摘要在过去的十年中，各种类型的遥感器对影响中尺度区域空气质量的气象过程的研究做出了越来越大的贡献。多普勒声雷达和激光雷达以及新出现的915兆赫雷达风廓线技术，以及描述平均风和温度廓线。一些空气质量实地研究方案现已在中尺度实验中以各种组合方式部署了这些仪器。三项研究提供了讨论平均风和温度廓线的例子。遗憾的是，许多遥感仪器尚未充分发挥其测量湍流动量和热通量以及混合层深度的潜力。一个简单的四波束多普勒声学系统提供了一个初步的例子，这种潜在的应用。此外，模式识别方法，虽然主观的性质，可以适用于时间-高度截面的反射率与数据的使用中的色散的解释…
Abstract Remote sensors of various types have contributed increasingly over the past decade to studies of meteorological processes affecting air quality over mesoscale domains. Doppler sodars and lidars as well as newly emerging 915-MHz radar wind profiler technology are shown to describe well mean wind and temperature profiles. A number of air quality field research programmes have now deployed these instruments in various combinations in mesoscale experiments. Three studies provide examples for discussion of mean wind and temperature profiles. Unfortunately, many remote sensing instruments have not realized their full potential for measurement of turbulent momentum and heat fluxes as well as mixed-layer depth. A simple four-beam Doppler acoustic system provides a preliminary example of such potential applications. Furthermore, pattern-recognition methods, although subjective in nature, can be applied to time-height cross sections of reflectivity with the data of use in the interpretation of dispersion p...
