A radar rain sensor is a sensor that utilizes the radar principle to measure rainfall. It utilizes radar technology to measure the microwave signals reflected back from rainfall, so as to obtain information such as the size, number and speed of raindrops, and then calculate the intensity and amount of rainfall. Compared with the traditional rain gauge, the radar rain sensor has the advantages of wide measurement range, high precision, real-time and so on, and can provide complete rainfall information, which provides powerful support for weather forecasting, disaster prevention and mitigation.


The working principle of radar rain sensor is similar to that of conventional radar, which detects rainfall by transmitting microwave signals and receiving the reflected signals back. Usually, the radar rain sensor will choose the microwave with stable frequency and lower power, which can reduce the interference to the raindrops and avoid the measurement error.


In addition to measuring rainfall, radar rainfall sensors can also provide information on other precipitation characteristics, such as precipitation type, precipitation rate and spatial distribution, etc., which helps to determine the development trend of meteorological phenomena and the pattern of change, and plays an important role in meteorological forecasting and disaster warning. In the field of meteorological forecasting, hydrological forecasting and natural disaster monitoring, radar rain sensor has become an important monitoring tool.


Rainfall data is one of the important data that often need to be used in the field of meteorology and hydrology. Rainfall data can be used in the following occasions-


Hydrology: Rainfall data is one of the very important data in the field of hydrology. It can provide the data needed in the field of hydrological cycle and water resource management, such as spatial and temporal distribution of rainfall, rainfall intensity, flood flow, etc. It is the basic data for hydrological forecasting and water resource management.


Meteorology: Rainfall data is one of the important meteorological elements in meteorology and weather forecasting, and can provide basic data for the analysis and research of meteorological phenomena.


Agricultural production: Good rainfall data can provide an important basis for agricultural production. It can help farmers to better plan farming programs, adjust crop planting time, planting area and fertilizer application and other plans to improve crop yields and ensure the productivity and stability of agriculture.


Urban flood control: rainfall data for urban flood control work has a very important role. It can help the urban planning department to understand the rainfall situation, determine the construction planning, drainage facilities construction and flood warning and other important work.


Climate change research: rainfall data is one of the important data in climate change research, which can provide basic data for the research of climate change trend. By comparing and analyzing the rainfall data within a certain time range, the evolution of the climate can be better understood.


In conclusion, rainfall data are widely used in many fields such as hydrology, meteorology, agricultural production, urban flood control and climate research, providing an important basis for decision-making and research in related fields.
