W3FT211

The W3FT211 routine converts a northern hemisphere 1.0
            degree lat.,lon. 361 by 91 grid to a Lambert Conformal
            93 by 65 AWIPS grib 211.

USAGE:  CALL W3FT211(ALOLA,ALAMB,INTERP)

   Input arguments:
      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.
      INTERP - 1 LINEAR INTERPOLATION , NE.1 BIQUADRATIC

   Output arguments:
      ALAMB  - 93*65 REGIONAL - CONUS
               (LAMBERT CONFORMAL). 6045 POINT GRID
               IS AWIPS GRID TYPE 211

   Input files:  NONE

   Output files: ERROR MESSAGE TO FORTRAN OUTPUT FILE

REMARKS:
   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 93*65 GRID ORIENTATION
      AFTER INTERPOLATION. YOU MAY USE W3FC08 TO DO THIS.
