subroutine, public sflx_snippet::frh2o

(

)

Calculate the liquid water (slc) for a given total moisture content and soil temperature.

Used here to update slc when DA update to stc crosses freezing. Note this is an approximation, since in sflx.F (noah) the change in slc estimated by this routine is often clipped, depending on the net energy input to the soil layer. Also, this routine is being called using stc, but in sflx.F it is called using the soil temp at the midpoint of the layer. However, testing shows the affects of these approximations is small (O(0.001 m3/m3)).

Parameters

[in]	tkelv	Soil temperature in K
[in]	smc	Soil moisture
[in]	sh2o	Input liquid soil moisture
[in]	smcmax	Max soil moisture
[in]	bexp	B exponent
[in]	psis	Saturated matric potential
[out]	liqwat	Output liquid soil moisture
