  1. Consortium Start: 1994 First measurements: 1997 Lund Joined 1995 First measurements: 1999 2 PhD (Papaspiropoulos, Nguyen) 11 Research groups Germany (6) France (1), Netherlands (1) Sweden (1), Switzerland (1) UK (1) + Lufthansa CARIBIC – Sampling from Passenger Aircraft VR project (3 y): Global scale experimental studies of the aerosol chemical composition in the upper troposphere and the lowermost stratosphere – focus on nano structures Civil Aircraft for Regular Investigation of the atmosphere Based on an Instrument Container

  2. Aircraft LH A340-600 D-AIHE

  3. Inlet water inlet video camera trace gas inlet aerosol inlet

  4. O3 NOy CO Instrumentation 1.6 m 1.5 t

  5. Trace gases In situ CO O3 NOy H2O Acetone, Methanol Air samples GHG Halogenated compounds Isotopes Special O2 DOAS (NO2, O3, BrO, HCHO) Aerosol Size distribution 3 CPC (cutoff 4, 12, 18 nm) OPC (100 nm – 5 µm) Samples (100 nm – 2µm) Quantitative analyses PIXE (S and heavier) PESA (H(?), C, N, O) Single particle analyses TEM EFTEM Meteorology (trajectories etc.) CARIBIC Measurements

  6. Results – Particulate Sulfur

  7. First PESA Results

  8. Results – Single Particle Analysis TEM and EFTEM on stratospheric particle

  9. Short term (this year) Develop H analysis Undertake large number of H, C, N, O analyses Sulfur climatology Influence of deep convection on UT/LS aerosol Longer term Methods to classify the carbonaceous component Climatology H, C, N, O Production of carbonaceous aerosol in the stratosphere Revisit single particle analysis Plans
