20th Century Reanalysis Daily Composites

Additional variables are now available for the ensemble means.

Plot daily composites (averages) of the mean or anomalies (mean - total mean) of variables from the 20th Century Reanalysis reanalysis and other datasets. 20th century reanalysis data is available from Jan 1836 to Dec 2015 for 20CR3 and Jan 1851 to Dec 2014 for 20CRv2c.
