kokonaissäteilyn

Kokonaissäteily refers to the total amount of solar radiation incident on a horizontal surface. It encompasses both direct and diffuse solar radiation. Direct solar radiation is the sunlight that travels in a straight line from the sun to the surface. Diffuse solar radiation is sunlight that has been scattered by atmospheric particles such as clouds, aerosols, and air molecules.

The intensity of kokonaissäteily varies significantly depending on several factors, including geographical location, time of day, season, and atmospheric conditions. For example, locations closer to the equator generally receive higher amounts of kokonaissäteily than those at higher latitudes. During summer months, the sun's angle is higher in the sky, leading to increased radiation compared to winter. Cloud cover can drastically reduce kokonaissäteily by scattering and absorbing sunlight.

Kokonaissäteily is a crucial parameter in various fields. In meteorology, it influences atmospheric temperature and weather patterns. In the field of renewable energy, particularly solar energy, understanding kokonaissäteily is essential for designing and optimizing solar power systems, such as photovoltaic panels and solar thermal collectors. Accurate measurements and estimations of kokonaissäteily are also important for agricultural applications, such as crop growth modeling, and for environmental studies related to climate change and Earth's energy balance. Instruments like pyranometers are commonly used to measure kokonaissäteily.
