The data are archived in the ECMWF data archive (MARS) and the data have been copied to the Climate Data Store (CDS). The data should be downloaded using the CDS catalogue or the CDS API, which can obtain data from the CDS copy or from MARS (Member State users can access the data using MARS directly, in the usual manner). Documentation on how to use the CDS API to download ERA5-Land data can be found here. The installation and downloading steps are similar to those of ERA5.
A couple of downloading examples to extract the data from MARS or from the CDS using the CDS API are given below:

The data in the native grid can be accessed from MARS using the keywords class="l5" and expver=0001. Subdivisions of the data are labelled using the keywords 'stream' and 'type'. The keyword 'levtype' should be set to 'sfc' for all the fields in ERA5-Land.
