The datasetcontains hourly measurements of air pollutant concentrations, wind speed and wind direction collectedat the Marylebone (London) air quality monitoring supersite between 1st January 1998 and23rd June 2005.Data frame with 65533 observations (rows) on the following 10 variables:list("date") Observation date/time stamp in year-month-day hour:minute:second format (POSIXct).list("ws") Wind speed, in m/s, as numeric vector.list("wd") Wind direction, in degrees from North, as a numeric vector.list("nox") Oxides of nitrogen concentration, in ppb, as a numeric vector.list("no2") Nitrogen dioxide concentration, in ppb, as a numeric vector.list("o3") Ozone concentration, in ppb, as a numeric vector.list("pm10") Particulate PM10 fraction measurement, in ug/m3 (raw TEOM), as a numeric vector.list("so2") Sulfur dioxide concentration, in ppb, as a numeric vector.list("co") Carbon monoxide concentration, in ppm, as a numeric vector.list("pm25") Particulate PM2.5 fraction measurement, in ug/m3, as a numeric vector.mydata is supplied with the openair package as an example dataset for use with documentedexamples.
