What is meteorological station?

Meteorological station is a professional equipment to collect, analyze and process weather data. By collecting and analyzing temperature, humidity, air pressure, light, rainfall, dew point, wind speed, wind direction and other meteorological elements, it predicts climate change and responds to various meteorological disasters.

The overall appearance of a meteorological station consists of a stand-alone pole supporting various weather sensors and the collection mainframe at the top. Usually the perimeter and top of the installation site are away from buildings and other obstructions to ensure the accuracy of the measurement data.

Meteorological station components

Meteorological monitoring systems generally consist of measurement unit, power supply system and control unit.

Measurement unit

Meteorological monitoring station derive their data from individual weather sensors. A completed meteorological station monitoring system includes the following sensors:

  • Temperature humidity sensor
  • Wind speed sensor/wind direction sensor
  • Solar radiation sensor
  • Rain gauge
  • Rain and snow sensor
  • UV sensor
  • Dew point sensor
  • Solar radiation shield
  • Gas sensor
  • Soil sensor

1. Temperature and humidity sensor

In order to prevent the impact of direct sunlight and rain erosion on the measurement data, the sensor is placed in a solar radiation shielding cover to monitor the temperature and relative humidity in the environment. Temperature and humidity are the most basic elements in meteorological research. There are many types of temperature and humidity sensors, such as resistive, capacitive, thermal, etc.

Monitoring wind speed and direction is a standard part of every weather monitoring system. Whether it is agriculture, navigation or transportation fields need to measure wind speed and direction. Wind speed and wind direction sensors work to strictly ensure that there is no obstruction around, so as to ensure that the data is true and effective. There are various types of wind speed and direction sensors such as mechanical, ultrasonic, magneto-electric and so on.

5. Climate research

Equipment used to measure the intensity or energy of solar radiation. Solar radiation sensor can be divided into total radiation sensor, direct radiation sensor, scattered radiation sensor. According to different wavelength ranges, it can also be divided into visible radiation sensors, ultraviolet radiation sensors, infrared radiation sensors and so on. Solar radiation sensors are generally installed on horizontal or inclined platforms to facilitate the reception of sunlight, while avoiding shading and reflection from surrounding objects.

Equipment used to measure precipitation. Rain gauge can be divided into two categories of mechanical and electronic, mechanical rain gauge is mainly funnel type, bucket type, float type. Electronic rain gauge is mainly photoelectric, acoustic wave, radar and so on. Mechanical rain gauge structure is simple, inexpensive, but need to manually clean up and read data regularly. Electronic rain gauge structure is complex, high price, but can realize automation and remote observation and transmission.

It is to measure the phenomenon of rainfall and snowfall equipment. Divided into two kinds with automatic heating function and no heating function. Both need to be installed at an angle to avoid water stagnation on the surface leading to icing.

Equipment used to measure the intensity or index of ultraviolet light. UV sensors can be divided into two categories: broadband and narrowband. Broadband UV sensors can measure the intensity of radiation across the entire UV band, and narrowband UV sensors can measure the intensity of radiation in a specific wavelength range. UV sensors are generally mounted on horizontal or inclined platforms to facilitate the reception of sunlight, while avoiding shading and reflection from surrounding objects.

It is a device that can directly measure the dew point temperature. Its data also reflects the humidity of the climate. Typical dew-point sensors are thin-film capacitive, resistive, and chilled-mirror.

8. Other sensors

Common other sensors, such as atmospheric pressure sensor, illuminance sensor, noise sensor, etc. are placed in the solar radiation shield. Solar radiation shield is a device used to protect the weather sensor, it consists of a number of shutters, can effectively block the sun, rain and other external factors on the sensor interference, while maintaining good ventilation performance, so that the sensor inside and outside the air temperature is similar. In addition, other gas sensors, soil sensors, etc. are added as needed.

Power supply system

The meteorological station can support both power supply and solar power supply. Power supply usually only requires connecting the power cord to the host. The solar power supply system consists of solar panels, lead-acid batteries, waterproof boxes and controllers.

Control unit

The monitoring mainframe collects data by connecting to each weather sensor, uploads the data and supplies power to the sensors. At the same time, it can give commands to the monitoring platform. The process of data transmission relies on the cooperation of the monitoring host and various signal/power cables.

Why is meteorological station important?

1. Predict the weather

The meteorological station can be used to record a variety of weather data from the ground, atmosphere and oceans, including temperature, humidity, barometric pressure, wind direction and wind speed. Rainfall, snowfall, sunshine and ground temperature can also be measured. With these data, meteorological stations can predict future weather conditions. For example, meteorological stations can predict storms, typhoons, tornadoes and other natural disasters. This can help the government and the public to take the necessary measures so as to minimize casualties and property damage caused by weather.

2. Agricultural production

The meteorological station also have a significant impact on agricultural production. In the context of global warming and climate change, farmers need accurate weather forecasts to select appropriate crop varieties and planting times. Meteorological stations can collect and transmit data so that farmers can plan and manage crop yields based on weather forecasts.
