 Correlation between mass and haze
 Percentage of covered surface

 Percentage of covered surface 
LIMESTONE
 No mass data (too much loss of material during the ship)
 Measurement of the reflectance
 Increase of the reflectance (already observed in the first stages) except for Paris and Berlin

 Correlation between % covered surface and % reflectance
 No clear correlation

 Mass: a lot of uncertainties

 Reflectance:
 Increase or decrease of the reflectance

MARBLE
 Correlation between % reflectance change and % covered surface :
 Raman analyses of black spots
Correlation between materials
 No clear correlation
 Too short exposure time for stone samples?
Summary and future prospects
 Pursuit of the temporal trend of glass soiling
 New set of data to test the dose-response functions
 For the stone samples, the exposure time seems too small
longer campaigns (to be discussed) ? Local analyses ?
Next steps (ion chromatography for soluble species and ICP-MS for trace metals)
