The Southern Hemisphere Additional Ozonesondes (SHADOZ) network, jointly operated by NASA-Goddard Space Flight Center (GSFC), NOAA’s Global Monitoring Lab (GML) and international partners, collects and archives ozonesonde-radiosonde data records for 14 operating stations in the tropics and subtropics. There are now >9200 ozone and pressure-temperature-humidity (P-T-U) profiles with 100m vertical resolution at the SHADOZ archive (https://tropo.gsfc.nasa.gov/shadoz) with data from 1998-2022. There are several stations with 1-2-decade long records including NOAA-affiliated stations: Hilo, Samoa, and Fiji. The focus of this presentation is a 2022 update on the SHADOZ Data Archive (https://tropo.gsfc.nasa.gov/shadoz/Archive.html) including: (1) the introduction of Digital Object Identifiers (DOIs) for SHADOZ station datasets for data users, (2) recent efforts in metadata collection for optimal data processing, and (3) the availability of recent SHADOZ-derived tropical ozone trends from Thompson et al. (2021). We also report on the success of hosting virtual regional SHADOZ station meet-ups in 2021 and 2022, organized by the NASA-GSFC team, to foster improved communication with station Principal Investigators and staff. This presentation summarizes our overarching goal of maintaining the continuity of long-term global ozonesonde records and ensuring that the best quality data reach end users.
