METEOROLOGICAL FACILITIES

To carry out its responsibilities effectively and efficiently, the Meteorological Office at KLIA is equipped with the following state-of-the art meteorological facilities:-

	Automated Weather Observation Systems (AWOS) which are installed along the two runways in KLIA. The AWOS provides automatic real-time runway visual range, wind, temperature, pressure and cloud base information to the Air Traffic Controller. This information is useful and crucial for aircraft’s safe landing and take-off.
	An Automated Weather System (AWS) which is located at the Meteorological Station at KLIA beside Runway 2 to provide automatic real-time wind, precipitation, temperature, dew point and pressure information to meteorological observers for preparing routine (every half hourly) and special weather observations reports.
	A Terminal Doppler Weather Radar (TDR) strategically installed at Bukit Tampoi, about 10 km north of KLIA for the detection and warning of wind shear and microbursts in the vicinity of KLIA. A software system is installed to generate and display TDR products.
	A Geostationary Meteorological Satellite (GMS) Receiving System to receive satellite cloud imageries transmitted from the Japanese GMS located above the equator at longitude 140 degrees East.
	A Satellite Distribution System (SADIS) which consists of a Very Small Aperture Terminal (VSAT) equipment to receive products from the World Area Forecast System (WAFS) Centre at London. The centre is one of the two world centres responsible for the generation and dissemination of global gridded binary (GRIB) data, Difax significant weather charts, wind and temperature data and text weather data such as aerodrome hourly weather reports and terminal aerodrome forecasts.
	A software system, the Meteorological Data Processing System (MDPS) for the acquisition, processing, analysis and integration of all data and product from the above systems, data and information from Global Telecommunication System (GTS), Aeronautical Fixed Telecommunication Network (AFTN) and Weather Radar Network received from the Malaysian Meteorological Service's Headquarters at Petaling Jaya as well as data from Tenaga Nasional Berhad’s National Lightning Detection Network (NLDN) to generate and display meteorological products and information. The software system also disseminates the meteorological products and information through the KLIA’s Total Airport Management System (TAMS) to the users.
	Aviation Briefing Terminals (ABT) including printers are provided at strategic locations in KLIA so that pilots, airport operators and airlines can have easy access through TAMS to various meteorological information and products relevant to their operations.
