NAME
       CSSGRID - tension spline interpolation on a sphere.


SYNOPSIS
       CALL CSSGRID (N, RLAT, RLON, F, NI, NJ, PLAT, PLON, FF, IWK, RWK, IER)


DESCRIPTION
       N           (integer,input) The number of input data points (N > 2).

       RLAT        (real,  input)  An array containing the latitudes of the input data, expressed
                   in degrees.  The first three points must not be collinear  (lie  on  a  common
                   great circle).

       RLON        (real,  input) An array containing the longitudes of the input data, expressed
                   in degrees.

       F           (real, input) An array containing data values. F(I) is a functional  value  at
                   (RLAT(I),RLON(I)) for I = 1 to N.

       NI          (integer, input) The number of rows in the uniform output grid. NI can be 1.

       NJ          (integer,  input)  The number of columns in the uniform output grid. NJ can be
                   1.

       PLAT        (real, intput) An array of length NI containing the latitudes the output  grid
                   lines.  The values in PLAT should be in degrees.

       PLON        (real, intput) An array of length NJ containing the longitudes the output grid
                   lines.  The value in PLON should be in degrees.

       FF          (real, output) An NI by NJ array containing the desired  interpolated  values.
                   FF(I,J)  is  the interpolated value at the coordinate specified by PLAT(I) and
                   PLON(J) for I = 1 to NI and J = 1 to NJ.

       IWK         (integer, input) An integer workspace of length 27*N.

       RWK         (double precision, input) A work array dimensioned for 13*N.   Note  that  RWK
                   must be typed DOUBLE PRECISION.

       IER         (integer,  output)  An  error  return value.  If IER is returned as 0, then no
                   errors were detected. If IER is non-zero, then  refer  to  the  man  page  for
                   cssgrid_errors for details.


USAGE
       CSSGRID  is called to find an interpolating tension spline for data randomly positioned on
       a sphere.


ACCESS
       To use CSSGRID, load the NCAR Graphics library ngmath.
