Smoggy is a ruby library for fetching air quality data from AirNow.gov.
An API key is required to access the AirNow API. Getting an API key is easy. Just create an account at AirNowAPI and request an API key. Store the API key the config/secrets_file.yml file or set the ENV['AIRNOW_API_KEY'] variable.
cp config/secrets_file.yml.example config/secrets_file.yml
# save the API key in config/secrets_file.yml
# OR
ENV['AIRNOW_API_KEY'] = <some_api_key>

bbox = Smoggy::BoundingBox.new(sw, ne)
data = Smoggy::Airnow.new.aqi_with_bounding_box(bbox)
