dc.description.abstractThe recent Assessment of Standard Operating Procedures for Ozonesondes 2.0 (WMO/GAW Report #268) addressed questions of homogeneity and long-term stability in global electrochemical concentration cell (ECC) ozone sounding network time series. Among its recommendations was adoption of a standard for evaluating data quality in ozonesonde time series. Total column ozone (TCO) derived from the sondes compared to TCO from Aura's Ozone Monitoring Instrument (OMI) is a primary quality indicator. Comparisons of sonde ozone with Aura's Microwave Limb Sounder (MLS) are used to assess the stability of stratospheric ozone. This paper provides a comprehensive examination of global ozonesonde network data stability and accuracy since 2004 in light of the sudden post-2013 TCO “dropoff” of ∼3%–4% that was reported previously at select stations (Stauffer et al., 2020, https://doi.org/10.1029/2019GL086791). Comparisons with Aura OMI TCO averaged across the network of 60 stations are stable within about ±2% over the past 18 years. Sonde TCO has similar stability compared to three other TCO satellite instruments, and the stratospheric ozone measurements average to within ±5% of MLS from 50 to 10 hPa. Thus, sonde data are reliable for trends, but with a caveat applied for a subset of dropoff stations in the tropics and subtropics. The dropoff is associated with only one of two major ECC instrument types. A detailed examination of ECC serial numbers pinpoints the timing of the dropoff. However, we find that overall, ozonesonde data are stable and accurate compared to independent measurements over the past two decadesen_US
dc.description.sponsorshipThe data analysis that contributed to this paper was part of an ongoing effort by the ASOPOS 2.0 Panel and ozonesonde colleagues to quantify global ozone-sonde network data quality and to solve the TCO dropoff. The authors express appreciation to the Network for the Detection of Atmospheric Composition Change (NDACC) Ozonesonde Working Group and Steering Committee. The ozonesonde data collected and presented here represent the combined effort of hundreds of ozonesonde community members around the globe, for which we are grateful. We are also grateful for the open communication from EnSci to help solve the source of the ozonesonde TCO drop. Funding for this work was graciously provided through support of SHADOZ and NDACC by the NASA Upper Atmosphere Research Program and Upper Atmospheric Composition Obser-vations Program (UARP and UACO; Dr. Kenneth Jucks program manager) to NASA/GSFC (R. M. Stauffer, PI). Special thanks to Universidad San Francisco de Quito (USFQ) and to Dr. María Cazorla, PI, for providing and making public the ozonesonde data from Ecuador (Cazorla et al., 2021).en_US
