| 520 | _ | _ | |a Some ultra trace gas species present in the upper troposphere and lower stratosphere(UTLS) region at low part-per-billion and part-per-trillion mixing ratios are known to havea major effect on atmospheric chemistry and climate. Chlorine and bromine species causingstrong ozone depletion and sulfur dioxide (SO$_{2}$) driving aerosol formation processes of high relevance to the global radiative budget are prominent examples. Nitric acid (HNO$_{3}$)is another species, which is quite important for particle formation and denitrification processes. In order to fully understand and reliably model the involved processes for climatepredictions, spatially highly resolved in-situ measurements of these species are needed. Therefore robust instruments are required that can perform very sensitive and accuratemeasurements of ultra-trace species in the extremely challenging UTLS environment from balloons or favorably high-flying aircraft, which impose stringent mechanical and electrical constraints. Here I describe the set-up, test, characterization, deployment, data analysis, and preliminary results of the new FunMass instrument tailored to the deployment on the high-flyingresearch aircraft M-55 Geophysica. FunMass utilizes the established techniques of chemical ionization mass spectrometry (CIMS) in an unprecedented package pairing measurementsensitivity and accuracy with high versatility at reasonable instrumental weight and dimensions. FunMass was set up based on a laboratory prototype [1]: the concept of its transferstage with an ion funnel and its dielectric barrier discharge (DBD) ion source was adapted for the airborne version of the instrument. The ion funnel improves the sensitivity of the instrument at least by one order of magnitude and the DBD ion source is an excellent replacement for the logistically very challenging radioactive ion source, which is widely used for CIMS. A big advantage of the TOF-MS technique for airborne measurements is that it is capable of fast and simultaneous acquisition of full mass spectra and therefore measurements of many different ion species, which is very important since flight hours of research aircraft are a very limited resource [...] |
