Modified method of Ford and Labosier (2017)

Description

Besides the additional duration criteria (at least 3 pentads under 30th p.) we also added two new criteria: 1. Events with onset out of the growing season (MAMJJASO) are not considered as flash droughts 2. Evetns that are 3 pentads or less apart are considers the same event.

Usage

FordLabosier_gs(vtime, vswc, crit = c(40, 20, 30))

Arguments

vtime

data frame column or vector containing date data

vswc

data frame column or vector containing soil water content values

crit

a vector of three value (default c(20,40,30)) indicating the model thresholds for lower, upper and persistance limits for SWC percentiles.

Value

A list with two data frames, one a time series with all data for FD identification, and the second with a summary of FD events.

Examples

FD_events <- FordLabosier_modif(de_tha_d$time, de_tha_d$soil_water, crit = c(40,20,30))
