Who We Are - WCCAP

World Calibration Centre for Aerosol Physics
Go to content

The World Calibration Centre for Aerosol Physics (WCCAP) was established in 2002. It is based on the WMO-GAW's mandate to countries to provide quality assurance and quality control in the field of aerosol in-situ measurements. The WCCAP is base-funded by the Federal Environmental Agency and hosted by the Leibniz Institute for Tropospheric Research in Leipzig, Germany.


Our aim at WCCAP is high level scientific research. Therefore, we enable and support researchers, institutes, manufacturers and third-parties to perform aerosol in-situ measurements with the highes quality possible. We reach this goal by providing a variety of calibration workshops, audits, hands-on trainings, etc. Furthermore, our expertise is incorporated in recommendations and SOPs which are open to the community.

We are part of several cooperations and projects such as, but not limited to, RI Urbans, Aeromet, ZIN Project.
Within the pan- European Research infrastructure ACTRIS, the WCCAP is currently the leading unit of the European Center for Aerosol Calibration and Characterization (CAIS-ECAC).


WMO - World Meteorological Organization

As a specialized agency of the United Nations, WMO is dedicated to international cooperation and coordination on the state and behaviour of the Earth’s atmosphere, its interaction with the land and oceans, the weather and climate it produces, and the resulting distribution of water resources.

Global Atmosphere Watch (GAW)

The Global Atmosphere Watch (GAW) Programme of WMO focuses on building a single coordinated global understanding of atmospheric composition, its change, and helps to improve the understanding of interactions between the atmosphere, the oceans and the biosphere. It coordinates high-quality atmospheric composition observations across global to local scales to drive high-quality and impact science while co-producing a new generation of research enabled products and services.


UBA- Umweltbundesamt

For people and the environment - is the motto of the Federal Environment Agency.  As Germany's central environmental authority, they see to it that there is a healthy environment in Germany in which people can live protected as far as possible from harmful environmental effects, such as pollutants in the air or water.


TROPOS- Leibniz-Institut für Troposphärenforschung

TROPOS is an internationally leading facility for tropospheric research heavily focused on aerosols and clouds and their interaction. Additionally, TROPOS is strongly involved in interdisciplinary research pertaining to air quality.

TROPOS records, understands and models the physical and chemical processes of tropospheric aerosols and clouds from the molecular and microscale to long-range transport in areas with varying degrees of pollution.

Througouht the years, TROPOS has worked hand in hand with policy-makers from local to the European level and social communities in understanding and addressing the impacts of atmospheric pollution to health and climate.



ACTRIS is the fundamental European Research Infrastructure for short-lived atmospheric constituents increasing the excellence in Earth system observation and research and providing information and knowledge for developing sustainable solutions to societal needs.
ACTRIS shall establish, operate, and develop a pan-European distributed research infrastructure for short-lived atmospheric constituents. ACTRIS shall provide effective access for a wide user community to its resources and services, in order to facilitate high-quality Earth system research.
