The mydata dataset is provided as an example dataset as part of the openair package. The dataset contains hourly measurements of air pollutant concentrations, wind speed and wind direction collected at the Marylebone (London) air quality monitoring supersite between 1st January 1998 and 23rd June 2005. The data set is a tibble.
mydataData frame with 65533 observations (rows) and 10 variables:
Observation date/time stamp in year-month-day hour:minute:second format (POSIXct).
Wind speed, in m/s, as numeric vector.
Wind direction, in degrees from North, as a numeric vector.
Oxides of nitrogen concentration, in ppb, as a numeric vector.
Nitrogen dioxide concentration, in ppb, as a numeric vector.
Ozone concentration, in ppb, as a numeric vector.
Particulate PM10 fraction measurement, in ug/m3 (raw TEOM), as a numeric vector.
Sulfur dioxide concentration, in ppb, as a numeric vector.
