Comparing measurement date on impurities in the air important

The Finnish Meteorological Institute has studied the concentration of volatile organic compounds in the air together with a Swiss research group and the University of Helsinki. In the study, a comparison was carried out between the concentration results from four different instruments. The study revealed that there are still significant uncertainties in measuring methanol.
