<div>Hi Mary,</div>
<div>Thank you for your answer. Indeed, the issue arises when I use “ncl_convert2nc” (see below). An example of the .grb files I’m dealing with is at:</div>
<div><a href="ftp://hydro1.sci.gsfc.nasa.gov/data/s4pa/NLDAS/NLDAS_VIC0125_H.002/2000/001/NLDAS_VIC0125_H.A20000101.0000.002.grb">ftp://hydro1.sci.gsfc.nasa.gov/data/s4pa/NLDAS/NLDAS_VIC0125_H.002/2000/001/NLDAS_VIC0125_H.A20000101.0000.002.grb</a> </div>
<div>I’ve also tried “ng4ex xy01n -clean” but the problem I face there seems to be that X11 is not installed on my machine (see below). Is X11 required to be able to use ncl_convert2nc? This is almost the only tool I need for now in NCL. As I’m converting
multiple years of hourly files, this tool comes in extremely handy. I had used it with NCL 6.2.0 on another machine and it worked fine with these .grb files. Is there any other example NCL script that I can try to run that doesn’t use X11?</div>
<div>Your thoughts are much appreciated!</div>
<div>Thank you,</div>
