[gradsusr] Impending shutdown of GDS server nomads.ncdc.noaa.gov/dods

Thu Jan 12 10:48:25 EST 2017

This is to inform GrADS Users of https://nomads.ncdc.noaa.gov/dods/ ~

Regretfully,
This service is scheduled to be taken offline by the* end of February* 2017.

The two primary reasons being the US Government HTTPS mandate
   (Jan 2017) rendering the server largely useless.
   This was essentially"Death from above".

And 2, the changing server enviornments are demand the application
   be run under a recent version of Tomcat 7+.  Preferably delivered by a
.war file
   that can be dropped into the container..

If these two issues could be addressed, we may be
   able to resurrect this service.

This message has *no direct affiliation *with:
http://nomads.*ncep*.noaa.gov/dods-alt
The NCEP component will remain up,
but is also in some degree of danger, I cannot address further.

NCDC-NOMADS THREDDS services can be used in some cases
to compensate opendap functionality for NCEP model datasets
but generally will not work via. a local GrADS client via. sdfopen.

Some more detail:

GDS generates links (hrefs) in the form of HTTP://hostname:443/URI instead
of HTTPS://hostname/URI

Even so... Trying sdfopen fails :

An alternate form, also "no dice":
