Terminal Forecasts

Terminal forecasts provide critical meteorological information for specific airport locations to support takeoff, landing, and ground operations.

Terminal Aerodrome Forecasts (TAF)​

A TAF is a concise statement of the expected meteorological conditions at an airport during a specified period.

  • Duration: Typically 24 hours, increasing to 30 hours for major aerodromes.
  • Coverage: Available for all supported 4-letter ICAO airport codes.
  • History: You can request up to 7 days of historical TAFs.

Meteorological Terminal Aerodrome Reports (METARs)​

METARs are routine aviation weather reports issued at hourly or half-hourly intervals. They represent a summary of observations at a specific time.

  • SPECI: A special non-routine report issued when critical meteorological conditions change significantly between routine reports.

Take Off Data (TOD)​

TOD provides hourly forecast data for:

  • Wind
  • Temperature
  • Pressure

Available for selected airport locations to assist in performance calculations.

Runway Conditions (TALPA)​

The Takeoff and Landing Performance Assessment (TALPA) initiative reduces runway overrun risks by consistently determining runway conditions.

  • Runway Sensor Data: Sensors in the runway surface measure friction, water depth, and temperature every minute.
  • Assessment: Airports use this data to report conditions to aircraft when runways are not dry.
