Description

The Stratospheric Water and Ozone Satellite Homogenized (SWOOSH) database is a monthly mean merged data set of vertically resolved ozone and water vapor data from a subset of limb profiling instruments operating since the 1980s. In this presentation, we summarize recent updates and improvements to SWOOSH that were made as part of the forthcoming version 3.0 release. Changes in version 3.0 include updated versions of existing data sets, new sources of data, and additional ancillary information for quantifying uncertainties. We also assess the impact on variability and trends due to the source data updates (e.g., Aura MLS v5.0) and inclusion of new satellite records to SWOOSH from ACE-FTS, SAGE III/ISS, and OMPS-Limb Profiler. We also discuss plans to continue the SWOOSH record following the expected loss of the Aura MLS instrument in coming years, and the potential impacts of this loss on the uncertainty of the SWOOSH merged water vapor and ozone record.
