Writing to GrADS using Fortran

[Eduardo Blanchard]

Hello

 I am trying to write two different time series into a .grd file so I can
view them and for example do a scatter plot of the two time series in Grads

within the Fortran program, I do:

open(14,file='scatter.grd',form='unformatted',access='direct',recl=4*109)
write(14,rec=1)(IE(itime),itime=1,109)
write(14,rec=2)(data1(3,it),it=392,500)
close(14)

but in Grads this just opens two time series, length 54 that take
alternating values from one of my initial time vectors- in this case,
IE(itime)

My ctl file is:
DSET scatter.grd
TITLE   HGT
UNDEF   -99
TDEF 109 LINEAR 1aug90 1mo
XDEF 1 LINEAR 1 1
YDEF 1 LINEAR 1 1
ZDEF 1 LINEAR 1 1

VARS 2
f1 1 99 HT data
f2 1 99 HT data
ENDVARS

Any help is very much appreciated
