CAVIAR – Continuum Absorption by Visible and Infrared Radiation and its Atmospheric Relevance

Status

Keith Shine Department of Meteorology, University of Reading

September 2010

Reminder of Overall Schedule

• Formal start of CAVIAR: 1 October 2006• Original end date: 30 September 2010• New end date: 30 June 2011• Most CAVIAR PDRA’s and PhD’s will

finish in late 2010/early 2011• Final report due: 29 September 2011• We are now roughly at month 48

(“frame of reference” depends on when students and PDRAs started)

Reminder of structure 1

line-by-line radiative transfer models

existing continuum models

existing spectral line databases

targeted lab measurements

field campaigns

Instrument upgrades and calibration

dimer model development

Royal Society Meeting

• Led by Jonathan Tennyson• “Water in the gas phase” (both

atmospheric science and astrophysics)• 13 to 14 June 2011 at the Royal

Society’s new out-of-town Kavli Centre in Buckinghamshire

• Good representation of CAVIAR speakers and will lead to special issue of Philosophical Transactions of the Royal Society

Key things for today

• How close are we to being able to perform a synthesis of theory, lab and field measurements for the CAVIAR continuum?

• What are plans for papers?• What further meetings do we need

to provide consolidation of our achievements?
