How to Check the Quality of Data from your Weather Station

• Individual station quality checking
• Equipment types in use

Philip has also set-up an e-mail reflector discussion list for CWOP quality checking. To join this list, send an e-mail to "wxqc-subscribe@lists.gladstonefamily.net" (without the quotes). This list will build up an archive that should contain a lot of pertinent information on the CWOP quality checking.

2. Quality Checking Summary Information

Current quality checking summaries for CWOP stations in the USA can be seen at QC Summary Messages.
