  "id": "MLC-T-MET-008077",
  "term": "Potential density",
  "field": "Meteorology and atmospheric science",
  "definition": "The density a parcel of fluid would have if it were moved adiabatically and isentropically to a reference pressure level, typically the surface. This concept removes the effect of compressibility on density, allowing for a more accurate comparison of water masses at different depths. It is a key parameter in oceanography for analyzing water mass stability and circulation.",
