Air pollutants variations recorded

In addition to the measuring of NOx degradation, in LIFE Photoscaling project, these contaminants and other ones are constantly measured by using two types of meters:

The first one (in the left of the picture) reveals the live concentration of NO, NO2, O3 and, moreover, relative humidity and temperature (both also registered by weather stations).

The second one (in the right of the picture) keeps a record of organic volatile compounds (COVs) and organic semi volatile compounds (SCOVs).
