Atmospheric Environmental Conditions in New York City
Daily measurements of ozone concentration, wind speed, temperature, and solar radiation in New York City for 153 consecutive days between May 1 and September 30, 1973.
Environmental.df Air.df
The data frame Environmental.df has 153 observations on the following 4 variables.
ozoneAverage ozone concentration (of hourly measurements) of in parts per billion.
radiationSolar radiation (from 08:00 to 12:00) in langleys.
temperatureMaximum daily temperature in degrees Fahrenheit.
windAverage wind speed (at 07:00 and 10:00) in miles per hour.
Row names are the dates the data were collected.
The data frame Air.df is the same as Environmental.df except that the
column ozone is the cube root of average ozone concentration.
Data on ozone (ppb), solar radiation (langleys), temperature (degrees Fahrenheit), and wind speed (mph)
for 153 consecutive days between May 1 and September 30, 1973. These data are a superset of the data
contained in the data frame environmental in the package lattice.
