Validation of the TMOR calibration

The fitted TMOR function was used to validate the suitability of the sensor for aviation use by following the process of comparison defined in the ICAO Manual of Runway Visual Range Observing and Reporting Practices (Doc 9328, AN/908). This procedure defines the selection and processing of the data from a sensor under test and the method of comparison with a calibrated transmissometer. This involves presenting the data as a form of box plot and checking the data does not fall outside certain accuracy limits. The following figure is an example plot of one sensor under test.
