Currently, the data can only be downloaded on a regular latitude/longitude grid of 0.1°x0.1° via the CDS catalogue. ECMWF member states with access to the ECMWF Meteorological Archival and Retrieval System (MARS) can also retrieve the data in the native grid.

NOTE: Please, note that since 1st Jan 2020 the new ECMWF Meteorological Interpolation and Regridding interpolation package (MIR) has been used to interpolate the atmospheric forcing of ERA5 into the ERA5-Land grid. While this change will be unnoticeable for the overwhelming majority of users, locally and under very limited conditions (some areas with high orography, some coastal points) some fields may suffer of a very small discontinuity this day. |

For the sake of completeness, most of the forcing fields used to run ERA5-Land are included in the catalogue. Note, however, that these fields have purely been interpolated to the ERA5-Land grid and they are not obtained by running the land surface model (i.e., a purely linear interpolation based on a triangular mesh). They are included in Table 1 and Table 2 below under the column "Used as forcing field".
