Web-based Reanalysis Intercomparison Tool: Vertical Profiles of Reanalysis Datasets

Select a date, location and a dataset. You can choose from vertical profiles, vertical transects and height by time plots. For profiles, you will also get a table of the atmospheric variables for that date or range of dates. Please send feedback! The page is beta and there are some caveats.

Additional Notes

  • Reanalysis: 20CR and R1 have different pressure levels available. The R1 is on a 2.5 grid while the 20CR is on a ~2x~2 grid.
