Documentation of the ERA5 archive at GFI

GFI is building up an archive of ERA5 reanalysis data on the local linux system cyclone.hpc.uib.no. ERA5 supersedes the ERA-Interim reanalysis data, which ended in August 2019. More information about the ERA5 reanalysis data set is available at ECMWF's ERA5 websites.

The ERA5 data files are available in netCDF format at

/Data/gfi/share/era5

At GFI, we share the data format with the IAC at ETH Zürich, Switzerland; the LSD group at Karlsruhe Institute of Technology, Germany; and the Weizmann Institute of Science, Rehovot, Israel. The data are organised as follows

ml/        3-hourly data on a regular 0.5 deg latitude-longitude grid
pl/         pressure level data at different resolutions (not yet retrieved)

Data files are contained in subdirectories for each year and month:

ml/YYYY/MM/[B|H|P|Z]YYYYMMDD_HH

The data files contain the following variables:

File name P<yyyy><mm>

_< hh> Z<yyyy><mm>
