actinometria
Actinometria is the measurement of actinic radiation, which refers to electromagnetic radiation that is capable of causing photochemical reactions. This typically includes ultraviolet (UV) radiation, but can also encompass visible light and infrared radiation depending on the specific application and definition used. The primary goal of actinometria is to quantify the intensity or flux of this radiation.
Instruments used for actinometria are called actinometers. These devices vary widely in their design and sensitivity,
Actinometria has applications in various scientific and industrial fields. In meteorology and climatology, it is used
