# This is currently a placeholder for a better example
from siphon.catalog import TDSCatalog
from siphon.http_util import session_manager

cat = TDSCatalog('http://thredds.ucar.edu/thredds/catalog.xml')
print(list(cat.catalog_refs))

['Forecast Model Data', 'Forecast Products and Analyses', 'Radar Data', 'Satellite Data', 'Text Products', 'Unidata case studies']
