Demonstration

Growing Season Degree Days

gsdd() takes data frame with a date and temperature column with the mean daily water temperature in centigrade and calculates the growing season degree days (GSDD).

library(teckfish)
gsdd(gsdd::temperature_data)
#> # A tibble: 1 × 2
#>    year  gsdd
#>   <int> <dbl>
#> 1  2019 3899.

gdd calculate the growing degree days (GDD) to a date.

gdd(gsdd::temperature_data, end_date = as.Date("1972-08-30"))
#> # A tibble: 1 × 2
#>    year   gdd
#>   <int> <dbl>
#> 1  2019 3102.

gss calculates the growing season(s) (GSS).

gss(gsdd::temperature_data)
#> # A tibble: 1 × 5
#> # Groups:   year [1]
#>    year start_dayte end_dayte   gsdd truncation
#>   <int> <date>      <date>     <dbl> <chr>     
#> 1  2019 1971-03-20  1971-11-07 3899. none

gss_plots plots the temperature time series including growing season(s), moving average and thresholds.
