What are the applications of solar radiation sensors in meteorological observations?

The application of solar radiation sensors in meteorological observations mainly includes the measurement of direct solar radiant energy and total solar radiant energy.

In meteorological observation, solar radiation sensors can be used to measure the intensity of direct solar radiation in the spectral range of 0.28-3 μm. This sensor usually consists of a high-precision sensing element, which is characterized by good stability and high precision.

At the same time, it has a quartz glass sheet mounted outside the sensing element made of precision optics cold-processed and ground, which effectively prevents environmental factors from affecting the sensor's performance.

In addition, some sensors are also built-in variable silica gel desiccant, which is convenient for users to observe the water absorption of the desiccant to ensure the normal operation of the sensor.

In addition to measuring the intensity of direct solar radiation, solar radiation sensors can also be used to measure the total solar radiation energy. Total solar radiation includes direct radiation, scattered radiation and ground reflected radiation three parts, is an important parameter in meteorological observation. Through the measurement of total solar radiation energy, can understand the distribution and change rule of solar radiation, for weather forecasting, climate change research are of great significance.

In practical applications, solar radiation sensors are usually installed in meteorological observation stations or scientific research test sites, etc., which need to take into account the installation height, observation angle and environmental factors and other influences. At the same time, in order to improve the accuracy and stability of the observation data, the sensor needs to be calibrated and maintained on a regular basis.

In short, solar radiation sensor in meteorological observation has important application value, can provide accurate data of solar radiation energy, help people better understand and master the distribution and change rule of solar radiation, for meteorological forecasting, climate change research to provide scientific basis.
