ozone

ozone is a simple wrapper around the NOAA national weather service's publicly exposed ozone levels. It parses the values from http://airquality.weather.gov/probe_aq_data.php and returns them in json form.

How to use it:

Require forecast.io

var Ozone = require('ozone');
var ozone = new Ozone();

Make a call to the API using the get method.

ozone.get(latitude, longitude, function (err, res, data) {
  if (err) throw err;
  log('res: ' + util.inspect(res));
  log('data: ' + util.inspect(data));
});

Data is returned in an object with a data property, which is an array of objects each containing time, an eight hour average, and a one hour average. All ozone levels are marked in parts per billion.
