Inter-comparison of Vertical Profiling Instruments for Boundary Layer Measurements in an Urban Setting

摘要

A collection of surface based remote sensing instruments have been deployed In the NYC metro area for the purpose of characterizing the lower atmosphere and investigating air flow and atmospheric dispersion. With the addition of a network of rooftop surface stations and by ingesting data from various other available observational networks as well as assimilated data from modeling systems, we are able to compare the vertical profiling instruments to one another, identifying the strengths and weaknesses of the various assets that comprise the network of urban environmental observations. We compare the return signals from radar wind profilers (RWP), sodars and lidars. These comparisons allow us to calibrate the performance of similar instruments and they point out the issues that must be addressed when using non similar instruments for making similar observations.
