Function/Subroutine Documentation

calc_density()

subroutine, public bulk_snow_module::calc_density	(	integer, intent(in)	lensfc,
		integer, dimension(lensfc), intent(in)	landmask,
		real, dimension(lensfc), intent(in)	swe,
		real, dimension(lensfc), intent(in)	snd,
		integer, intent(in)	rank,
		real, dimension(lensfc), intent(out)	density
	)

This subroutine calculates snow density from forecast fields.

density = SWE/SND where snow present. = average from snow forecasts over land, where snow not present

Parameters

[in]	lensfc	Number of sfc grid cells
[in]	rank	Processor rank
[in]	landmask	Mask for land increments
[in]	swe	Snow Water Equivalent
[in]	snd	Snow Depth
[out]	density	Snow density [-]
