Observations of ozone concentration levels.
Description
These data and subsequent description are drawn from the spTimer package (version 0.7). This data set contains values of daily 8-hour maximum average ozone concentrations (ppb; O3.8HRMAX), maximum temperature (degree Celsius; cMAXTMP), wind speed (knots; WDSP), and relative humidity (RM), obtained from 28 monitoring sites in New York, USA, between July 1 and August 31 in 2006. Each row represents a station and columns hold consecutive daily values.
Usage
data(NYOzone.dat)
Format
Columns for NYdata:
1st col = Longitude
2nd col = Latitude
3rd col = X coordinates in UTM projection
4th col = Y coordinates in UTM projection
5th col = Ozone July 1 (O3.8HRMAX.1)
6th col = Ozone July 2 (O3.8HRMAX.2)
...
66th col = Ozone August 31 (O3.8HRMAX.62)
remaining columns organize cMAXTMP, WDSP, and RH identical to the 62 O3.8HRMAX measurements
