【摘要】 本文重点介绍北京320米气象观测塔上进行平均场垂直梯度测量的自动化设备,并介绍各层安装的风向、风速、温差以及地面温度仪等的性能。塔上大量数据输入两种自动化处理系统。一种是将各层平均风向、平均风速、温差以垂直廓线的形式记录在电子电位差计上;另一种是将上述瞬时资料以及其它快速感应信号送入DJS-130电子计算机进行处理。更多还原

【Abstract】 An automatic measurement system of the 320 meters meteorological tower is described. This system is being designed to provide the vertical structure of the meteorological elements that will meet the research objectives of the air pollution and the atmospheric boundary layer.Sensors to be described are the sensors of temperature at the ground, temperature difference between tw.o levels, wind speed and direction. In addition, the feature of automatic data processing system is described. This system can be divided into two groups according to the desired sampling rate. One is for the form of profile of the mean wind speed, wind direction and temperature differece. The other is to sent the instantaneous data and signals of the fast response sensors.更多还原
