Brief CV

Born 1956. Senior scientist, MSc, employed at DMI since 1990. Has long experience in research and development on precipitation related issues. Participated in the Environmental Ministry’s Marin Research Program 90 in which radar data were used to monitor precipitation in Kattegat sea area. Participated in various radar researching and review projects, e.g. review of radar correction and adjustment methods in UK, ESPRIT Programme 23475 for development of a high performance rainfall radar image processing for sewage systems control, survey on precipitation events in Denmark 1993-2004 for investigation of the potential of using radar data for now-casting of heavy rain, and estimation of radar precipitation for agro-meteorological purposes. Participated in the development of a model for correction of solid precipitation measurements. Has been project manager in an international activity on quality control of rain gauge observations by using weather radar data.
