NCAR/EOL Quality Controlled Radiosonde Data: SAVANT 2018


The Stable Air Variability and Transport (SAVANT) field campaign investigated the effects of converging shallow cold air drainage and background flow on aerosols transport and dispersion. From 15 September to 15 November 2018 two integrated sounding systems (ISS) were deployed at two locations near Champaign, IL. 

At the Homestead site (ISS1), 41 successful radiosondes were launched during the campaign. Soundings were launched on select days for the duration of the campaign, with up to five soundings, which were typically launched in 2-hour intervals.

The distance between the radiosonde launch site and the second ISS site (Farm Field site) is approximately 4.5 km.
