My main interest is in the study of climate change and the interrelationships with air quality, primarily using ground based remote sening techniques at the Cabauw Experimental Site for Atmospheric Research (CESAR) in the Netherlands.

Integrating in-situ and ground based measurements with space borne earth observation, broadens the perspective to larger scales. I am motivated to link stations like CESAR into coherent networks for atmospheric monitoring.

I have ample experience in development of, exploitation of, and research with various optical sensing techniques for minor atmospheric constituents, with emphasis on LIDAR (Light Detection and Ranging). Applications of my work include profiling of tropospheric ozone, clouds, aerosols and water vapour.
