Livneh Monthly/Seasonal Climate Composites

Plot seasonal composites (averages) of the mean or anomalies (mean - total mean) of Livneh variables. Data is available from Jan 1915 to Dec 2011.

The resolution of the LIVNEH dataset on this page is 4km. They make available a higher resolution version you can get at their website.
Note for states, choose "individual states" for map region and then the state.

? Which variable?
? 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.
