<p class="MsoNormal">No my issue was never resolved. I contacted Dave Stepaniak about this and he speculates that it is possible, however, trying to add my RDA username/passwd to the NCL Opendap call is another issue. I can set my cookies using wget to remotely
access an RDA dataset but doing this in NCL is proving problematic. I have decided to run a NCL script on geyser to access the data on glade ans sftp it back to me. However, I am running into another issue. If I transfer the data using NETCDF3 it works
OK. However when I use the setfileoption to netcdf4 the file fills with missing values on my local system(although it is Ok on glade). I am assuming that it is some issue with sftp.
