CARLOTTA - Climatology of ascending Airstreams and their Relation to the Long-range Transport of Trace substances in the...
During CARLOTTA we established the first long-term climatology of so called warm conveyor belts (WCBs) and the first long-term climatology of global-scale pollutant transport. The analysis of the pollutant transport climatology is based on calculations with the Lagrangian particles dispersion model FLEXPART, over a 15-year period. The typical pathw...

An upgraded estimate of the radiative forcing of cryoplane contrails
The radiative forcing of contrails is quantified for a hypothetical fleet of cryoplanes in comparison with a conventional aircraft fleet. The differences in bulk optical properties between conventional and cryoplane contrails are determined by numerical simulations, under several ambient conditions, of the microphysical evolution of conventional an...
Development of runoff in subcatchments of the River Rhine Simulations of the current state and for climate change scenar...
This report ''development of runoff in subcatchments of the River Rhine -simulations of the current state and for climate change scenarios'' investigates the impacts of possible future climate changes on runoff and runoff regime in selected subcatchments of the River Rhine. The regional climate in the selected subcatchments Mosel (up to gauge Coche...
Predictor-optimized downscaling combined with weather generators: seasonal and daily climate change scenarios for topogr...
Empirical downscaling is based on statistically derived relationships between observations on different scales. It has its roots in synoptic climatology, which relies on the relationships of local scale weather to large scale atmospheric processes. Mid latitudes' weather depends on the seasons, hence, empirical downscaling has to be conducted for e...

Improvement of the ozone forecast / Verbesserung der Ozonprognose
Although ozone is not in public focus as 5 to 10 years ago, high ozone concentrations, especially under the impression of the summer 2003, are still a problem. The EU legacy and the German national legislation are trying to cope with the problem. This work presents a new method for ozone forecasting. It is based on statistic procedures. Two dataset...
Climate impact of contrails: investigations by means of an atmospheric general circulation model / Klimawirkung von Kond...
A parameterization of line-shaped contrails for use within the framework of a general circulation model (ECHAM) was developed for the first time. Contrail coverage, optical properties and radiative forcing are calculated at any model time step depending in a physically based manner on the respective conditions in the ambient air. In addition, possi...
