Subdaily 20thC Reanalysis Data Composites

Plot maps or composites of variables from the 20th Century Reanalysis dataset. Data is available from Jan 1836 to 2015 for (20CRV3) and from Jan 1851 to 2014 for (20CRV2c).

Variables Analysis level? Version? 20CRV3 20CRV2c
Enter Year, Month and Day and Hour(0,6,12,18z) for composites
For example, 1999 1 1 18 (Don't type in the z). To subtract one set of days from another, use a minus sign (-) before the years of the days that are to be subtracted. Default is last available date for variable.
