ECA&D contain some serious errors:

1. look at the spatial distribution and location of the stations used

http://eca.knmi.nl/download/ensembles/data/ensembles_tg_stations_v12.0.txt
http://eca.knmi.nl/download/ensembles/data/ensembles_tn_stations_v12.0.txt
http://eca.knmi.nl/download/ensembles/data/ensembles_tx_stations_v12.0.txt
http://eca.knmi.nl/download/ensembles/data/ensembles_rr_stations_v12.0.txt

2. calculate annual averages and check if they match your
expectations. They did not match my expectations (and those of my
group) so we decided to ditch ECA&D.

If possible, use a datasource different from ECA&D.
