1 | landsberg_model(x, total = TRUE)
|
x |
Vector containing temperature values (Celsius-degree). |
total |
TRUE Shows the total value of accumulation, FALSE shows the value of chill-unit for each temperature (TRUE is default). |
The model is based on the subtraction of the base temperature of each hourly temperature. The temperature of the base is 5°C.
The function returns values the chill for each temperature of vector (Total = FALSE), or returns the chill accumulation (Total = TRUE).
