metars-tafs

Get latest METARs and TAFs by ICAO code from Aviation Weather Center

Installation

yarn add @airport-discovery/metars-tafs

Usage

The module exposes two main functions, which accept an ICAO string or an array string of ICAOs

METARs

const airportDiscovery = require('@airport-discovery/metars-tafs');
const metars = await airportDiscovery.metars('LIMC'); // ICAO for Malpensa Airport (MXP)

Output

{
  "rawText": "LIMC 181720Z 28003KT 1500 BR BKN001 06/06 Q1027 NOSIG",
  "latitude": "45.62",

  "temperatureC": "6.0",
  "dewPointC": "6.0",
  "wind": {
    "directionDegrees": "280",
    "speedKt": "3"
  },
  "visibilityStatuteMi": "0.93",

  },
  "flightCategory": "LIFR",

}

Or multiple ICAO codes

const airportDiscovery = require('@airport-discovery/metars-tafs');
const metars = await airportDiscovery.metars(['LIMC', 'LTFM']);
