  "id": "MLC-T-MET-004283",
  "term": "Chlorine monoxide dimer",
  "field": "Meteorology and atmospheric science",
  "definition": "A molecule formed by the reversible dimerization of two chlorine monoxide (ClO) radicals, typically denoted as ClOOCl. This compound serves as a temporary reservoir for stratospheric chlorine, particularly at low temperatures in the polar regions. Its photolysis by ultraviolet radiation releases atomic chlorine, which then catalyzes ozone destruction.",
