| Subject | |
| The project develops a model system for atmospheric pollutant dispersion simulation at various resolutions (order of 1km, order of some meters). This system can be used to assess and control air quality in accordance with European guidelines. The model system (M-SYS) will be based on the existing obstacle resolving micro-scale transport and fluid model MITRAS with chemistry model MICTM and the existing mesoscale transport and fluid model METRAS with chemistry model MECTM. These models will be harmonised, nested and extended. The model system M-SYS will be able to simulate wind and temperature fields as well as concentration and deposition of gas phase and aerosol based pollutants in the mesoscale and in the obstacle resolving micro-scale. The project objectives are the following:

| Subject | |
| In this subproject of the EU project ANICE (Atmospheric Nitrogen Inputs into the Coastal Ecosystem) the mesoscale model METRAS will be applied to simulate coastal atmospheric phenomena including the nitrogen transport and the composition of coastal aerosol. The aerosol model SEMA which is currently restricted in its application range to wet aerosols will be extended to dry aerosols and imlemented in the fortran 90 version of the mesoscale model METRAS. Scenario studies will be performed to calculate the atmospheric nitrogen input to coastal waters in a high resolution in space (some 100 meters) and time (some minutes). The model results will be compared with measurements. To detect important atmospheric processes, the characteristic time scales of the different processes are calculated. | |

| Subject | |
| The aim of this project is to investigate how the development of cyclones in the North Atlantic region is influenced by the orography, the sea surface temperature, and the large-scale circulation. Furthermore, the effect of the cyclones on the ice drift and the effect of the ice drift on the development of the cyclone are considered. The region of the Greenland sea (Framstrait) is primarily studied. The overall goal of the project is to derive the relevance of large-scale and mesoscale influences for the development of a cyclone. For the investigations two mesoscale atmospheric models of different resolutions (REMO and METRAS ) are used. The models are nested inside one another: REMO (1/6° resolution) is nested in REMO (1/2° resolution) and METRAS (8 km resolution) ist nested in REMO (1/6° resolution). METRAS is coupled to a dynamic sea ice model. Besides sensitivity studies with well controlled boundary and initial values real data simulations are performed to hit the project objectives. From model results the fluxes of heat and momentum in the area of subsynoptic lows are determined and the quality of the model results is checked by comparing them with measurements and the REMO results with results of the higher resolving model METRAS. | |

| SYKON (Synthesis and New Concept for North Sea research) was an interdisciplinary project to summarize the existing knowledge on the ecology and processes in the area of the North Sea. In this subproject of SYKON the status of emission data, measurement instrumentation and meteorological and air quality data has been identified and assessed for the North Sea region. Atmospheric models which are able to simulate the fluxes towards the sea surface in time scales of weeks, months and decades have been compared. Open questions connected to future studies of the North Sea and to development of an ecosystem model have been pointed out. | |

| The principle aim of the project was the determination of the sensitivity of the high-resolution chemistry transport model METRAS with respect to different nesting strategies and emission datasets. In addition, different parameterizations of physical and chemical processes (turbulence parameterizations, chemical reaction schemes) have been investigated. Using ozone (area averaged means, extreme values, time series) as target variable, the sensitivity of model results will be determined based on the different representation of the above mentioned process parameterizations and boundary values. The numerical study is related to the intensive field measuring campaign TRACT, which took place in the Upper Rhine Valley in September 1992. In order to yield more general results, the relations between the variation of model results and the applied formulations of physical and chemical processes will be inspected. | |

| This project contributes to the development of a microscale, obstacle resolving transport and fluid model ( MITRAS ). This model can be used to calculate flow, temperature and humidity fields as well as chemical transformations of pollutants. The model MITRAS will be applied to idealized as well as close-to-reality obstacle configurations. The model development is a cooperation of five projects (namely TFS-LT1:B1 to B5). The model development is coordinated by the present project (B1). For this purpose standards have been set for the model development, for model testing and for the model documentation. The modules of the model, which are developed in the projects B3 to B5, are quality checked, integrated in the model and tested within the model surrounding in project B1. In cooperation with project B2 (MITRAS-Data) and with TFS-projects of LT1-C, a validation concept for microscale models is developed. Special focus will lie on the comparability of model results and results of wind tunnel experiments. The validation concept, which will be applicable to obstacle resolving models, will be applied to MITRAS. Results of the validation and the validation concept will be documented. | |

| The main objective of the project is the development of a validation concept to evaluate high resolution chemical transport models (hrCTM). The concept is developed in close cooperation with the other project groups of TFS1 working group C. The new validation concept will be based on the existing validation concept for passive tracers which will be extended to chemically reactive pollutants. To derive a measure for the reliability of model outputs main emphasis is given to the determination of both the sensitivity and the variation of the model results depending on uncertainties of initial input values. The evaluation is based on characteristic parameters which are important during photosmog episodes in summer. As an example, the validation concept is applied to the mesoscale transport model METRAS. | |

Based on the mesoscale model METRAS a PC version ( METRAS PC ) is developed. METRAS PC calculates wind, temperature and humidity with fixed boundary values or by calculating and including the diurnal changes of surface temperature and humidity. The model output may be used to drive air pollution transport models. To ensure the model quality comparisons of result of METRAS PC and METRAS are performed. A user manual gives hints how to drive the model and how to interpret the results. | |

| Subject | |
| In the project the mesoscale transport- and fluid model METRAS , which has been developed at the University of Hamburg, was extended to take into consideration the tide and instationary and inhomogeneous synoptic weather conditions. Working together with the mentioned cooperation partners the existing moduls concerning the chemical reactions and the deposition of nitrogen components have been further developed. To calculate spatially and temporally highly-resolved fluxes of momentum, heat, radiation and matter depending on meteorological and oceanographic conditions, model simulations have been performed for selected episodes and the KUSTOS experimental periods. These model simulations have been performed using the large-scale forcing data supplied from the routine weather forecast model (Deutschland Model) of the German Weather Service (DWD) as well as the tide and water surface temperature data calculated by the Deutsche-Bucht-Model (DBM) of the Institut für Meereskunde. The METRAS simulation results supply the atmospheric forcing for the Deutsche-Bucht-Model in a high resolution. In addition data of radiation and nitrogen input into the coastal sea have been derived. | |
