In MartinHoldrege/precipr: Manipulating and examining precipitation intensity

Description

Generate daily precipitation on wet days based on gamma distribution described by mean and SD in the params dataframe

Usage

generate_events(df, params)

Arguments

df	dataframe, output from markov_chain() function
params	dataframe of parameters from monthly_ppt_params() function or from adjust_params() function

Value

dataframe with PPT_cm (daily precip) column added

Examples

params <- monthly_ppt_params(wx_data)
df <- markov_chain(params)
df2 <- generate_events(df, params)
# calculate yearly ppt (original data is 31.6 cm)
df2 %>% dplyr::group_by(year) %>%
dplyr::summarize(PPT_cm = sum(PPT_cm)) %>%
dplyr::summarize(PPT_cm = mean(PPT_cm))
