cssgrid_Wrap

Uses tension splines to interpolate unstructured (randomly-spaced) data on a unit sphere to data values on a rectilinear grid (retains metadata).

Prototype

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"

	function cssgrid_Wrap (
		rlat [*] : numeric,  
		rlon [*] : numeric,  
		fval     : numeric,  
		plat [*] : numeric,  
		plon [*] : numeric   
	)

	return_val  :  float or double

Arguments

rlat
rlon

Arrays containing latitude and longitude values specifying locations of the input data. rlat and rlon are one-dimensional arrays of the same size, specified in degrees. The first three points must not lie on a common great circle.

fval

An array containing data values. fval can have any number of dimensions, but the final dimension must be the same size as that of rlat and rlon. This allows for multiple input datasets defined at the coordinates specified by rlat and rlon.

plat

An array containing the latitudes, in degrees, of the output grid lines.

plon

An array containing the longitudes, in degrees, of the output grid lines.

Description

This function is identical to cssgrid, except the return value will have metadata added based on fval. See the cssgrid page for full documentation and examples.
