Satellite department at KNMI

Our GRS – TU Delft group benefits from great supports of the Research & Development Satellite Observations department, The Royal Netherlands Meteorological Institute (KNMI), De Bilt, the Netherlands


Here is a list (non exhaustive) of the main colleagues with whom I use to exchange and collaborate on a regular basis:


Prof.dr. P.F. (Pieternel) Levelt: Principal Investigator (PI) of OMI (Ozone Monitoring Instrument) on the NASA EOS Aura satellite, head of the Research & Development Satellite Observations department at KNMI, professor of remote sensing of the atmosphere at TU Delft.

Dr. J.P. (Pepijn) Veefkind: Principal Investigator (PI) of TROPOMI (Tropospheric Monitoring Instrument) on the Sentinel-5 Precursor satellite mission, deputy PI of OMI (Ozone Monitoring Instrument) on the NASA EOS Aura satellite, affiliated with KNMI and  the GRS department.

Dr. T. (Tim) Vlemmix: Formerly, assistant professor in remote sensing of atmospheric composition at TU Delft.. Now, researcher on new sensor design for NO2 observations (cf. Tropolight). His research focuses mostly on the remote sensing of tropospheric NO2, an important component of air pollution.

Dr. Folkert Boersma: Atmospheric scientist and teacher at Wageningen University (Meteorology and Air Quality Group) and the Royal Netherlands Meteorological Institute (KNMI). His research aims to better understand the sources, the concentrations, and the effects of air pollution by using satellite measurements. Scientific co-ordinator for the European Union FP7 research project Quality Assurance from Space (QA4ECV).

Stimulating exchanges, through my current research project, on tropospheric NO2 retrieval from OMI measurements, related uncertainties, and the nested effects of clouds / aerosols & their correction schemes. Strong and rigorous scientist.

Dr. Piet Stammes: Senior scientist at KNMI, dedicated to radiative transfer (RT) in the solar spectral range, and retrieval of clouds, aerosols and trace gases from satellite measurements of scattered solar radiation. Specific topics are RT modelling (DAK model), O2 A-band, polarisation, and simple retrieval techniques. He is involved in several projects using GOME-1, SCIAMACHY, OMI, GOSAT, and GOME-2 satellite data.

Expert advices on aerosol effects and radiative transfer modelling, for single and multiple light scattering, in the UV and visible spectral range. Great positive supports on my research analyses and the novel developed OMI aerosol height algorithms.
