What tools are used to measure weather characteristics?

Tools for measuring weather characteristics are:

1, laser cloud altimeter. By using the method of laser beam irradiating the clouds, the time between laser emission and reception is measured, so as to calculate the distance of reflection points in the clouds, and the cloud amount is determined by integrating the time.

2. Micropulse Lidar (MPL). It can measure the temporal and spatial distribution monitoring of cloud bottom and multi-layer clouds, the temporal and spatial distribution monitoring of boundary layer, the vertical distribution and temporal and spatial evolution of aerosol.

3. Forward scattering visibility meter. The transmitter and receiver are in two places with a certain angle and a certain distance. The receiver receives forward scattered light from the atmosphere. By measuring the intensity of scattered light, the scattering coefficient is obtained and the extinction coefficient is estimated.

4. Transmission visibility meter. Visibility is calculated by measuring the average extinction coefficient of horizontal air column between transmitter and receiver.

5, weather phenomenon instrument. It is an intelligent multivariable sensor, which consists of scattering visibility meter, precipitation monitoring system sensor and temperature, humidity, wind direction, wind speed and other sensors. Through the logical analysis of these data variables, we can judge the weather phenomenon.
