Work package D-INSITU 1
“Acquisition of Near-Real-Time unvalidated data”
NRT station representativeness evaluation

3. Objective
Criterion definition for representativeness flags assignation.
Function of:
emission type (traffic, industrial);
station type (urban, rural, isolate);
validated data availability (climatical and pollution):

4. Data involved for representativeness study
Topographical component (altimetry map with 30 m resolution, CLC 2006 map, population repartition using ortophotos with < 1m resolution) – after GEOmon Project - Global Earth Observation and Monitoring of the Atmosphere
Climatological component (wind, temperature, pressure, cloudiness, etc. – measured and boundary layer parameters computed - e.g. mixing height);
Air quality component (emission inventory):
emission sources location and parameters;
imission measurement station location and type;
emission/imission inventory.
Imission dispersion maps using OML model.

5. Methods Digital Elevation Model Dispersion climatological model (OML);
Use of GIS for common geo-referencing of all available data

6. Proposed steps for flags definition
Climatological analysis of pollutants local dispersion - at very high resolution
To compute the dispersion the following data are needed:
- Altimetry;
- Land cover classes (with very high resolution) used to compute the roughness and other parameters;
- hourly data are extracted for wind ( ), temperature, pressure, cloudiness, etc. from the weather stations;
- statistical analysis on speed threshold, direction frequency / other parameters.
II) Correlation between climatological dispersion and the affected area
- Correlation with population;
- Correlation with affected land cover class (arable, forest, pasture etc.)

13. Questions
1. Data retrieval (from MACC or NEPA ?) of the info related to air quality data / pollution sources locations, measurement stations locations, measurement station type?
2. Any suggestions from already implemented methodologies in MACC are very welcome;
3. Are there already defined criteria for reprezentativeness?
