SUMMARY:Ground-based and aircraft LIF systems using thermal dissociation t
 echniques: instrument description and field campaigns results - Dr Piero D

DESCRIPTION:At the Centre of Excellence CETEMPS of the University of L’A
 quila (Italy) we developed a Laser Induced Fluorescence (LIF) for direct m
 easurements of NO2 and measurements of Peroxy Nitrates\, Alkyl Nitrates an
 d HNO3\, after thermal dissociation into NO2. The LIF system\, unique in E
 urope at the moment\, was deployed in the Borneo forest during the OP3 cam
 paign (2007) and installed on the BAE-146 aircraft of the FAAM. In summer 
 2010 the LIF was used to make observations on board the BAE-146 for the RO
 NOCO campaign. In this seminar will be illustrated the LIF technique\, the
  development of the instrument and some tests. Results of recent ground-ba
 sed and aircraft campaigns will be shown\, together with future possible a
 pplications of the LIF technique for the observation of other species and 
 possible contribution to answer some of the open questions on the atmosphe
 ric chemistry and atmospheric compositions changes.
