The Precision and Relative Accuracy of Profiler Wind Measurements

摘要: Abstract Two independent wind profiles were measured every hour during February 1986 with a five-beam, UHF (405 MHz) Profiler at Platteville, Colorado. Our analysis of the horizontal components over all heights for entire month gave standard deviation about 1.3 m s−1 measurement errors one can expect three-beam Profilers in clear air. This study demonstrated that it is important to include effects large vertical motion (caused by gravity waves or precipitation component measurements. These motions enough raise error 1.7 two-beam configurations where no corrections are made motion.
