W3FT203
The W3FT203 routine converts a northern hemisphere 1.0 degree
lat.,lon. 361 by 91 grid to a polar stereographic
45 by 39 grid. The polar stereographic map projection is
true at 60 deg. N., The mesh length is 190.5 km. and the
oriention is 150 deg. W.
USAGE: CALL W3FT203(ALOLA,APOLA,INTERP)
Input arguments:
ALOLA - 361*91 GRID 1.0 LAT,LON GRID N. HEMISPHERE
32851 POINT GRID IS O.N. 84 TYPE ?? OR ?? HEX
INTERP - 1 LINEAR INTERPOLATION , NE.1 BIQUADRATIC
Output arguments:
APOLA - 45*39 GRID OF NORTHERN HEMISPHERE.
1755 POINT GRID IS AWIPS GRID TYPE 203
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.
2. WIND COMPONENTS ARE NOT ROTATED TO THE 45*39 GRID ORIENTATION
AFTER INTERPOLATION. YOU MAY USE W3FC08 TO DO THIS.
