Functions in climdex.pcic (1.1-1)

climdex.dtr

Mean Diurnal Temperature Range

climdex.txn

Monthly Minimum of Daily Maximum Temperature

number.days.op.threshold

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

climdex.pcic

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

climdex.tn10p

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

climdex.tnx

Monthly Maximum of Daily Minimum Temperature

climdex.r95ptot

Total Daily Precipitation Exceeding 95%ile Threshold

climdex.rx1day

Monthly Maximum 1-day Precipitation

percent.days.op.threshold

Lengths of strings of TRUE values

simple.precipitation.intensity.index

Simple Precipitation Intensity Index

get.series.lengths.at.ends

Get series length at ends

climdex.get.available.indices

Get available indices by name

climdex.tn90p

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

climdex.r20mm

Precipitation Exceeding 20mm Per Day

growing.season.length

Flexible GSL function

climdex.tx10p

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

climdex.fd

Frost Days

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.rx5day

Monthly Maximum 5-day Consecutive Precipitation

climdex.wsdi

Warm Spell Duration Index

climdex.txx

Monthly Maximum of Daily Maximum Temperature

get.last.monthday.of.year

Get the last month and day of the year

climdex.r99ptot

Total Daily Precipitation Exceeding 99%ile Threshold

threshold.exceedance.duration.index

Sum of spell lengths exceeding daily threshold

nday.consec.prec.max

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

climdex.r10mm

Precipitation Exceeding 10mm Per Day

climdex.tnn

Monthly Minimum of Daily Minimum Temperature

total.precip.op.threshold

Sum of precipitation above a threshold

ec.1018935

EC example data

climdex.rnnmm

Precipitation Exceeding A Specified Amount Per Day

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.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.

climdex.csdi

Cold Spell Duration Index

climdex.prcptot

Total Daily Precipitation

climdex.sdii

Simple Precpitation Intensity Index

climdex.quantile

Climdex quantile function

select.blocks.gt.length

Select blocks of TRUE values of sufficient length.

get.outofbase.quantiles

Method for getting threshold quantiles for use in computing indices

climdex.gsl

Growing Season Length

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

climdex.id

Icing Days

climdexInput.csv

Method for creating climdexInput object from CSV files

spell.length.max

Maximum spell length
