W3FT209

The W3FT209 routine converts a northern hemisphere 1.0 
            degree lat.,lon. 361 by 91 grid to a Lambert Conformal
            101 by 81 awips grib 209.

USAGE:  CALL W3FT209(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  - 101*81 REGIONAL - CENTRAL US MARD DOUBLE RES.
               (LAMBERT CONFORMAL). 8181 POINT GRID IS AWIPSi
               GRID TYPE 209

   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 101*81 GRID ORIENTATION
       AFTER INTERPOLATION. YOU MAY USE W3FC08 TO DO THIS.
