  1. BAS ozone monitoring in the Antarctic Steve Colwell British Antarctic Survey

  2. Current capabilities • Rothera • We operate a Systeme d‘Analyse par Observation Zenithale( SAOZ) in our optical facility. • The data is transferred back to Cambridge on a daily basis where it is processed and archived at the World Ozone and Ultraviolet Radiation Data Centre (WOUDC). • A daily Character form for the Representation and EXchange of data (CREX) messages is sent to the UK Met Office for distribution on the Global Telecommunication System (GTS). • We launch radio-sondes 4 times per week.

  3. Current capabilities • Halley • We operate a SAOZ in a heated box on the roof of the main station. • The data is transferred back to Cambridge on a daily basis where it is processed. • We also operate a Dobson ozone spectrophotometer. • The data is transferred back to Cambridge on a daily basis where it is processed and archived at WOUDC. • A daily CREX messages is sent to the UK Met Office for distribution on the GTS. • We launch radio-sonde’s daily. • Halley and Rothera radio-sonde systems have ozone-sonde capability

  4. Historical observations • Halley • Dobson spectrophotometer 1956 - present • SAOZ 2013 - present • Rothera • Bentham spectroradiometer from 1997 until 2012. • SAOZ 1996 - present • Faraday (now Vernadsky) • Dobson spectrophotometer 1957 – present • SAOZ 1990 -1995 • King Edward Point (South Georgia) • Dobson spectrophotometer 1971 - 1982

  5. Research • Work is being carried out looking at the influence of the ozone hole on the Southern Annular Mode (SAM) and also its affect on Antarctic sea ice. • High resolution modelling of polar stratospheric clouds over the Antarctic Peninsula.
