The RDA is not updating this dataset any longer. For data beyond 2011, please see the NCEI web site.
Please note that we have not received the 2010 diurnal and regular monthly means from NCEP, so those means are only available through the end of 2009. Here at NCAR, we are extending the individual parameter/level time series (of the regular monthly means) to the end of 2010 upon request. Please email us if the parameter/level combinations you want are not updated through 2010 in the individual time series.
This dataset has been superseded by ds463.3.
