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
