20th Century Reanalysis Daily Composites

We have transitioned the data files from netCDF3 to netCDF4-classic format (transition date: Aug 14th).

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 1871 to Dec 2012 for 20CRV2 and Jan 1851 to Dec 2014 for 20CRv2c. See opportunities for improvement doc when using 1851-1860 for V2c.
