Workspace Method z_fieldFromHSE
Description
Force altitudes to fulfil hydrostatic equilibrium.
The method applies hydrostatic equilibrium. A mixture of "dry
air" and water vapour (if present as abs_species tag) is assumed.
That is, the air is assumed to be well mixed and its weight, apart
from the water vapour, is constant (molarmass_dry_air). In
addition, the effect of any particles (including liquid and ice
particles) is neglected.
The output is an update of z_field. This variable is expected to
contain approximative altitudes when calling the function. The
altitude matching p_hse is kept constant. Other input altitudes can
basically be arbitrary, but good estimates give quicker calculations.
The calculations are repeated until the change in altitude is below
z_hse_accuracy. An iterative process is needed as gravity varies
with altitude.
For 1D and 2D, the geographical position is taken from lat_true
and lon_true.
