Only 2-3 core fields are stored in the database: the name and latitude/longitude of the station. Any other information is taken directly from the dataproviders. This should make it easy to verify the mapping between the different data provders.
RSS feeds and webservices are provided to retrieve information from the SSC.
Data providers are encouraged to verify and/or add their own stations
