Improvements to the Stratospheric Water and OzOne Satellite Homogenized (SWOOSH) data set and implications for ozone and water vapor variability and trends | CU Experts

<p>In this presentation, we summarize recent improvements to the Stratospheric Water and Ozone Satellite Homogenized (SWOOSH) database. SWOOSH is primarily a monthly mean zonal mean merged data set of vertically resolved ozone and water vapor data from a subset of limb profiling instruments operating since the 1980s. This presentation details recent updates and improvements made to SWOOSH to include additional sources of data and improve uncertainty estimates. The improvements to SWOOSH include new efforts to better account for uncertainties related to sparse sampling and inconsistent error estimates among different satellite sensors. We also assess the impact on variability and trends of incorporating three new satellite sensors to SWOOSH (ACE-FTS, SAGE III/ISS, and OMPS-Limb Profiler), as well as from including the new Aura MLS version 5 data. With the expected loss of the Aura MLS instrument sometime in the mid 2020&#8217;s, the addition of these new instruments will help continue the SWOOSH record into the future.</p>
