Format

1	Month: 1 = January, ..., 12 = December
2	Day of month
3	Day of week: 1 = Monday, ..., 7 = Sunday
4	Daily maximum one-hour-average ozone reading
5	500 millibar pressure height (m) measured at Vandenberg AFB
6	Wind speed (mph) at Los Angeles International Airport (LAX)
7	Humidity (%) at LAX
8	Temperature (degrees F) measured at Sandburg, CA
9	Temperature (degrees F) measured at El Monte, CA
10	Inversion base height (feet) at LAX
11	Pressure gradient (mm Hg) from LAX to Daggett, CA
12	Inversion base temperature (degrees F) at LAX
