Land Surface Model (LSM) output:

We ask for a NetCdf file which contains standard ALMA (version 3 of the ALMA convention for model output) output, and some additional ones, in red in the following table.

The sign convention for the output should be taken from the Traditional definition and not the Mathematical definition.

All data should be given as 10-min averages.
