(rlat[i],rlon[i]) is the lat/lon coordinate corresponding to the Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1. .IP y 12 An array containing the Y component of the Cartesian coordinates of the input data. (rlat[i],rlon[i]) is the lat/lon coordinate corresponding to the Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1. .IP z 12 An array containing the Z component of the Cartesian coordinates of the input data. (rlat[i],rlon[i]) is the lat/lon coordinate corresponding to the Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1. .IP rlat 12 An array containing the latitudes of the output coordinates, in degrees. .IP rlon 12 An array containing the longitudes of the output coordinates, in degrees. .SH USAGE c_csc2s is called to find the equivalent lat/lon coordinates to specified Cartesian coordinates on a unit sphere. The Cartesian coordinate (1.,0.,0.) is converted to lat/lon coordinate (0.,0.). Latitudes and longitudes are assumed to be in degrees. .SH RETURN VALUE c_csc2s does not return a value. .SH ACCESS To use c_csc2s, load the NCAR Graphics library ngmath. .SH SEE ALSO css_overview, c_cssgrid, c_css2c. .sp Complete documentation for Cssgrid is available at URL .br http://ngwww.ucar.edu/ngdoc/ng/ngmath/cssgrid/csshome.html .SH COPYRIGHT Copyright (C) 2000 .br University Corporation for Atmospheric Research .br The use of this Software is governed by a License Agreement.
