Programme

  1. Model evaluation and quality assurance – model validation, model intercomparisons, model uncertainties and model sensitivities.

  2. Environmental impact assessment: Air pollution management and decision support systems.

  3. Use of modelling in support of EU air quality directives, including FAIRMODE activities.

  4. Parametrization of Physical Processes and Mathematical Problems in Meteorology and Air Quality Modelling.

  5. Urban Scale and Street Canyon Modelling: Meteorology, Air Quality and Passive Control Systems.

  6. Use of modelling in health and exposure assessments.

  7. Inverse dispersion modelling and source identification.

  8.  Modelling air dispersion and exposure to accidental releases.

  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.




    There are also 3 special sessions in addition (harmo20_special_sessions.pdf):

SS1- Microscale modelling for ambient air
quality directives


A consultation within the FAIRMODE community made clear that micro-scale
modelling is used more and more in a policy context to support the
implementation of the Ambient Air Quality Directives (AAQD). One of the key
open issues that was identified is the derivation of annual statistics (such as an
annual average or percentiles) based on micro-scale modelling results. The aim
of this session is on one hand to understand how micro-scale modellers post-
process their data to obtain annual statistics that are relevant for the AAQD and
on the other to understand which input would be necessary for a potential inter-
comparison of these methodologies. Indications for contributing to this special
session will be circulated in due time.

Scheduled agenda: 3 hours
Part 1 - PRESENTATION: volunteering participants briefly present their
methodology and answer specific questions following a given template provided
by the organisers.
Part 2 - DISCUSSION: open discussion to understand if a potential inter-
comparison exercise could be organised with the goal to recommend best
practices.

 

SS2 - A CTM intercomparison platform to assess model
sensitivities to emission changes

 

The sensitivity of model responses to emission reductions when input data
(emissions, meteorology…) or the model itself are changed is recognised as an
important issue to be addressed in the context of FAIRMODE. It is indeed a key
element to ensure robust policy making. The scope of this activity is to assess,
discuss, explain and minimize model (mostly CTM) discrepancies with the
support of a dedicated modelling inter-comparison platform. During this
dedicated HARMO session, we will present the design of the inter-comparison
platform, show some preliminary results and discuss ways forward.

Scheduled agenda: 2 hours
Part 1 - MOTIVATION AND METHOD: an overall presentation to explain why
we set-up this platform, why we came out with this solution to approach the
issue, what do we want to check.
Part 2 - PRESENTATION OF THE PLATFORM: introduction to the overall set-
up and description of preliminary results achieved.
Part 3 - DISCUSSION: open discussion and planning of next phases.

 

SS3 - CORONA Virus Covid-19: effects of lockdown on air
quality, possible connections with air pollution.


The spread of Corona Virus Covid-19 in the first months of 2020 led to the
lockdown in several Countries worldwide. There are two main scientific issues
in the field of air pollution, which scientists are expected to investigate: how and
how much the lowering of the emissions due to the lockdown had an effect on
the air quality; whether and how the virus may be transported by aerosols and
spread in the atmosphere, outdoor and indoor, and how this can be modelled.
Contributions to this special session will be collected in early June, re-opening
the abstract submissions.

Scheduled agenda: 3 hours
Part 1 - INTRODUCTION TO THE SESSION: a presentation of the actual
situation and of the air-pollution items related to the Covid-19 spread.
Part 2 - PRESENTATIONS: oral and poster contributions of (preliminary)
studies performed.
Part 3 - DISCUSSION: open discussion and recommendations on how the air-
pollution community may contribute to the understanding of the phenomenon.
