SUBROUTINE: W3FT205 CONVERT (361,91) GRID TO (45,39) N.

HEMI. GRID AUTHOR: JONES,R.E. ORG: W342 DATE: 93-10-19

ABSTRACT: CONVERT 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 60 DEG. W. POLE POINT IS AT (I,J) = (27,57). NEW MAP IS AWIPS MAP 205.
