Paper Abstract

During the STREAM98 campaign conducted from Timmins (Canada) in July 1998, simultaneous airborne measurements of chemical tracers were performed using a Cessna Citation II twinjet as carrier platform. We present an intercomparison of N2O measurements using an in-situ GC (University of Frankfurt/Main, Germany) and a tunable diode laser instrument (TRISTAR) operated by the Max Planck Institute for Chemistry, Mainz, Germany. The duty cycle of the GC is one second measurement per 120 s interval, whereas the sampling rate of the TDLAS is 1 Hz. Both instruments are in situ calibrated using working gas standards traced against primary standards provided by NOAA. The maximum deviation between the two independent measurements of N2O is less than two years, which is of the order of the uncertainties of both instruments.
