Prof. McElroy at the Brewer Ozone Spetrophotometer Workshop

Professor Tom McElroy of ESSE will be attending the biennial Brewer Ozone Spectrophotometer workshop in Mazagon, Spain at the end of May this spring.  Approximately 20 Brewer spectrometers will be brought together for maintenance and calibration at the Spanish El Arenosillo rocket range on the Atlantic coast South of Portugal.  McElroy designed the double monochromator Brewer which is gradually replacing the original single Brewer in the global network.  Ozone data and UV spectra collected by the Brewer were used to develop the UV Index, reported in the weather forecast in 25 countries around the world.  May 27 marks the 25th anniversary of the introduction of the UV Index.   McElroy and colleagues David Wardle and James  Kerr are credited with its invention.  There are now more than 200 Brewers in service globally.
