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 water vapor data that were made as part of the current version 2.7. Changes include updated versions of existing data sets, new sources of data, and ongoing efforts at improvements for better quantifying uncertainties.
One of the major changes in SWOOSH v2.7 is the switch to using version 5 of Aura MLS data, whereas in previous versions of SWOOSH Aura MLS version 4.2 data were used. We discuss the impact on interannual variability and trends due to the Aura MLS version change. Finally, given the recent reduction in Aura MLS water vapor data sampling and impending loss of Aura MLS in the coming years, we discuss the impacts to the SWOOSH record and future plans to mitigate the loss of this critical data set.
