Concepts
  • WEATHER STATION:  Facility where scientific studies are conducted and atmospheric phenomena are observed for the purpose of making weatherforecasts. Information gathered by weather stations and satellites is collated by computers at central departments and mathematical models.
  • SURFACE AIR TEMPERATURE:  Temperature indicated by a thermometer exposed to the open air, sheltered from direct solar radiation, placed at about 1.5m above ground.
  • REFERENCE PERIOD:  Period to which the information refers and which may be a specific day or a time interval (month, fiscal year, calendar year, among others).
