  "term": "Delta Eddington",
  "field": "Meteorology and atmospheric science",
  "definition": "A two-stream approximation method used in atmospheric radiative transfer models to simplify calculations of scattering and absorption. It represents the highly forward-peaked scattering by aerosols and clouds with a Dirac delta function, while the remaining, more isotropic part of the scattering phase function is approximated by a simple two-term expansion. This approach provides an efficient way to model the transfer of solar radiation through the atmosphere, balancing computational cost and accuracy.",
