CAMAERA at the ICAP 2024 meeting

The International Cooperative for Aerosol Prediction (ICAP) is an international forum for aerosol forecast centers, remote sensing data providers, and lead systems developers to share best practices and discuss pressing issues facing the operational aerosol community. The 14th working group meeting took place between 28th and 30th of October in Helsinki (Finland).

Many partners of the CAMAERA consortium attended the meeting and presented the latest results:

  • Samuel Remy, from HYGEOS, presented pathways for longer term evolution of the global CAMS system (IFS-COMPO) resulting from the work of CAMAERA and CAMEO projects. His talk focused on the integration of machine learning techniques in the global CAMS system and exploratory ensemblist approaches for atmospheric composition (figure below). His presentation is available here.
  • Mikhaïl Sofiev, from FMI, introduced a new parameterization of whitecap fraction, derived as a quadratic fit from remote sensing observations, to improve the sea-salt source in the chemistry-transport model SILAM. His presentation is available here.
