the troposphere reasonable agreement between observations and
model predictions is achieved for CO and O3, in particular at
subtropical and mid-latitudes, while the model overestimates
(underestimates) CO (O3 in the lowermost stratosphere particularly at
high latitudes, indicating too strong simulated bi-directional exchange
across the tropopause. By the use of tagged tracers in the model, long-range
transport of Asian air masses is identified as the dominant source of CO
pollution over Europe in the free troposphere. |
