Methodology Investigation Calibration and Quality Control for New Meteorological Instrumentation. Part 1.

摘要

U.S. Army Dugway Proving Ground (DPG) conducted tests to verify performance and develop quality control procedures for new meteorological instrumentation. The instrumentation tested included cup and sonic anemometers, Doppler acoustic sounders (sodars), and a crosswind scintillometer. Sonic anemometer intercomparison tests conducted at the Boulder Atmospheric Observatory (BAO) identified deficiencies in the DPG sonic anemometer software. These deficiencies are being corrected by the manufacturer. The sonic anemometer transducer shadow correction algorithm was characterized in a low turbulence wind tunnel. It's response in turbulent flow was then compared to the response of cup anemometers. These tests verified the sonic anemometer's transducer shadow correction algorithm. A novel means of evaluating cup anemometer overspeeding was developed from cup versus sonic anemometer intercomparisons.
