About me

My main interest is in the study of air quality and climate change and their interrelationships by integrating in-situ and ground based measurements with space borne earth observation, primarily at the Cabauw Experimental Site for Atmospheric Research (CESAR) in the Netherlands. I am motivated to link stations like CESAR into coherent networks for atmospheric monitoring and satellite validation. I have ample experience in development of, exploitation of and research with various optical sensing techniques for minor atmospheric constituents, with main focus on LIDAR (Light Detection and Ranging). Applications of my work include profiling of tropospheric ozone, clouds, aerosols, water vapour and temperature. More recently, I am involved in the development team for retrieval of atmospheric composition from TROPOMI, that uses passive remote sensing techniques.
