w3ft213()

subroutine w3ft213	(	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 129 by 85 grid. The polar stereographic map projection is true at 60 deg. n. , The mesh length is 95.25 km. and the oriention is 105 deg. w. awips grid 213 national - conus - double resolution

Parameters

[in]	ALOLA	361*91 grid 1.0 deg. lat,lon grid n. hemi. 32851 point grid. 360 * 181 one degree grib grid 3 was flipped, greenwish added to right side and cut to 361 * 91.
[in]	INTERP	1 linear interpolation , ne.1 biquadratic
[out]	APOLA	129*85 grid of northern hemisphere. 10965 point grid is awips grid type 213

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 129*85 grid orientation after interpolation. You may use w3fc08() to do this.
