WOUDC ground-based TCO

The World Ozone and UV Data Center (WOUDC) provides an historical archive of total column ozone (TCO) measurements from a number of instruments. These data are available here. However, the data are provided as CSV files (although not always) and with a wide range of data formatting. There are on the order of 80,000 files comprising the database. To make the database more machine readable, we have created NetCDF files (one per site) of this database that are self-describing and consistent across all sites. 

To access the database, or to be kept informed of updates to the database, please email Greg Bodeker at I am not routinely updating these NetCDF files so if you find that the files on the Bodeker Scientific FTP server are not as up to date as you would like them to be, please email me and I will update them.
