Rainfall data from ERA and the ECMWF PROVOST ensembles. (in collaboration with ICTP)

A preprocessing of rainfall data from ERA and the ECMWF PROVOST ensembles (as included in the ECMWF CD-ROMs) has been performed, in order to allow an easy comparison between rainfall anomalies from ERA and the ensemble-mean in different years/seasons. From this dataset, a GRADS script produces colour plots of the two fields for specified periods (year, season, range of 10-day means) and regions (five longitude bands can be selected). An exemple of the output is attached.

It is planned to develop (by the end of the first year project) a web-based interface to simple verification tools like this one, (to be accessed from the PROMISE archive web page), and to apply them to other experimental datasets (e.g. PRISM).ã
