High Precission NO2 and NOx measurements with the ICAD instrument during s-b-s campaign Hohenpeißenberg 2016 — Denis Pöhler1, •Erik Lutz1, Martin Horbanski1, Johannes Lampel1, and ACTRIS s-b-s Team2 — 1Institute of Environmental Physics, Uni Heidelberg — 2ACTRIS s-b-s intercomparison NOx 2016 Team
Nitrogen Oxides (NOx) play a major role in air pollution and atmospheric chemistry. Beside health effects they influence e.g. acid rain, ozone and oxidation capacity. But precise NO2 and NOx measurements are still difficult. During a ACTRIS side by side (s-b-s) inter-comparison campaign at the Meteorological Observatory Hohenpeißenberg (DWD) 2016 the performance of different instruments for NO2, NO and NOx were investigated under natural and artificial conditions. We present results of our ICAD Instruments for direct optical NO2 and NOx measurements. The inter-comparison demonstrates excellent performance of ICAD in terms of accuracy and drift. Also different conditions like different humidity's, temperatures and possible interfering gases do not influence the measurement result.
