Greeting, What is the estimated uncertainty value in Temperature, relative humidity, U and V winds of ERA-Interim data?

  • $\begingroup$ Do they make such estimations? $\endgroup$

There is no traceable uncertainty associated with each datum in the ERA-Interim reanalysis.

However, in ERA-5 there is an ensemble. This multiplies the data volume, but it means you can use the spread between the ensemble members to get an estimate. See ERA-5 page. ECMWF want us to use ERA-5 now anyway.

  • $\begingroup$ That page doesn't exist anymore, but there's this: confluence.ecmwf.int/display/CKB/… . There's a good paragraph there that describes the uncertainty that could be useful as a quote. $\endgroup$
