climdexInput: climdexInput
Description
The climdexInput class contains all the data necessary to compute the
climdex indices.Details
The climdexInput class consists of all the data necessary to compute
the climdex indices. Users will not need to modify any of the slots in
this class. That being said, users may want or need to repurpose this data for
further analysis. The following description of the data is aimed at that
audience.
The tmax, tmin, tavg, and prec slots are
time series of daily data of equal length and without any missing
days, with NAs in place of data where no data was present. The
dates slot is the corresponding series of dates (of type PCICt)
for the daily data.
To ease computation of monthly and annual data, monthly.factor
and annual.factor are slots in the data structure. They are
also of the same length as the time series. These can be reused for
computation of any annual or monthly aggregates.
The base.range slot contains vector of type PCICt containing
the first and last day included in the baseline.
The pctile slot contains the 95th and 99th percentile values
for the precipitation percentiles, computed on the base period.
The running.pctile.notbase slot contains the data necessary for
computing temperature based percentiles outside of the base
period. This consists of one percentile for each day of the year, computed
using an n-day (default is 5-day) running window surrounding that
day. These percentiles are computed for both the 10th and 90th
percentile for daily maximum and minimum temperature.
The running.pctile.base slot contains the data necessary for
computing temperature based percentiles inside the base period. As
this is a somewhat unpleasant operation, so are the data
requirements. Given n years of data to use as the base period, there
are n * (n - 1) sets of daily quantiles of the same type as those for
running.pctile.notbase.
