Light and Radiation

The light and climate radiation sensors They are essential in meteorology and climatology to measure the quantity and intensity of solar radiation that falls on the Earth's surface. These data are essential for understanding the Earth's energy balance, studying climate change and optimizing applications such as agriculture and solar energy generation.

Types of Radiation Sensors:

1. Pyranometers:
   • Operation: They measure global solar irradiance, i.e. the sum of direct, diffuse and reflected radiation reaching a surface. They are composed of a thermocouple or a photovoltaic cell that converts the radiation into a proportional electrical signal.
2. Ultraviolet Radiation (UV) Pyranometers:
   • Operation: They measure the intensity of UV-A and UV-B radiation reaching the Earth's surface. These sensors are designed to detect specific wavelengths associated with ultraviolet radiation.
3. Spectral Solar Radiation Sensors:
   • Operation: They measure solar radiation in different spectral bands, providing detailed information on the spectral distribution of solar radiation.
4. Diffuse Radiation Sensors:
   • Operation: They measure the solar radiation that reaches the surface after being scattered by molecules and particles in the atmosphere.
5. Solar Radiation Sensors for Agriculture:
   • Operation: They measure the solar radiation that falls on plants, which is crucial for evaluating photosynthesis and plant growth.
