  "id": "MLC-T-MET-005659",
  "term": "Flux emissivity",
  "field": "Meteorology and atmospheric science",
  "definition": "A measure of the efficiency with which a surface emits thermal radiation, defined as the ratio of the radiant flux emitted by a real surface to the radiant flux emitted by a perfect blackbody at the same temperature. It is a dimensionless quantity ranging from 0 to 1. Different surfaces, like snow, vegetation, or bare soil, have varying flux emissivities.",
