The microwave radiometer (SMR-100) is a ground-based microwave remote sensing device that uses microwave signals received from atmospheric radiation to judge changes in atmospheric temperature and humidity. Together with cloud radar and wind profile radar, it forms a complete atmospheric vertical profile detection system, which can detect changes of meteorological elements such as temperature, humidity, wind speed and wind direction over the city in real time. Weather forecasters grasp the weather changes at any time according to the detected information, refine the weather forecast and warning, and provide accurate data support for the weather forecast and warning of sub-(residual) games.

Meterscatter aerosol Lidar (MPL-5000) can continuously monitor the distribution and spatiotemporal evolution of atmospheric aerosols. The device can monitor the changes of air pollutants over the venue in time, and understand the air environment conditions and trends of the venue.
