Trace gas and aerosol data sets from DLR aircraftcampaigns - of use for validation in GEMS?Andreas Minikin, Martin Dameris, Heidi Huntrieser, Andreas Petzold, Hans Schlager, Ulrich SchumannDLR, Institute of Atmospheric Physics, Oberpfaffenhofen, Germany(associated partner in GEMS)

Trace gas & aerosol in situ measurementswith the DLR Falcon• altitude range: up to 12 km (190 hPa), FT & UT! • data sets from different experiments / different regions:
mainly mid-latitudes, but also polar, tropics, ferry flights• limited temporal representativeness:
(an "average" campaign: 3-4 weeks, 30-60 flight hours, 8-12 flights)• but: accurate measurements, high vertical resolution
Falcon in situ measurements (data not for all campaigns available)trace gases humidity, CO, ozone, NO/NOy, CO2
aerosol number concentration (ultrafine, Aitken, accumulation mode), number size distribution, non-volatile particle fraction, (absorption coefficient)
cloud microphysics
number density, size distribution, extinction
atmospheric state
temperature, pressure, wind, aircraft position
