Recordings of levels of a photochemical pollutant (some kind of 
oxidant) made hourly at several recording stations in LA (by 
the LA Polution Control District). Interest lies in the relationship 
of pollutant levels to one or more meteorological variables (This 
is a small sample from a very large data set). Data recorded are 
daily maximum levels of the oxidant  over a series of days, 
together with morning averages of wind speed, temperature, 
humidity and insolation (a measure of the amount 
of sunlight) during one summer in the early 1990s. 

Collumns are

1) DAY
2) WIND SPEED
3) TEMP (F)
4) HUMIDITY (%)
5) INSOLATION
6) OXIDANT LEVEL (PPM)
