Dear Todd Mitchell,

thank you for your interest in my QBO data set. Below you will find
the time series of 30 hPa mean monthly zonal winds from 1953 to the
present. You may include these values into your Web page but I would
appreciate if you would add the following references:
Naujokat, B.: An update of the observed quasi-biennial oscillation
of the stratospheric winds over the tropics. J.Atmos.Sci., 43,
1873-1877, 1986.
This paper describes the data, uncertainties in the early years due
to the lack of daily data, the change of reference stations, and the
general features of the QBO.
Together with my collegue Christian Marquardt, we have presented a new
update at the First SPARC General Assembly at Melbourne, 1996:
Marquardt, C. and B. Naujokat: An Update of the equatorial QBO 
and its variability. 
You can find an extended abstract in the Proceedings WMO/TD-No.814,
volume 1, 87-90, 1997.

A link to our Web page (http://strat-www.met.fu-berlin.de/) would be
nice but not necessary. We don't offer the QBO data there. You could
include my email address (naujokat@strat01.met.fu-berlin.de) for people
who need the complete data set. A time-height section (constructed by
Christian Marquardt) can be down-loaded through the internet by:
ftp://strat.met.fu-berlin.de/pub/marq/qbo 

With best regards 
Barbara
