  "term": "Aerological days",
  "field": "Meteorology and atmospheric science",
  "definition": "Specific days designated for internationally coordinated, intensive upper-air atmospheric observations. During these periods, meteorological services conduct more frequent radiosonde launches or other soundings to gather a high-resolution dataset of the atmosphere's vertical structure over a wide area. These campaigns support special research projects, such as studying the dynamics of a particular weather system or validating new satellite instruments.",
