About our consortium

Clear Air

Clear Air is a consortium established in 2022 by The Royal Netherlands Meteorological Institute (KNMI), The Netherlands Organisation for Applied Scientific Research (TNO), SRON Netherlands Institute for Space Research (SRON) and the Delft University of Technology (TUD).


Clear Air establishes partnerships with other Dutch research and technology organization who make a contribution to our mission and support a national agenda. Furthermore, Clear Air will establish partners with foreign research organization to jointly achieve world class research. We work closely together with government agencies to support policy on and companies to support the spin-out of research.


The management team of Clear Air consists of Anton Leemhuis (TNO), Frank Helmich (KNMI), Aaldert van Amerongen (SRON), and Jérôme Loicq (TUD). The rotating chairmanship of the management is currently held by Anton Leemhuis. The Supervisory Committee of Clear Air consists of Prof. Dr. Gerard van der Steenhoven (KNMI), Prof. Dr. Michael W. Wise (SRON), Prof. Dr. Henri Werij (TUD) and A.P. de Jong (TNO).

Logo Sron


SRON Netherlands Institute for Space Research (SRON), the Dutch national expertise institute for scientific space research, part of the Dutch Research Council NWO. The institute combines science, technology and engineering. Its scientific expertise is in atmospheric satellite remote sensing, in particular radiative transport and trace gas and aerosol retrieval algorithms and CO, methane, CO2 emission quantification. SRON develops enabling technology and space-qualified instrumentation spanning the range from X-ray to far-infrared wavelengths;


The Royal Netherlands Meteorological Institute (KNMI), an agency of the Ministry of Infrastructure and Water Management and the national research and information centre for weather and climate. KNMI is Principal Investigator of both OMI that flies on NASA’s Aura satellite (launched 2004), and TROPOMI: the satellite instrument on board of the Copernicus Sentinel-5 Precursor satellite (launched 2017) and expert in retrieval algorithm development for trace gases and aerosols and interpretation of satellite data for air quality and climate research
Logo TNO


The Netherlands Organisation for Applied Scientific Research (TNO), a TO2 institute and 30+ year developer and supplier of optical satellite instruments and systems (hardware) for aerospace among which instruments that measure the composition of the atmosphere from space. The institute also has strong expertise in satellite data utilisation (assimilation), for example for analyzing and monitoring emissions and air quality.
