1. CAVIAR – Continuum Absorption by Visible and Infrared Radiation and its Atmospheric Relevance How on schedule are we? Keith Shine Department of Meteorology, University of Reading September 2009

2. 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 PDRAs and PhDs will finish in late 2010/early 2011 Final report due: 29 September 2011 We are now roughly at month 36 (frame of reference depends on when students and PDRAs started)

3. 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 dimer model refinement new continuum model impact on understanding of atmospheric processes, incl climate and remote sensing preparation of continuum model for community use synthesis refinement of line database Rough Guide: Green: On original schedule Amber: Somewhat behind original schedule Red: Limited activity so far possible
