Pyranometer – solar radiation sensor (PYR)

Pyranometers are high-precision sensors used to measure total solar radiation coming from the sky, including direct sunlight and diffuse radiation from the atmosphere. Measurements are presented in W/m² (watts per square meter), which represents the amount of solar energy reaching the Earth’s surface. These sensors are crucial for applications in meteorological and climatological research, energy production, as well as in agriculture.

 

Pyranometers and Evapotranspiration

In agriculture, pyranometers play an important role in calculating evapotranspiration (ET) – the process of water evaporation from the soil and transpiration through plants. By accurately measuring solar energy, pyranometers help estimate the amount of water plants lose, which is essential for optimizing irrigation systems. The data collected by the pyranometer is used in calculations, such as the Penman-Monteith equation, to determine the required amount of water for crops.

Importance in Agriculture

Monitoring evapotranspiration with pyranometers helps farmers manage irrigation more efficiently, reducing unnecessary water usage while ensuring optimal growing conditions for plants. This is especially important in regions with limited water resources. Proper irrigation management not only improves crop yields but also conserves water, contributing to the sustainable development of agricultural practices.
