R Documentation

Example data for trajectory mapping functions

Description

The traj_data dataset is provided as an example dataset as part of the openairmaps 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.

Usage

traj_data

Format

An object of class tbl_df (inherits from tbl, data.frame) with 5432 rows and 17 columns.

Details

date: The arrival time of the air-mass
receptor: The receptor number
year: Trajectory year
month: Trajectory month
day: Trajectory day
hour: Trajectory hour
hour.inc: Trajectory hour offset from the arrival date
lat: Latitude
lon: Longitude
height: Height of trajectory in m
pressure: Pressure of the trajectory in Pa
date2: Date of the trajectory
nox: Concentration of oxides of nitrogen (NO + NO2)

pm10: Concentration of particulates (PM10)
pm2.5: Concentration of fine particulates (PM2.5)

Source

traj_data was compiled from data using the openair::importTraj() function from the openair package with air quality data from openair::importAURN() function.
