Presentation Transcript

  1. WP3.1 Radiative closure (EUCAARI)

  2. Radiative closure • Use in-situ measured (and inferred) aerosol optical properties and radiative transfer code to model fluxes • Compare with broad band radiometer measurements on aircraft • To date: • Identification of suitable flights (B362 and B374) • Assessment of accuracy of BBRs and need for pitch/roll corrections • Preliminary calculations with Edwards and Slingo (1996)

  3. B362 May 6, 2008

  4. B362

  5. B362

  6. B374 – Radiation flight with CMET May 14, 2008

  7. τ(dry)=0.24 τ(dry)=0.21

  8. BBR data from B374

  9. Aerosol hygroscopicity during B374 Wet nephelometer provides f(RH), ϐ/ ϐ0 Need D/D0 for full mie scattering code (Tang 1997 growth not appropriate)

  10. Further work • Still to do…. • Radiative closure with BBRs for aerosol runs (wet aerosol – properties now available from use of wet neph data) • Analysis of orbits/SWS/SHIMS data (to be done by Debbie O’Sullivan, Met Office) • More radiation flights?
