traj_data

The <code>traj_data</code> dataset is provided as an example dataset as part of the
<code>openairmaps</code> package. The dataset contains HYSPLIT back trajectory data for
air mass parcels arriving in London in 2009. It has been joined with air
quality pollutant concentrations from the "London N. Kensington" AURN urban
background monitoring site.

datasets

Combine the air quality data analysis methods of 'openair'
with the JavaScript 'Leaflet' (<https://leafletjs.com/>) library.
Functionality includes plotting site maps, "directional analysis"
figures such as polar plots, and air mass trajectories.
