Hydrol_split for ae_ns

Description

The split of input variables to the soil tiles is performed in hydrol_split_soil and has been simplified in r3402 (see ticket #191).

The case of bare soil evaporation (evapnu splitted to ae_ns) has been left out as it was not working as expected.

It would required further work now that the nobio has been excluded from the soiltile 1 (Ticket #222).

  • Resolution set to fixed
  • Status changed from new to closed

In revisions [5805] and [5806], the "split" of the (grid-cell) evapnu into the (soitle-scale) ae_ns is now done like for the other variables (in hydrol_split_soil). To ensure conservation, this requires to always keep consistentcy between three variables: evap_bare_lim_ns, evap_bare_lim, and vbeta4. This involved changes in diffuco.

These changes allowed to solve problems of negative total soil moisture reported by Aude Valade in numerical experiments without rainfall.

They probaly solve the pbs reported by Dan Zhu in ticket #438.
