Ensemble timeseries¶
For the CLIPC project, a multimodel ensemble was composed and stored in a single NetCDF file with an extra dimension named "member". The data can be found here: https://climate4impact.eu/impactportal/data/catalogbrowser.jsp?catalog=http://opendap.knmi.nl/knmi/thredds/catalog/CLIPC/knmi/RCM/EUR-44/BC/tas/catalog.xml?
A OpenDAP URL to such a file is http://opendap.knmi.nl/knmi/thredds/dodsC/CLIPC/knmi/RCM/EUR-44/BC/tas/hd17_icclim-4-2-3_KNMI_ens-multiModel_historical_r1i1p1_SMHI-RCA4_v1_EUR-44_SMHI-DBS43_EOBS10_bcref-1981-2010_yr_19700101-20051231.nc
