ANALYSIS of the DISTRIBUTION OF OZONE and LINKS to AVAILABLE DATA SETS.

BACKGROUND:

Until recently, the only systematic measurements of the vertical distribution of ozone were ozonesondes that are launched at various sites around the world.  These data are available from three primary sources, the World Ozone and Ultraviolet Data Centre (WOUDC), the SHADOZ web site, and the Global Monitoring Division (GMD) of NOAA.   I have used these data to describe characteristics of the spatial and temporal distribution of ozone in the papers listed below. The most recent analyses focussed on an analysis of ozone data over Europe (Logan et al., 2012), a climatology for the vertical distribution of oozne in the stratosphere and troposphere (McPeters et al., 2007). I also contributed to an analysis of MLS data for ozone in the tropical upper troposphere led by Nathaniel Livesey of JPL (Livesey et al., 2013).

DATA-SETS:

The monthly mean files for ozonesonde data described in Logan (1999a) can be found here.  Updates to these files for the period 1995-2010 will be posted in 2013.
