The 1.5 DBN model used to assess the data quality of individual temperature and conductivity sensors in Sullivans Cove, Hobart at 1 m and 10 m. The causes of sensor degradation in this model were the time since the sensor was calibrated in node A and the time since the sensor was cleaned in node B. The latent states used to infer the data quality in node C were defined by the IOC flagging standard. The observed evidence of data quality was the seasonal difference in node D, the gradient in node E, the difference between the sensor and hydrodynamic model in node F (only for sensors at 1 m) and in node G the difference between equivalent sensors at alternate depths.
