m major obstructions, the influence should be minimal. ` Tower locations within five obstruction heights should be analyzed on a case-by-case basis. Meteorological Sensors The reviewer should evaluate meteorological sensors as follows: (1) Evaluate sensor type and performance specifications. (a) Consider manufacturers’ specifications, performance analyses, and operating experience for these sensors in evaluating their accuracy and potential for acceptable data recovery. (b) Use standardized evaluations and operational experience reports contained in research papers. Guidance for sensor evaluation is found in Regulatory Guide 1.23 and Atmospheric Science and Power Production (Randerson 1984). (2) Determine the suitability of the specific type of sensor for use in the environmental conditions expected to occur at the site, by considering the range of wind conditions and the ability of the sensors to withstand corrosion, blowing sand, salt, air pollutants, birds, and insects. (3) If the sensors are new and unique, consult a meteorological instrumentation expert (e.g., National Oceanic and Atmospheric Administration—Idaho National Engineering and Environmental Laboratory [NOAA–INEEL]) to complete the analysis. Recording of Meteorological Sensor Output The reviewer should evaluate the recording of the sensor output as follows: (1) Evaluate the methods of recording (e.g., digital or analog, instantaneous or average engineering units or raw voltages) and recording equipment, including performance specifications and location of the equipment. Consider manufacturers’ specifications and operating experience for the recorders when considering accuracy and the potential for acceptable data recovery. (2) Review the controlled environmental conditions in which the recorders are kept (instrument shelter or control room) for adequacy in accordance with the manufacturers’ specifications. Confirm the ability to obtain a direct readout from the recorders in situ during
