The ERA-15 Re-analysis project was devised in response to wishes expressed by many users for a data set generated by a modern, consistent, and invariant data assimilation system. The ERA-15 project produced a long time-series (January 1979 - February 1994) of consistent meteorological analyses using a single version of the ECMWF model. This dataset contains surface orography data. These data are available in gaussian N80 gridded, lat-long (2.5 degree) gridded and spectral form, from the initialised and uninitialised datasets (N.B. initialised spectral is missing at the moment). Note that the grid-point orography files change with date. This does not affect the ERA period but if you use Operational data for later dates you will need to use the different orography files from our ecmwf-op directory. The spectral orography file spor90010100 contains just the orography data (surface geopotential). The other files contain the constant fields: Geopotential (at the surface, orography) Standard deviation of orography Anisotropy of subgrid scale orography Angle of subgrid scale orography Slope of subgrid scale orography Land/Sea mask gpor79010100 contains the gaussian gridded data llor80010100 contains the 2.5 degree gridded data European Centre for Medium-Range Weather Forecasts (ECMWF) author unknown author NCAS British Atmospheric Data Centre (NCAS BADC) custodian +44(0)1235 446432 British Atmospheric Data Centre STFC Rutherford Appleton Laboratory Harwell Oxford OX11 0QX UK badc@rl.ac.uk custodian NCAS British Atmospheric Data Centre (NCAS BADC) distributor +44(0)1235 446432 British Atmospheric Data Centre STFC Rutherford Appleton Laboratory Harwell Oxford OX11 0QX UK badc@rl.ac.uk distributor European Centre for Medium-Range Weather Forecasts (ECMWF) principal_investigator unknown principalInvestigator NCAS British Atmospheric Data Centre (NCAS BADC) point_of_contact +44(0)1235 446432 British Atmospheric Data Centre STFC Rutherford Appleton Laboratory Harwell Oxford OX11 0QX UK badc@rl.ac.uk pointofContact NCAS British Atmospheric Data Centre (NCAS BADC) publisher +44(0)1235 446432 British Atmospheric Data Centre STFC Rutherford Appleton Laboratory Harwell Oxford OX11 0QX UK badc@rl.ac.uk publisher notPlanned dataset ECMWF ERA ERA 15 reanalysis surface orography atmospheric conditions theme GEMET - INSPIRE themes, version 1.0 2008-06-01 publication otherRestrictions Access to these data is available to any registered CEDA user.
