Functions in climdex.pcic (1.1-1)
Search functions
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
climdexInput
climdexInput
climdex.su
Summer Days
climdex.tr
Tropical Nights
climdex.tx90p
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
