The Conference is devoted to Laura Venegas and Nicolás Mazzeo and also to Jan Kretzschmar


The following topics were covered during the conference:
  • H20-1 - Model evaluation and quality assurance – model validation, model intercomparisons, model uncertainties and model sensitivities
  • H20-2 - Environmental impact assessment: Air pollution management and decision support systems
  • H20-3 - Use of modelling in support of EU air quality directives, including FAIRMODE activities
  • H20-4 - Parametrization of Physical Processes and Mathematical Problems in Meteorology and Air Quality Modelling.
  • H20-5 - Urban Scale and Street Canyon Modelling: Meteorology, Air Quality and Passive Control Systems
  • H20-6 - Use of modelling in health and exposure assessments
  • H20-7 - Inverse dispersion modelling and source identification
  • H20-8 - Modelling air dispersion and exposure to accidental releases
  • H20-9 - Highlights of past work. Session devoted to reviews and to prominent scientists and ‘golden papers’ of the past, which have still relevance and should not be forgotten
  • H20-10 - Special Session 1- Microscale modelling for ambient air quality directives
  • H20-11 - Special Session 1 - A CTM intercomparison platform to assess model sensitivities to emission changes
  • H20-12 - CORONA Virus Covid-19: effects of lockdown on air quality, possible connections with air pollution
