[ncl-talk] CFSR from OpenDAP

[Rick Brownrigg]

Hi Carl,

Try "http:" rather than "https:" -- it worked for me.  In the case of
"https:", an strace of NCL revealed it was looking only in the local file
system for the file, and there was no network activity.  I don't know if
that is a bug or intentional behavior.
