una de las razones es que aunque grads lee archivos binarios, estos deben de tener una secuencia para que el grads los entienda, ademas en tu ctl marcas que la resolucion es de 1 grado y en el problema dices que estan a 2.5, haz bien el calculo.

one reason is that although grads read binary files, they must have a sequence so that the grads understand them, in addition to your ctl marks the resolution is 1 degree and the problem you say you are at 2.5, while the beam calculation.

      (phd0802 at pieas.edu.pk)
Hi! Users,

I am new user of GrADS and intend to plot NCEP GDAS dataset having 2.5 by
2.5 degree spetial and 12 hr temporal resolution. I have a file with
extension of bin. GrADS open the file taking the information from the data
descriptor file but don't display the variables properly showing some
awkward data interval and error nan nan infinity interval appears on the
command window.  i am attaching the data descriptor file herewith for your
review. Can any one help me to fix this problem?

Any help in this regard would be highly appreciated.

Best regards,
sabir sardar.
