20th Century Reanalysis V2 Monthly/Seasonal Composites: Google Earth

Plot seasonal composites (averages) of the mean or anomalies (mean - total mean) of variables from the 20th Century Reanalysis reanalysis. Output is a KML/KMZ file and a link to the Google Earth Browser Interface. 20th century reanalysis data is available from Jan 1871 to Dec 2012.

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.
