Clear air is a consortium of R&D organizations who make a contribution to the field of atmospheric monitoring.

We have a strong focus on the design and development of innovative satellite instruments, retrieval algorithms and the modeling of atmospheric chemistry and emissions.

More about our research

Mission and Vision

The Clear Air consortium comprises of R&D organizations who are involved research and technology development for monitoring of the atmosphere. We aim at being globally outstanding for the use of satellite instrumentation and data products for the understanding and mitigation of climate change, air pollution and preservation of biodiversity.

The mission of Clear Air is to

To align Dutch national expertise and R&D efforts in this field;
To stimulate collaboration within the (inter)national Earth Observation community and across research domains;
To develop applications that can be used in and beyond the air quality and climate domain that will benefit science and society;
To broaden the use and thus impact of our knowledge and satellite data by policy makers and scientists alike;
To cooperate with the growing commercial space sector and data service providers market to allow spin-offs;
To develop a national Earth observation strategy and intensify the national space programme for Earth observation, including the development of new instruments.

PACE climate satellite releases first images

News 12 April 2024

NASA’s PACE climate satellite with the Dutch instrument SPEXone onboard now offers the world access to satellite images distinguishing types and sizes of aerosols. SPEXone also measures the extent to which aerosols absorb and reflect sunlight.

ESA selects Dutch satellite system for local emission monitoring

News 21 February 2024

The new Dutch TANGO satellites will soon be able to detect sources of greenhouse gases. For example, power plants, coal plants, landfills and factories. As a result, scientists will soon be able to detect 75% of the methane emitted by humans worldwide. That figure was 5% so far using TROPOMI. ESA has approved the TANGO mission.

The Netherlands can make a major impact: measuring methane down to the local scale

Blog 1 October 2023

The Netherlands is now able to make a big impact on the inventory of the greenhouse gas methane released into the atmosphere by humans. And consequently, in the understanding of where we can most rapidly address this worldwide.

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;

KNMI

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

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.

TU Delft

Delft University of Technology (TU Delft), performing research, and engineering of end-to-end space systems. The university is ranked number 1 in Europe and top-5 worldwide on the subject of Aerospace Engineering. The university has also relevant expertise on atmospheric chemistry, data retrieval, supercomputing, and optical instrumentation. Its Climate and Delft Space Institute bring together the expertise of scientists across the university in the field of data-based climate knowledge for mitigation, adaptation, space instrumentation and policy.
