Functions in climdex.pcic (1.1-5.1)

climdex.tnn

Monthly Minimum of Daily Minimum Temperature
climdex.r10mm

Precipitation Exceeding 10mm Per Day
climdex.id

Icing Days
climdex.fd

Frost Days
climdex.rx1day

Monthly Maximum 1-day Precipitation
climdex.tx10p

Computation of these percentiles involves use of a boostrap procedure, described below but described in more depth in [Zhang, 2005].
climdex.txn

Monthly Minimum of Daily Maximum Temperature
climdex.rx5day

Monthly Maximum 5-day Consecutive Precipitation
climdexInput.raw

Any of tmin (daily minimum temperature), tmax (daily maximum temperature), tavg (daily mean temperature), and prec (daily precipitation) can be passed in. tavg will be derived from the mean of tmax and tmin if it is not supplied. If any of tmin, tmax, and prec are not supplied, the set of indices which can be calculated will be limited to indices which do not involve the missing variables.
climdex.cdd

The spells.can.span.years option specifies whether spells can cross year boundaries -- i.e., span years. The default for this is the same as for fclimdex.
climdex.tr

Tropical Nights
climdexInput.csv

Method for creating climdexInput object from CSV files
climdex.r20mm

Precipitation Exceeding 20mm Per Day
climdex.dtr

Mean Diurnal Temperature Range
climdex.cwd

The spells.can.span.years option specifies whether spells can cross year boundaries -- i.e., span years. The default for this is the same as for fclimdex.
total.precip.op.threshold

Sum of precipitation above a threshold
climdex.gsl

Growing Season Length
spell.length.max

Maximum spell length
climdex.tx90p

Computation of these percentiles involves use of a boostrap procedure, described below but described in more depth in [Zhang, 2005].
nday.consec.prec.max

Number of days (less than, greater than, etc) a threshold
climdex.sdii

Simple Precpitation Intensity Index
climdex.prcptot

Total Daily Precipitation
climdex.quantile

Climdex quantile function
ec.1018935

EC example data
climdex.su

Summer Days
climdex.tn10p

Computation of these percentiles involves use of a boostrap procedure, described below but described in more depth in [Zhang, 2005].
climdex.wsdi

Warm Spell Duration Index
climdex.r99ptot

Total Daily Precipitation Exceeding 99%ile Threshold
simple.precipitation.intensity.index

Simple Precipitation Intensity Index
get.last.monthday.of.year

Get the last month and day of the year
get.outofbase.quantiles

Method for getting threshold quantiles for use in computing indices
climdex.get.available.indices

Get available indices by name
percent.days.op.threshold

Lengths of strings of TRUE values
climdex.rnnmm

Precipitation Exceeding A Specified Amount Per Day
climdex.tn90p

Computation of these percentiles involves use of a boostrap procedure, described below but described in more depth in [Zhang, 2005].
get.series.lengths.at.ends

Get series length at ends
climdex.txx

Monthly Maximum of Daily Maximum Temperature
climdex.pcic

climdex.pcic, an implementation of the ETCCDI climate change indices.
climdex.r95ptot

Total Daily Precipitation Exceeding 95%ile Threshold
climdex.tnx

Monthly Maximum of Daily Minimum Temperature
growing.season.length

Flexible GSL function
climdexInput

climdexInput
threshold.exceedance.duration.index

Sum of spell lengths exceeding daily threshold
climdex.csdi

Cold Spell Duration Index
select.blocks.gt.length

Select blocks of TRUE values of sufficient length.
number.days.op.threshold

Number of days (less than, greater than, etc) a threshold
