  1. Rob MacKenzie Secondary organic aerosol Aerosols Chemistry Polar stratospheric clouds Tropical dehydration of stratospheric air Effects of air traffic pollution Effects of air traffic pollution Effects of tropical land-use change on climate Clouds Climate

  2. Emission inventories NAEI and TNO Back trajectories BADC Lagrangian Box Model CiTTyCAT Particle chemistry Dry deposition Compared to the NETCEN automated network of PM10 measurements Research interest #1: Modelling the polluted boundary layer e.g. Primary PM10

  3. Full Scale Rochester, March 1998: all components (primary, SOA, SIA) Kathryn Emmerson, PhD, Lancaster, 2002 Sometimes it “works”...

  4. Measured PM10 (40%) Primary PM10 Primary + SOA PM10 Primary + Total Condensable PM10 X Model Results: Rural Rochester R2 has increased from 0.30 to 0.33 with the addition of SOA Concentration mg/m3 March 1998 …and sometimes it doesn’t... Measured PM10 mg/m3 CiTTyCAT PM10 mg/m3

  5. Talking about aerosols... Trying to understand someone who really knows about aerosols... Research Interest #2 The fundamental (classical) physics of small (< 10 m) particles - especially changes of phase

  6. Doug Lowe models these polar stratospheric clouds... …but gets the colours all wrong! % HNO3 time Particle size

  7. Show the movie Rob! Research Interests #3 the upper troposphere and lower stratosphere In-situ measurements of clouds, aerosol, and chemistry. Models of clouds; lagrangian analysis of long-range transport

  8. View from Ellel, NW Lancashire, 19 December 2002 Aircraft produce contrails and perhaps alter cirrus  alter climate Long-term measurements of Cirrus (& contrails) at Hazelrigg

  9. Mission Scientist for... • APE-POLECAT (Arctic) • APE-THESEO (Seychelles) • EuPLEx (Arctic) • TroCCiNOx (Brazil) • …1 month in a beautiful place, worrying about the “weather”, worrying about the ’plane, settling disputes, arguing about money… • …wouldn’t miss it for anything! • (except a new baby)!!!
