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]	ALAMB	101*81 regional - central us mard double res. (lambert conformal). 8181 point grid is awips grid type 209

Note

• 1. W1 and w2 are used to store sets of constants which are reusable for repeated calls to the subroutine. 11 other array are saved and reused on the next call.
• 2. Wind components are not rotated to the 101*81 grid orientation after interpolation. You may use w3fc08() to do this.
