w3ft203()

subroutine w3ft203	(	real, dimension(361,91)	alola,
		real, dimension(npts)	apola,
			interp
	)

Convert a northern hemisphere 1.0 degree lat.,lon.

361 by 91 grid to a polar stereographic 45 by 39 grid. The polar stereographic map projection is true at 60 deg. n. , The mesh length is 190.5 km. and the oriention is 150 deg. w.

Parameters

[in]	ALOLA	361*91 grid 1.0 lat,lon grid n. hemisphere 32851 point grid is o.n. 84 type ?? or ?? hex
[in]	INTERP	1 linear interpolation , ne.1 biquadratic
[out]	APOLA	45*39 grid of northern hemisphere. 1755 point grid is awips grid type 203

Note

• 1. W1 and w2 are used to store sets of constants which are reusable for repeated calls to the subroutine.
• 2. Wind components are not rotated to the 45*39 grid orientation after interpolation. You may use w3fc08() to do this.
