### Description

`O3` | daily maximum of the hourly average ozone concentrations in Upland, CA
`vh` | 500 millibar pressure height, measured at the Vandenberg air force base
`wind` | wind speed in mph at LAX airport
`humidity` | humidity in percent at LAX
`temp` | Sandburg Air Force Base temperature in degrees Fahrenheit
`ibh` | temperature inversion base height in feet
`dpg` | pressure gradient from LAX to Daggert in mm Hg
`ibt` | inversion base temperature at LAX in degrees Fahrenheit
`vis` | visibility at LAX in miles
`doy` | day of the year

### Source

This dataset was copied from `library(faraway)` and the name changed to `ozone1` to prevent a name clash. The data were originally made available by Leo Breiman who was a consultant on a project where the data were generated. Example analyses using these data may be found in Faraway and in Hastie and Tibshirani.
