Modules
module	orog_utils
	Module containing utilites used by the orog program.

Functions/Subroutines
subroutine, public	orog_utils::find_nearest_pole_points (i_north_pole, j_north_pole, i_south_pole, j_south_pole, im, jm, is_north_pole, is_south_pole)
	Find the point on the model grid tile closest to the north and south pole.
subroutine, public	orog_utils::find_poles (geolat, nx, ny, i_north_pole, j_north_pole, i_south_pole, j_south_pole)
	Find the point on the model grid tile closest to the north and south pole.
subroutine, public	orog_utils::get_index (imn, jmn, npts, lono, lato, delxn, jst, jen, ilist, numx)
	Determine the location of a cubed-sphere point within the high-resolution orography data.
real function, public	orog_utils::get_lat_angle (dy)
	Convert the 'y' direction distance of a cubed-sphere grid point to the corresponding distance in latitude.
real function, public	orog_utils::get_lon_angle (dx, lat_in)
	Convert the 'x' direction distance of a cubed-sphere grid point to the corresponding distance in longitude.
real function, public	orog_utils::get_xnsum (lon1, lat1, lon2, lat2, imn, jmn, glat, zavg, zslm, delxn)
	Count the number of high-resolution orography points that are higher than the model grid box average orography height.
subroutine, public	orog_utils::get_xnsum2 (lon1, lat1, lon2, lat2, imn, jmn, glat, zavg, delxn, xnsum1, xnsum2, hc)
	Count the number of high-resolution orography points that are higher than a critical value inside a model grid box (or a portion of a model grid box).
subroutine, public	orog_utils::get_xnsum3 (lon1, lat1, lon2, lat2, imn, jmn, glat, zavg, delxn, xnsum1, xnsum2, hc)
	Count the number of high-resolution orography points that are higher than a critical value inside a model grid box (or a portion of a model grid box).
logical function, public	orog_utils::inside_a_polygon (lon1, lat1, npts, lon2, lat2)
	Check if a point is inside a polygon.
subroutine, public	orog_utils::latlon2xyz (siz, lon, lat, x, y, z)
	Convert from latitude and longitude to x,y,z coordinates.
subroutine, public	orog_utils::minmax (im, jm, a, title, imax, jmax)
	Print out the maximum and minimum values of an array and optionally pass back the i/j location of the maximum.
subroutine, public	orog_utils::remove_isolated_pts (im, jm, slm, oro, var, var4, oa, ol)
	Remove isolated model points.
real function	orog_utils::spherical_angle (v1, v2, v3)

real function, public	orog_utils::timef ()
	Get the date/time from the system clock.
subroutine, public	orog_utils::transpose_mask (imn, jmn, mask)
	Transpose the global landmask by flipping the poles and moving the starting longitude to Greenwich.
subroutine, public	orog_utils::transpose_orog (imn, jmn, glob)
	Transpose the global orography data by flipping the poles and moving the starting longitude to Greenwich.
