Details

These data represents a subsample of the variables included in the NMMAPS dataset for Chicago.

The variable temp is derived from the original tmpd after a transformation from Fahrenheit to Celsius. The variables pm10 and o3 are an approximated reconstruction of the original series, adding the de-trended values and the median of the long term trend. This is the reason they include negative values. See vignette('PollutantProcess') from the packages NMMAPSdata or NMMAPSlite.
