Daily Mean Composites: Includes Derived Variables

The NCEP/NCAR Reanalysis is delayed at the source. We don't have an estimated date it will be updated at this time.
Plot daily composites (averages) of the mean or anomalies (mean - total mean) of variables from the NCEP/NCAR Reanalysis and other datasets. Total means are based on 1981-2010. Data is available from Jan 1948 to Apr 15, 2025 for most variables.
Enjoy!
