NARR Monthly/Seasonal Climate Composites

Plot seasonal composites (averages) of the NCEP monthly NARR Dataset (available from Jan 1979 to Apr 30, 2025 ).

? Which variable? Level?
? Beginning month of season: Ending month:
? Enter years for composites (from 1 to 20): 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.
