Function to compute the average/maximum length of dry (as defined by wet.threshold) spells

Description

Function to compute the average/maximum length of dry (as defined by wet.threshold) spells

Usage

lds(
  pr,
  dates,
  length.spell = "mean",
  wet.threshold = 1,
  year = NULL,
  year.start = NULL,
  year.end = NULL,
  pnan = 25,
  lat = NULL
)

Arguments

pr	Vector with daily precipitation
dates	Matrix containing the full range of dates corresponding to "pr" (ndates x 3 size); e.g. rbind(c(1995, 3, 1), c(1995, 3, 2), ...)
length.spell	Either "mean" or "maximum" length spell
wet.threshold	Threshold considered to define wet days. Must be in the same units of "pr"
year	Vector with years of interest (e.g. 1990:1995)
year.start	Vector of dates [in "YYYY-MM-DD" format] defining the beginning of a portion of interest within each year (e.g., the agronomic season)
year.end	Vector of dates [in "YYYY-MM-DD" format] defining the end of a portion of interest within each year (e.g., the agronomic season)
pnan	Any year with a percentage of NA data above "pnan" will be ignored
lat	Latitude (NULL) to indicate that latitude information is not used.

Value

Average/maximum length of dry spells (per year)
