Instrålning

Instrålning is a Swedish term that translates to "irradiation" or "insolation" in English, depending on the context. It generally refers to the process of exposing something to radiation.

In the context of environmental science and meteorology, instrålning specifically denotes the solar radiation that reaches the Earth's surface. This includes both direct sunlight and diffuse radiation scattered by the atmosphere. The amount of solar instrålning an area receives is influenced by factors such as latitude, time of day, season, cloud cover, and atmospheric transparency.

Instrålning is a fundamental driver of Earth's climate system. It provides the energy for photosynthesis in plants, drives atmospheric circulation, and influences surface temperatures. Variations in solar instrålning are a key component of weather patterns and seasonal changes. Measuring and understanding instrålning is crucial for climate modeling, renewable energy assessments (particularly for solar power), and agricultural planning.

Beyond meteorology, instrålning can also refer to the exposure of materials or living organisms to other forms of radiation, such as ionizing radiation used in sterilization or medical treatments. However, without further context, the term most commonly implies solar radiation.
