The ERA-interim dataset comprise a large amount of reanalysis data covering years 1989-2008, created by the European Centre for Medium-Range Weather Forecasts.

A comprehensive description of the ERA-interim dataset can be found at

Data available at NoSerC

A part of the ERA-interim dataset is now available on the national storage facility NorStore. Please send an E-mail to Egil Støren at if you want access to these data.

Accumulated fields based on forecast:
These fields are based on accumulated fields from forecast runs at 00 and 12 UTC. For each variable, four fields are computed for each day. These are identified by "Hour of reference time of data" (RT) = 0 or 12, and "Time range one" (T1) = 6 or 12. The (RT,T1) combinations (0,6) (0,12) (12,6) and (12,12) corresponds to six hour accumulated values from UTC 00, 06, 12 and 18 respectively. Originally, the (0,12) and (12,12) fields contained 12 hour accumulated values from reference time, but the corresponding (0,6) and (12,6) fields have been substracted in order to obtain an homogenous time series with six hour accumulated values.
