hi roland: 

it looks like a bug in the DAS:

    NC_GLOBAL {
        String sensor heights (agl) "Winds               3.4 m

I think 

  sensor heights (agl)

should be a single token or something. 

What is the server? It doesnt look like a TDS. Is it hyrax ?

The underlying file might be a new version of netcdf that allows blanks in the 
attribute names, and the server doesnt yet know how to deal.
