Abstract : Under a prior Air Force (AFGL) program two prototype Automated Present Weather Sensors were developed. The present program supported hardware and software upgrades Sensors were developed. The present program supported hardware and software upgrades to those sensors which were intended to achieve two objectives. The first and primary objective was to improve the performance capability of the sensors to meet the performance specifications of the NWS-ASOS and FAA-AWOS automated present weather observing systems. The second objective was to provide additional sensor capabilities beyond those required for ASOS/AWOS systems, which improvements would be of value in Air force applications of present weather sensors. Tests made on the sensors after the upgrades were performed, demonstrated their capability to now meet three of the four basic requirements for ASOS/AWOS present weather sensors, namely: (1) precipitation detection, (2) false alarm rate, and (3) precipitation identification. Their ability to meet the fourth requirement; i.e., rainrate accuracy, could not be verified for lack of adequate reference standards. (rh)
