Abstract:
Ozonesonde data support satellite validation, model assimilation and evaluation as well as studies of atmospheric dynamics. Strategic ozonesonde networks coordinate and schedule launches in a fixed region to answer specific questions (Thompson et al., 2011)*. We have organized five such networks in the past 15 years. Most of this talk will focus on the Southern Hemisphere Additional Ozonesondes (SHADOZ; ) network that consists of a dozen tropical and subtropical stations, with 2-4 launches monthly. An overview of SHADOZ origins and workings will be given along with illustrative findings in the troposphere and stratosphere. In campaign-class strategic networks daily launches look at ozone short-term variability to complement NASA aircraft missions. Examples from the 2013 SEACIONS (Southeastern American Consortium for Intensive Ozonesonde Network Study), from the SEAC4RS campaign, will be presented.
