Detailed Description

Process atmospheric fields.

Horizontally interpolate from input to target FV3 grid using ESMF regridding. Adjust surface pressure according to terrain differences between input and target grid. Vertically interpolate to target FV3 grid vertical levels. Processing based on the spectral GFS version of CHGRES.

For variables "b4adj" indicates fields on the target grid before vertical adjustment. "target" indicates data on target grid. "input" indicates data on input grid. "_s" indicates fields on the 'south' edge of the grid box. "_w" indicate fields on the 'west' edge of the grid box. Otherwise, fields are at the center of the grid box.

Search for a surrounding real interval.

This subprogram searches monotonic sequences of real numbers for intervals that surround a given search set of real numbers. The sequences may be monotonic in either direction; the real numbers may be single or double precision; the input sequences and sets and the output locations may be arbitrarily dimensioned.

If the array z1 is dimensioned (im,km1), then the skip numbers are ixz1=1 and kxz1=im; if it is dimensioned (km1,im), then the skip numbers are ixz1=km1 and kxz1=1; if it is dimensioned (im,jm,km1), then the skip numbers are ixz1=1 and kxz1=im*jm; etcetera. Similar examples apply to the skip numbers for z2 and l2.

Returned values of 0 or km1 indicate that the given search value is outside the range of the sequence.

If a search value is identical to one of the sequence values then the location returned points to the identical value. If the sequence is not strictly monotonic and a search value is identical to more than one of the sequence values, then the location returned may point to any of the identical values.

to be exact, for each i from 1 to im and for each k from 1 to km2, z=z2(1+(i-1)*ixz2+(k-1)*kxz2) is the search value and l=l2(1+(i-1)*ixl2+(k-1)*kxl2) is the location returned. if l=0, then z is less than the start point z1(1+(i-1)*ixz1) for ascending sequences (or greater than for descending sequences). if l=km1, then z is greater than or equal to the end point z1(1+(i-1)*ixz1+(km1-1)*kxz1) for ascending sequences (or less than or equal to for descending sequences). otherwise z is between the values z1(1+(i-1)*ixz1+(l-1)*kxz1) and z1(1+(i-1)*ixz1+(l-0)*kxz1) and may equal the former.

Parameters

[in]	im	integer number of sequences to search
[in]	km1	integer number of points in each sequence
[in]	ixz1	integer sequence skip number for z1
[in]	kxz1	integer point skip number for z1

[in]	kxz2	integer point skip number for z2

[in]	kxl2	integer point skip number for l2
[out]	l2	integer (1+(im-1)ixl2+(km2-1)kxl2) interval locations having values from 0 to km1 (z2 will be between z1(l2) and z1(l2+1))

Cubically interpolate in one dimension.

Interpolate field(s) in one dimension along the column(s). The interpolation is cubic lagrangian with a monotonic constraint in the center of the domain. In the outer intervals it is linear. Outside the domain, fields are held constant.

Vertically interpolate upper-air fields.

Vertically interpolate upper-air fields. Wind, temperature, humidity and other tracers are interpolated. The interpolation is cubic lagrangian in log pressure with a monotonic constraint in the center of the domain. In the outer intervals it is linear in log pressure. Outside the domain, fields are generally held constant, except for temperature and humidity below the input domain, where the temperature lapse rate is held fixed at -6.5 k/km and the relative humidity is held constant. This routine expects fields ordered from bottom to top of atmosphere.
