W3FT212

The W3FT212 routine converts a northern hemisphere 1.0
            degree lat.,lon. 361 by 91 grid to a Lambert
            Conformal 185 by 129 AWIPS grib 212.

USAGE:  CALL W3FT212(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  - 185*129 REGIONAL - CONUS
               DOUBLE RESOLUTION
               (LAMBERT CONFORMAL). 23865 POINT GRID
               IS AWIPS GRID TYPE 212

   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 185*129 GRID ORIENTATION
       AFTER INTERPOLATION. YOU MAY USE W3FC08 TO DO THIS.
