Please check my web site:

There is a utility xy2grads, which should be able to solve your problem

-----------------------------------

xy2grads ver. 0.3

convert 'x y var1 var2 .. varns' data from ascii to grads binary format
(REAL*4) (FLOAT).

copyright by Ben-Jei Tsuang, C.L. Chen, 2001, 2003, 2005

Usage: xy2grads -i ifile <-o ofile -m method -n nvar -h headers -s -u xw xe
dx ys yn dy -x missing>

Note:  Input data must be number. Each data should be seperated by

          either space, comma, tab, carrage return, + or -

Options 1) -i ifile

        2) -o ofile (default: out.bin)

        3) -h headers: number of headerlines to skip (default=1)

        4) -m 0: last one win

              1: mean (default)

              2: sum (e.g. for adding emission sources)

        5) -n nvar (default=1)

        6) -s: swap x,y order from (x y var1 var2 .. ) to (y x var1 var2
...)

        7) -u xw: leftmost coord. (default=0)

              xe: rightmost coord. (default=360)

              dx: x incr. (default=1)

              ys: southmost coord. (default=-90)

              yn: northmost coord. (default=90)

              dy: y incr. (default=1)

        8) -x missing: missing value (default=-9.99e33) [bjtsuang at bs1
