Energy was suggested as a potential point of interest for intercomparison. With a number of contributors, we have compiled 10 reanalyses or their model ensembles.
Global Intercomparison powerpoint and spreadsheet (this are very preliminary and may be updated in time, do not present without checking status with Mike B first)
In 8/2/18 update. Mike presented the global atmosphere balance of the various reanalyses.
8/8/18 follow up. Mike and Hans worked out an issue with the presentation of ERA20CM. The software being used to read the ensemble members used the first member's scale factor and offset, but did not recognize that each member had its own scale factor and offset. This has been corrected and ERA20CM is now properly presented in the current file. The analysis can be found here.
