The researchers present and compare formaldehyde measurements obtained in spring 1998 in the Milan area by two different techniques, a long-path UV visible absorption spectroscopic system (DOAS) and a sampling technique (DNPH). Despite having different spatial and time resolution, DOAS and DNPH measurements of formaldehyde compared fairly well. The formaldehyde concentration time series retrieved from DOAS were analyzed with respect to meteorological conditions, particularly regarding heterogeneous removal processes, and the concentration of other air pollutants associated with formaldehyde emission and production. Pollutant dynamics calculations, made with a 3D photochemical grid (Eulerian) model over a wide spatial domain, were compared to the measurements and provided a basis for the interpretation of the formaldehyde measurements performed during an intensive observation period. |
