Returns stratification statstics: annual mean, max and total length of summer, winter stratification and ice duration. NOTE: summer strat periods are allocated to the year in which the period starts. Winter stratification and ice periods are allocated to the year in which they end.
Usage
analyse_strat(data = NULL, Ts, Tb, dates, H_ice = NULL, drho = 0.1, NH = TRUE)
analyze_strat(data = NULL, Ts, Tb, dates, H_ice = NULL, drho = 0.1, NH = TRUE)Arguments
- data
dataframe; water temperature data in long format with date, depths, value. Defaults to NULL
- Ts
vector; of surface temperatures which corresponds to date vector
- Tb
vector; of bottom temperatures which corresponds to date vector
- dates
vector; of POSIX style date corresponding to rows of Ts and Tb.
- H_ice
vector; of ice thickness which corresponds to date vector, set to NULL if analysis not required. Defaults to NULL
- drho
numeric; density difference between top and bottom indicating stratification [kg m^-3]
- NH
boolean; northern hemisphere? TRUE or FALSE. Defaults to true
Examples
if (FALSE) { # \dontrun{
strat <- analyse_strat(Ts = df[,2], Tb = df[,ncol(df)], dates = df[,1])
} # }
