1. time seems to correspond to NominalTime ? is it important to also 
identify actual time ? is granularity of one minute adequate?

2. "feet * 100" should be "100 feet"

3.  :_dataType = "station" should be  :cdm_datatype = "station" (i 
assume you got this from us? weve changed that recently)

4. Weve just published some recommended global attributes that connect 
to THREDDS at:
 
http://my.unidata.ucar.edu/content/software/netcdf-java/formats/DataDiscoveryAttConvention.html

some that are particularly useful are :

 summary : paragraph describing the dataset

 keywords : for digital library searching

 lat/lon bounding box:  geospatial_lat_max, geospatial_lat_min, 
geospatial_lon_max, geospatial_lon_min

 time range: time_coverage_start, time_coverage_end

 unique name : id, naming_authority

try using a \n, that is not a new line char, but the two characters "\" 
and "n". See the manual at
