Abstract:

Ceiling and visibility measurements are included in an Automatic Weather Observing System (AWOS) which is intended to satisfy the needs of aviation. The performance of one ceilometer and two visibility sensors was examined to determine whether they can meet the requirements of AWOS systems. The visibility sensors employed two different principles of operation: a transmissometer and a forward-scatter meter. The sensors were field tested at Arcata CA, Sterling VA, and Otis Air National Guard Base MA. During the last portion of the field testing the sensors were interfaced to a commercially available AWOS system to verify the sensor interfaces. The results of the evaluation indicate that the laser ceilometer and the transmissometer were generally satisfactory, but that the forward-scatter meter required additional development and testing because of electronic defects in the units tested. A major goal of the study was to develop and evaluate acceptance test procedures for AWOS ceilometers and visibility sensors. Accuracy and maintenance requirements, standard reference, sensors, and test methods were examined.
