in evaluating their adequacy with respect to channel accuracy and the potential for acceptable data recovery. The suitability of the specific type of sensor for use in the environmental conditions at the site is evaluated. To this end, the range of wind, temperature, and moisture conditions and the ability of the sensors to withstand harsh environments (such as extreme cold/hot, high winds, corrosion, blowing sand or dust, salt, air pollutants, birds or other wildlife, and insects) are considered. If the instrumentation is new or differs from what is typically used in a meteorological monitoring program (such as SOnic Detection and Ranging (SODAR) measurements), then the application should justify doing so including, but not limited to, how the measurement technology is appropriate and how the resulting data will be used (e.g., input to dispersion models and its compatibility with the model algorithms based on how a particular model was developed). In such cases, meteorological instrumentation and dispersion modeling experts may need to be consulted. . c. Recording of Meteorological Sensor Output Information regarding the methods of recording (such as digital or analog; instantaneous or average; engineering units or raw voltages) and the recording equipment, including performance specifications and location of this equipment, is evaluated. Manufacturers' specifications and the applicant’s operating experience with the recorders are considered in evaluating their adequacy with respect to system accuracy and the potential for acceptable data recovery. The controlled environmental conditions in which the sensor processors and recorders are kept (such as the instrument shelter or control room) are reviewed for adequacy in accordance with the manufacturers' specifications. The ability to obtain a direct readout from the recorders in situ during routine inspection of systems is checked to ensure that the inspector will be able to relate the recorder 2.3.3-12 Draft
