ck_total_precip: Total Wet-Day Precipitation (PRCPTOT)

In climatekit: Unified Climate Indices for Temperature, Precipitation, and Drought

Total Wet-Day Precipitation (PRCPTOT)

Description

Annual or monthly total precipitation in wet days, where a wet day is a day with precipitation at or above wet_day_threshold mm (default 1 mm, the ETCCDI standard). This is the canonical ETCCDI 'PRCPTOT' definition (Alexander et al. 2006; Zhang et al. 2011).

Usage

ck_total_precip(precip, dates, period = "annual", wet_day_threshold = 1)

Arguments

precip	Numeric vector of daily precipitation (mm).
dates	Date vector of the same length as precip.
period	Character. Aggregation period: "annual" (default) or "monthly".
wet_day_threshold	Numeric (mm). Days with precipitation strictly below this threshold are excluded from the sum. Default 1.

Details

Sub-threshold trace amounts are excluded. Pass wet_day_threshold = 0 to recover the previous behaviour of summing all daily values.

Value

A data frame with columns period, value, index, and unit.

Examples

dates <- as.Date("2024-01-01") + 0:9
precip <- c(0, 5, 3, 0, 8, 2, 0, 1, 4, 0)
ck_total_precip(precip, dates)
