metar_dart 0.3.2 metar_dart: ^0.3.2 copied to clipboard
Parse Meteorological Weather reports emited from aeronautical land stations (METAR). Coming soon TAF and SYNOP.
Metar-Dart #
Inspired from python-metar, a library writed in Python language to parse Meteorological Aviation Weather Reports (METAR and SPECI).
This library will parse meteorological information of aeronautical land stations. Supported report types:
- METAR
- SPECI
- TAF
Current METAR reports #
The current report for a station is available at the URL
http://tgftp.nws.noaa.gov/data/observations/metar/stations/<station>.TXT
where station
is the ICAO station code of the airport. This is a four-letter code. For all stations at any cycle (i.e., hour) in the last hours the reports are available at the URL
http://tgftp.nws.noaa.gov/data/observations/metar/cycles/<cycle>Z.TXT
where cycle
is the 2-digit cycle number (00
to 23
).
Usage #
A simple usage example:
import 'package:metar_dart/metar_dart.dart';
main() {
String code = 'METAR MROC 071200Z 10018KT 3000 R07/P2000N BR VV003 17/09 A2994 RESHRA NOSIG';
final metar = Metar(code);
// Get the type of the report
print('${metar.type}'); // Meteorological Aerodrome Report
// Get the wind speed in knots and direction in degrees
print('${metar.wind.speedInKnot} kt'); // 18.0 kt
print('${metar.wind.directionInDegrees}°'); // 100.0°
// Get the pressure in hecto pascals
print('${metar.pressure.inHPa} hPa'); // 1014.0 hPa
// Get the temperature in Celsius
print('${metar.temperatures.temperatureInCelsius}°C'); // 17.0°C
}
