This data is obtained by the automatic weather station of CR1000 data collector produced by Beijing Huayi Technology Co., Ltd. The original data is subjected to strict calibration steps to generate end-user data, Among them, the temperature and humidity sensor hmp155a has a wide range of applications, providing reliable measurement of relative humidity (RH) and temperature; the direct radiation sensor nr01 consists of four heads to measure the surface radiation balance. The measurement principle is thermopile sensor. Nr01 can produce four very small voltage outputs when measuring, and the output voltage is proportional to the income and expenditure of short wave and short wave. Nr01 consists of four heads The net radiation sensor composed of radiometer is studied with scientific energy balance; wind speed and direction sensor 05103 is a high-performance wind sensor with strong durability and corrosion resistance; t-200b is used for total precipitation monitoring, which can record real-time precipitation and cumulative precipitation; sr50a ultrasonic snow depth sensor is a sound wave newly developed by Campbell company The distance sensor measures the distance by measuring the time when the ultrasonic pulse is transmitted and returned.
