CRUNCEP download url changed to https

The thredds website just changed its url syntax from http to https. That results in a download error in PEcAn for CRUNCEP data.

I tried a run at US-Wkg for 1990-2009 and got these errors with at this point in the download:

> PEcAn.utils::logger.info(dap_file)

syntax error, unexpected WORD_STRING, expecting WORD_WORD

That url doesn't exist, but if you truncate it to https://thredds.daac.ornl.gov/thredds/catalog.html, you reach a notice that says "NOTICE: SDAT and THREDDS website and web service URLs will change to HTTPS on 2017-06-12. Read more."

I guess the download.CRUNCEP function needs to be updated.

Thanks for pointing this out @annethomas Will get a fix soon.

Uh oh, this looks more complicated. Looks like MSTIMIP CRUNCEP has moved to NASA, THREDDS catalog is empty! https://thredds.daac.ornl.gov/thredds/catalog/ornldaac/1220/catalog.html @jsimkins2 Know good contacts here?

[jsimkins2]

Just sent some emails out, hopefully we get a response soon!

[jsimkins2]

Contacted Deborah Huntzinger at NAU, she said they're looking into it now

[jsimkins2]

Problem Solved. There was a glitch in the system. The new THREDDS server is up and running. I'll add the changes to my current PR

[ankurdesai]

Great. Glad it was simple.
