Calculates snow phenology from the snow water equivalent data

First snow melt, first continuous snow melt, first snow accumulation and continous snow accumulation are reported.

snotel_phenology(df, threshold = 0, offset = 180)

Arguments

df

a snotel data file or data frame

threshold

threshold for mapping continuous snow cover

offset

offset of the year relative to January first (DOY 1)

Details

Be sure to execute this code on individual sites when loading a combined tidy data frame containing data for multiple sites.

Examples

if (FALSE) { # \dontrun{
# download one of the longer time series
df <- snotel_download(site_id = 670, internal = TRUE)

# calculate the snow phenology
phenology <- snotel_phenology(df)

# show a couple of lines
head(phenology)

} # }
