Selected Projects

  1. Bullet2005-2007 ( Contribution to the EC(Nest Insight)-Project, ANTISTORM, “Anthropogenic Aerosols Triggering and Invigorating Severe Storms”; Outcome: “ANTISTORM provided one of the first insights into the science of 'man- made' weather in Europe. In fact, some weather phenomena may not be as natural as commonly thought. Recent studies suggested that man-made particulate pollution can substantially increase the severity of certain storms or even trigger their inception.”

  1. Bullet 2019—present (Eco-Serve): Contribution to point forecasts of air pollution, weather and solar. Currently PM2.5 (wet vs dry), visibility, AOD and more.

    -- Daily AOD observations : Berlin, Freiburg and Karlsruhe (all Germany).
    -- Meteogram -- 5 day forecasts : Hamburg, Oldenburg, Hannover,
  2. München, Würzburg and Freiburg.
  3. -- 5 day PM & visibility forecasts : Hamburg Fuhlsbüttel (air port).
    -- Extended MOSMIX forecasts : Hamburg Fuhlsbüttel (air port).

    Our point forecasts are based on forecasts of CAMS PM2.5, DWD MOSMIX, meteo forecasts and EEA PM observations, which all serve as input for our additional sophisticated point computations. Work is in progress.

  1. Bullet 2024—present (HORIZON Europe: CAMAERA (101137682)): CAMS AERosol Advancement. CAMAERA will provide, for the Copernicus Service for Atmosphere Monitoring, strong improvements of the aerosol modelling capabilities, of the assimilation of new sources of data and of a better representation of secondary aerosols and their precursor gases. To achieve this, the project will develop new prototype service elements in close collaboration with the CAMS service providers and other projects.
