  "term": "Extinction coefficient",
  "field": "Meteorology and atmospheric science",
  "definition": "A measure of how strongly a substance absorbs or scatters light at a specific wavelength per unit path length. It quantifies the reduction in intensity of electromagnetic radiation as it passes through a medium, such as the atmosphere. This coefficient is a key parameter in radiative transfer calculations and is expressed in units of inverse length, such as per meter or per kilometer.",
