This dataset provides an example of the structure of the dataframe of
extreme events and their characteristics, as created by gen_hw_set
.
This example dataset can be used in developing custom functions to use with

A dataframe with 258 rows and 23 columns. The variables are:
hw.number: A sequential number identifying each heat wave in a city;
mean.var: Average daily temperature across all days in the heat wave, in degrees Fahrenheit;
max.var: Highest daily temperature across days in the heat wave, in degrees Fahrenheit;
min.var: Lowest daily temperature across days in the heat wave, in degrees Fahrenheit
length: Number of days in the heat wave;
start.date: Date of the first day of the heat wave;
end.date: Date of the last day of the heat wave;
start.doy: Day of the year of the first day of the heat wave (1 = Jan. 1, etc.);
start.month: Month in which the heat wave started (1 = January, etc.);
days.above.abs.threshold.1: Number of days in the heat wave above 80 degrees Fahrenheit;
days.above.abs.threshold.2: Number of days in the heat wave above 85 degrees Fahrenheit;
days.above.abs.threshold.3: Number of days in the heat wave above 90 degrees Fahrenheit;
days.above.abs.threshold.4: Number of days in the heat wave above 90 degrees Fahrenheit;
days.above.99th: Number of days in the heat wave above the 99th
percentile temperature for the city, using the period specified
by the user with the referenceBoundaries
argument in
gen_hw_set
as a reference for determining these
percentiles;
days.above.99.5th: Number of days in the heat wave above the 99.5th
percentile temperature for the city, using the period specified
by the user with the referenceBoundaries
argument in
gen_hw_set
as a reference for determining these
percentiles;
first.in.year: Whether the heat wave was the first to occur in its calendar year (Note: this characteristic is likely not useful in southern hemisphere studies.);
threshold: The temperature used as the threshold for the heat wave definition in the city;
mean.var.quantile: The percentile of the average daily mean
temperature during the heat wave compared to the city's year-round
temperature distribution, based on the temperatures for the city
during the period specified by the referenceBoundaries
argument in gen_hw_set
;
max.var.quantile: The percentile of the highest daily mean temperature during the heat wave compared to the city's year-round temperature distribution;
min.var.quantile: The percentile of the lowest daily mean temperature during the heat wave compared to the city's year-round temperature distribution;
mean.yearround.var: The city's average year-round temperature, based
on the temperatures for the city during the period specified by
the referenceBoundaries
argument in
gen_hw_set
;
mean.seasonal.var: The city's average May–September
temperature, based on the temperatures for the city during the
period specified by the referenceBoundaries
argument
in gen_hw_set
; and
city: The identifier for the city, as given in the file
specified in the citycsv
argument of
gen_hw_set
.
