20th Century Reanalysis Monthly Composites

20th Century Reanalysis fields for November and December 2010 have been regenerated due to a misspecification of the sea surface temperature fields as of 25 May 2012. All derived files have been recomputed as of 18 June 2012. The re-run is supported by the US Department of Energy Office of Science

Plot seasonal composites (averages) of the mean or anomalies (mean - total mean) of variables from the 20th Century Reanalysis V2 reanalysis. 20th century reanalysis data is available from Jan 1871 to Dec 2010.

? Which variable? Level?
? Beginning month of season: Ending month:
? Enter years for composites (from 1 to 16): e.g. 1972. For seasons that span a year (e.g. DJF), please enter year of the LAST month.

To subtract one set of years from another, use a minus sign (-) before the years that are to be subtracted.


? OR Enter range of years: to (optional minus to )
? OR List of years: Enter filename:
? OR Years from values in Time Series:
