Description
The recent "drop-off" problem with ozonesondes in the global network has also affected a majority of sites in the Canadian network. Despite considerable effort the issue has not yet been resolved, and the data cannot yet be reliably corrected. However, there is evidence that only some profiles are biased and so it may be possible to filter time series, flagging doubtful data. This problem highlights the need for routine intercomparison of global network observations, in order to assure the quality and consistency of these data.
