6-Hourly NCEP/NCAR Reanalysis Data Composites

Plot maps or composites of variables from the NCEP/NCAR Reanalysis dataset. Data is available from Jan 1948 to Feb 18, 2013 for most variables

Some variables are not updated as frequently.

Variables

Analysis level?

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.

OR to Enter Year of last day of range

OR File with Dates Optional Plot Label replaces list of dates.
