| Zusammenfassung |
| A new Laser Induced Fluorescence (LIF) system coupled with an inlet box to thermal
dissociate selected NOY , has been developed at the University of L’Aquila (Italy) and
installed on the British FAAM BAe 146 research aircraft. The L’Aquila-LIF includes 4
detection cells to simultaneously measure profiles of NO2, total Peroxy Nitrates (PNs), total
Alkyl Nitrates (ANs) and HNO3. In summer 2010, the LIF was used in two aircraft
campaigns called RONOCO and SeptEx, in England. RONOCO was a nighttime campaign
focused on the NO3 budget whereas SeptEx was a daytime campaign focused on the
detection of ships and biogenic emissions. In both campaigns were observed very different
environments that range from very clean air conditions, polluted air from big city, such as
London and marine environment affected by sea breeze and chlorine chemistry. Here will be
shown the LIF performances on the BAe 146 aircraft and discussed first results of the
campaigns, focusing on NOX changes due to transport and chemistry in the lower
troposphere and on the NOY budget taking into account the role of PNs and ANs. |
