Task Group 1
AQ Protocols & EU Policy Support
User Inputs
 User information needs – data products and
specifications
 User Segments – who are the users?
 Policy foundation – what is the policy?
 Science review – what are the science
questions?
 Strategy for Integrated Observing System
User Needs
 Wide range of users with different needs
 User needs are not only data may also be an integrated product
– Additionality – what can space add value to
 Tropospheric ozone and NO2
 PM2.5/AOD warnings
 Some VOC as a proxy for benzene?
 Use ground-based measurements in NRT on a European scale.
– Country to country availability
 Sectorisation of pollutants – define strategies
 Mapping of pollutants – higher resolution than ground stations
(chemical weather, O3, PM, SO2, NOx, benzene (VOCs), CO)
 Accidental releases – where has it come from?
 Consequences of any abatement measure (likely outcome, cost
estimate, total benefit)
 Forecasting – real time and information models
 High temporal and spatial resolution from satellite systems –
synergistic use of multiple satellites instruments
 What are the major uncertainties?
Spatial and temporal requirements
 As much as possible
– Trade-off model and satellite
 Role for assimilation
– How many observations do we need?
– Would we need operational satellites? or could a
science mission lead to a step-change improvement
model that may out mode it?
– What is the timescale for models to fall out kilter
– Quantitative assessment of difference
– Every overpass may not provide data
User segment
 Public awareness
– information
 Compliance
– exceedences
 Technical basis for abatement
– Models
 Effects community
– Habitats, health
 Research community
– Scientific basis
Policy Foundation
 Based around AQ-FD & CLRTAP
 Fulfilment of directives is a driver
 What is the next step?
– CAFÉ – improve revision of directives (PM and O3)
 PM10  PM2.5 (WHO) – in addition
 Background concentration O3
–
–
–
–
Urban AQ (NO2 hot-spots in streets) & exposure in cities
Integrated assessment – Habitats directive and health issues
Solvents directive (VOC)
Hydrogen – hydrogen economy (way out?)
Science review
 Science of applications
– How do we turn space products into useful user products
 Chemical climatology – plume monitoring integrated tool
for source-receptor/ emitter receiver/ source apportionment
analysis
– Corroboration of ground data
– PM10, aerosol, CO, HCs, O3 precursors, tO3 from total column
 Dust retrieval over bright surfaces – health
 3-D fields for model validation
– Delivery of in-situ aircraft in real-time
Strategy
 Would like to have a Chemical Weather
System (Long term goal).
– Have an equivalent system for AQ to EMCWF
– Assimilate relevant data into a model and
produce products for use by national agencies
– Global scale activity for a European product
 To investigate whether GMES-GATO &
IGACO provisions meet this.
