This java lib provides a Metar decoder.

Use the MetarFacade class and its method decode to decode a metar. Use the MetarFacade class and its method retrieveFromAirport to get the metar of an airport. This metod take the icao code as parameter. The trends of the metar are not parsed.

The application contains numerous enumarations to represent datas.

• CloudType: to represent the type of cloud.
• CloudQuantity: to represent the amount of clouds.
• Intensity: to represent the intensity of a meteorological phenomenon.
• Descriptive: to represent the descriptive of a meteorological phenomenon.
• Phenomenon: to represent a phenomenon.

• a list of phenomenon

The wind class is composed of

• the speed

• the speed of the gust
• the lowest variable wind
• the highest variable wind
• the unit of the wind's speed

Instantiate the metarFacade and use its method parse.

String code = "LFPG 131830Z 19005KT 170V250 9999 -SHRA FEW040TCU SCT086 16/08 Q1011";
MetarFacade facade = MetarFacade.getInstance();
Metar metar = facade.decode(code);

Instantiate the metarFacade. Use the its method retrieveFromAirport with the ICAO code of the airport.

String icao = "LFPG";
MetarFacade facade = MetarFacade.getInstance();
Metar metar = facade.retrieveFromAirport(icao);
