Member Function/Subroutine Documentation

subroutine utilities::check_cnwat	(	real(esmf_kind_r8), dimension(i_input,j_input), intent(inout)	cnwat,
		integer, intent(in)	i_input,
		integer, intent(in)	j_input
	)

When using GEFS data, some points on the target grid have unreasonable canpy moisture content, so zero out any locations with unrealistic canopy moisture values (>0.5).

Parameters

cnwat	[input] 2-dimensional canopy moisture content
i_input	[in] i-dimension of input grid
j_input	[in] j-dimension of input grid

subroutine utilities::check_soilt	(	real(esmf_kind_r8), dimension(i_input,j_input,lsoil_input), intent(inout)	soilt,
		integer(esmf_kind_i4), dimension(i_input,j_input), intent(in)	landmask,
		real(esmf_kind_r8), dimension(i_input,j_input), intent(in)	skint,
		real, intent(in)	ICET_DEFAULT,
		integer, intent(in)	i_input,
		integer, intent(in)	j_input,
		integer, intent(in)	lsoil_input
	)

Check for and replace certain values in soil temperature.

At open water points (landmask=0) use skin temperature as a filler value. At land points (landmask=1) with excessive soil temperature, replace soil temperature with skin temperature. In GEFSv12.0 data there are some erroneous missing values at land points which this corrects. At sea ice points (landmask=2), store a default ice column temperature because grib2 files do not have ice column temperature which FV3 expects at these points.

Parameters

soilt	[inout] 3-dimensional soil temperature arrray
landmask	[in] landmask of the input grid
skint	[in] 2-dimensional skin temperature array
ICET_DEFAULT	[in] Default temperature to apply at ice points
i_input	[in] i-dimension of input grid
j_input	[in] j-dimension of input grid
lsoil_input	[in] soil layers dimension of input grid

	)

Pressure to presure vertical interpolation for tracers with linear or lnP interpolation.

Input tracers on pres levels are interpolated to the target output pressure levels. The matching levels of input and output will keep the same. Extrapolation is also allowed but needs caution. The routine is mostly for GFSV16 combined grib2 input when spfh has missing levels in low and mid troposphere from U/T/HGT/DZDT.

Parameters

[in]	ppin	1d input pres levs
[in]	xxin	1d input tracer
[in]	npin	number of input levs
[in]	ppout	1d target pres levs
[out]	xxout	1d interpolated tracer
[in]	npout	number of target levs
[in]	linlog	interp method.1:linear;not 1:log;neg:extrp allowed
[in]	xmsg	fill values of missing levels (-999.0)
[out]	ier	error status. non 0: failed interpolation
