Who has looked at monitoring data? Which
cities? Monitoring data warnings can be looked
at whats new instead of updating the files
5Measurement technique
6- Series of 3 Graphical Analysis tools
Measurements, Base case, Deltas - Which are inter-dependent
- To be made available to the City-Delta community
(to be discussed) - Cd_station objectives
- Overall visualisation of whats available for the
different cities - Visualise main characteristics of each
city/station - Choice of more interesting stations for
evaluation step - Detection of unexpected measurements
- City/city comparison
7Validation Selection of 9 stations
- O3M Station where max O3 (over 6 months) is
reached - O3m Station where the lowest maximum O3 (over
6 months) is reached - MO3M Station where the 6-months mean O3 is
highest - MO3m Station where the 6-months mean O3 is
lowest - PM Stations where PM10 measurements are taken
- NO2 Higher and Lower annual mean NO2 stations
- Spatial representativity (NNI)
- Data Availability
- Station type diversity (urban-suburban-rural)
