NYOzone.dat: 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

Arguments

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
