Johannes Flemming

Principal Scientist
Copernicus Department, Copernicus CAMS Services, CAMS Development Section

Summary:

Johannes Flemming is a Principal Scientist in the development section of the Copernicus Atmosphere Monitoring Service (CAMS) at ECMWF. Johannes's role is to coordinate the development of components on atmospheric composition in the Integrated Forecasting System (IFS) that are used for CAMS. The development of these components is carried out in collaboration between external partners such as KNMI and Météo-France, as well as the CAMS development section and the research department at ECMWF.  Johannes is also responsible for the transition of the CAMS developments to their application in the operational CAMS Near-Real-Time forecasting system. 

Professional interests:
  • Modeling of chemistry in the troposphere and the stratosphere
  • Modeling of wet and dry deposition of gases and aerosols
  • Trends in atmospheric composition, in particular for carbon monoxide and tropospheric and stratospheric ozone
  • Ozone hole monitoring
  • Dispersion of ash and sulfur dioxide after volcanic eruptions
  • The impact of atmospheric composition on weather forecasting
  • Improving the computational performance of the CAMS configuration of the IFS
Career background:

Johannes studied meteorology in Berlin and completed his doctoral thesis (summa cum laude) on the topic of data assimilation of air quality observations in a regional model. He started working at ECMWF in 2004 working in the HALO, GEMS and series of MACC projects, and since 2015 in CAMS.
