Key qualifications 

Development of air quality models for local scale dispersion as well as mesoscale to long range transport. Coordinator for groups in the department:

the Air Pollution Modelling (1993-95), Human Exposure and Urban Air Pollution (1998-2002). Head of the department's section for Human Exposure and hazardous organic compounds (2003-). Local scale modelling including participation in the development of the well-known Operational Street Pollution Model (OSPM) for pollution emitted from traffic in urban streets (1987-90). This work evolved into modelling human exposure to air pollution mainly from traffic (1994-). Coordination of two large applications on human exposure to air pollution funded by the Danish National Environmental Research Programme: HEAP (funded with 5 mill dkr) in 1996, and CONTRAF (funded with 7,5 mill dkr) in 2000. Mesoscale modelling of air pollution including a strong role in the development of the Atmospheric Chemistry and Deposition (ACDEP) model; a variable scale Lagrangian transport-chemistry model for describing nitrogen deposition to coastal marine waters. A special version of this model has been applied for describing the atmospheric chemical degradation of biogenic sulphur compounds (DMS) emitted from the sea. Coordinating of a study on air-sea exchange processes (ASEPS) that included a field experiment at Vindeby, Lolland, Denmark (1993-96). Apply each year the ACDEP-model for calculations of nitrogen deposition to the Danish Marine waters in the Danish Background Monitoring Programme (1995-). Have applied the ACDEP-model for calculations within several EU funded research projects.

Profile

My key expertise is within assessment of human exposure to air pollution and assessment of atmospheric nutrient loadings on nature applying integrated monitoring assessment (combined use of measurements and model calculations); this was the topic of my higher doctoral degree. I am working with personal exposure monitoring (PEM) and I am deeply involved in testing and applying low-cost sensors and passive samplers for PEM. I am a modeler by training and have played a key role in the development of the Operational Street Pollution Model (OSPM); a model that is now applied in more than 20 countries around the world. I took part in the development of the Eulerian Backward Ierative (EBI) method for solving chemistry in chemistry-transport models (CTMs) used by the US-EPA as their standard method. In my PhD project I developed a Lagrangian chemistry-transport model for studying atmospheric degradation of biogenic Sulphur compounds in the atmosphere. Parts of this model were later used for developing a model for atmospheric deposition to nature (ACDEP – atmospheric chemistry and deposition model) that for 10 years was applied for mapping Nitrogen and Sulphur deposition to Danish nature.
