Update NCEP TDS data access URLs #82
Conversation
|
So I wouldn't describe the NCDC links as "new". NCDC (and a few other centers) were renamed to NCEI. I'll also add that the TDS at the NCDC URLs is a few revisions behind that available at NCEI. Having said that, the most important aspect is that the NCDC links actually work. |

A good start. Can you fix up the rest of the places where you needed to change the URL that included "grid" to properly use Siphon to read the catalog? That's really best practice anyway and makes use more insulated from changes on the server.

This line isn't even used, and really doesn't make sense for archived data.

Let's eliminate the hard-coding of the grid vs. not (which is a thredds server issue) by actually using the catalog. So let's update to something like:
cat = TDSCatalog('https://www.ncdc.noaa.gov/thredds/catalog/namanl/201604/20160416/catalog.xml')
ncss = cat.datasets['namanl_218_20160416_1800_000.grb'].subset()| "\n", | ||
| "And we will use a python package called Siphon to read this data through the NetCDFSubset (NetCDFServer) link.\n", | ||
| "\n", | ||
| "https://www.ncei.noaa.gov/thredds/ncss/grid/narr-a-files/199303/19930313/narr-a_221_19930313_0000_000.grb/dataset.html" |

Let's just kill this link.

Replace the old
ncei.noaa.govTDS URLs I found with their newncdc.noaa.govcounterparts as described in (and closes) #81. Not sure if this is the preferred workflow forpython-trainingor if anything else needs to change to squeeze this in. Let me know!
