using oacres:plz help

[Isilda da Cunha Menezes]

Hello!
You need create a file of station data as it indicates in the book given
in by Grads, using the fortran program that there is described. Then you
have to create one linear and unitary matrix that cover in latitude and
longitude all of the locations of the stations that you dispose and create
an ctl identical to what was  described in the book, for grid data. You
have also create a ctl for the stations data as it indicates the same book
and don't forgetting  run the command stnmap -1 in DOS to create the file
map. Then, in the gs you should open theses ctls, with the ctl of the
stations in second place and not to forget of writing dfile 2 later,
finally it uses the command d oacres(variable of the
grid(matrices),variable of the stations). It can obtain the levels and
times that you want before writing this finish command.

I hope this helps.
