Strategic ozonesonde networks [Thompson et al., 2010] assemble stations and coordinate launch times for a well-defined set of scientific goals. In recent years strategic networks supporting investigations into the upper troposphere and/or lower stratosphere (UT/LS) include: Match, designed to study polar ozone loss; the tropical SHADOZ, initiated for satellite validation and chemical studies (Thompson et al., 2003; ); the IONS series to examine inter-continental transport of mid-latitude pollution [Thompson et al., 2007a; 2008; Tarasick et al., 2009]. SHADOZ (Southern Hemisphere Additional Ozonesonde Network) has provided a wealth of information about stratosphere-troposphere exchange and other processes in the tropical UT/LS (see Fuglistaeler et al., 2009). Nearly 4000 ozone profiles from SHADOZ during 1998-2007 have been interpreted in terms of gravity (GW) or Rossby waves (RW) according to the method of Pierce and Grant [1998] as applied by Thompson et al. [2007a,b]. Wave characteristics for representative SHADOZ sites will be presented, along with related observations from tropical aircraft and satellite campaigns, e.g., TC4 (Tropical Composition, Clouds and Climate Coupling).
