[gradsusr] Problem with displaying opendap data of MODIS LST product MOD11A1.006

Mon Jul 20 06:30:38 EDT 2020

Hi All,

How can I display opendap data of the MOD11A1.006 product with the
following DATA URL:  http://opendap.cr.usgs.gov/opendap/hyrax/MOD11A1.006

There are a number of ncml files there.

I tried to use the sdfopen command line to open one of these files
(h12v12.ncml) but failed (below).

Any suggestion how to open these files in GRADS?

Kind regards,
