Auxiliary land invariant parameters are attached here below, already interpolated to a regular lat/lon grid of 0.1°x0.1°. Relevant information about how to use/interpret these fields are in chapter 8 of https://www.ecmwf.int/en/elibrary/18714-ifs-documentation-cy45r1-part-iv-physical-processes, and plots of these fields are in chapter 11.
Parameters described as "instantaneous" in Table 2 are valid at the specified time.
Note that in the tables below, "an" and "fc" is just a label used for convention to archive the data in MARS.
