摘要: Abstract An Incoherent Broadband Cavity Enhanced Absorption Spectroscopy (IBBCEAS) setup has been developed to simultaneously monitor temporal profiles of nitrate radical (NO3), nitrogen dioxide (NO2) and ozone (O3) concentrations in the atmosphere. The IBBCEAS performance was tested an atmospheric chamber (8 m3) at room temperature (296±2) K dry conditions (RH NO3, NO2 O3 were recorded during NO2+O3 reaction compared those calculated from chemical simulations. experimental simulated data good accordance demonstrate that is effective technique in-situ real time multiple species (NO3, O3). This presents sensitivity resolution required for measurements atmosphere (both indoor outdoor) also a large potential laboratory studies simulation chamber. To our knowledge, this first instrument used follow NO2, reactions.
