Global map of around 60 active ozonesonde sites. Green dots mark the stations with homogenized data available at the HEGIFTOM ftp-server.

Bar plots showing the time range of available homogenized ozonesonde records. Stations marked with * consist partially of Brewer-Mast ozonesonde data (Uccle, Payerne, dashed lines) or entirely (Hohenpeissenberg). The Brewer-Mast data of Uccle and Payerne is not available at the HEGIFTOM ftp-server, but should be downloaded from either WOUDC or NDACC.
