摘要
区域气象站是为进行加密观测而布设的自动气象站,其主要进行温度、雨量、风向、风速的观测、数据采集和数据传输。作为野外观测的气象观测仪器,容易受到恶劣环境的影响而降低测量性能,同时各要素传感器的测量准确度也会随时间的变化而发生漂移。因此,定期开展区域站仪器的核查工作非常重要。为了保证区域气象站探测数据的可用性和仪器的稳定性,需要业务人员在设备安装、巡检、维护、维修或更换部件后进行现场核查。考虑到现场核查工作的复杂性和不稳定性,介绍了GRZ3800精密数字温度计、 JJS2型雨量校准仪、JJE10型风向核查仪、JJE3型风速校验仪等现场核查设备的工作原理,详细阐述了各设备的现场核查方法,并对方法中的一些难点和疑点进行解读。这些设备具有高精度、高稳定性、智能型和便携式等特点,非常适用于区域气象站的现场核查工作。
The regional weather station is an automatic weather station that is deployed for encrypted observation. It is mainly used to observe temperature, rainfall, wind direction, wind speed, data acquisition and data transmission. As a meteorological observation instrument for field observation, it is easy to be affected by harsh environment and the measurement performance may degrade. At the same time, the measurement accuracy of each element sensor may drift with time. Therefore, it is very important to carry out verification work for regional instruments regularly. In order to ensure the availability of the detection data of the regional weather station and the stability of the instruments, it is necessary for the business staff to perform on-site verification after equipment installation, inspection, maintenance, repair or replacement of components. Considering the complexity and instability of the on-site verification work, the working principle and instruction of GRZ3800 precision digital thermometer, JJS2 rain gauge calibrator, JJE10 wind direction verifier, JJE3 wind speed calibrator and other on-site verification equipment are introduced. The on-site verification method of each device is described in detail, and some difficulties and doubts in operation are interpreted. The devices are highly accurate, highly stable, intelligent and portable, they are suitable for on-site verification of regional weather stations.
