Time Section Plots Using NCEP Daily Data

This page will be discontinued in the future. The current page can be found at http://www.esrl.noaa.gov//map/time_plot/. This page is being provided as a convenience to match the older plots.

Data Availability
  • Operational data are available from Jan 1, 1979 through 09/29/2020
  • Reanalysis data are available from Jan 1, 1948 through 09/27/2020
  • Outgoing Longwave Radiation data are available from June 1, 1974 through Dec 31 2019 .

(Default plot is Time-Longitude along the Equator with no area averaging)

Additional Notes

  • Operational: All mean, anomaly, and climatology plots can be created. Pressure levels available: 1000, 850, 700, 500, 400, 300, 250, 200, 150, 100, 70, 50.
  • Reanalysis: No climatology for surface relative humidity, therefore no climatology or anomaly plots. All pressure levels plus surface are available.
