start_of_growing_season R Documentation
Determine start of growing season
Description
This implements a conventional method for the determination of the start of
the growing season (SGS) based on daily average temperatures.
Usage
start_of_growing_season(temperatures)
Arguments
temperatures
vector Daily average temperatures in degree Celsius.
Details
A temperature sum is constructed using [weighted_temperature_sum()], i.e.
by summing the average daily temperature for each day, but applying a
weight factor of 0.5 for January and 0.75 for February.
The SGS is defined as the first day where the so constructed temperature sum
crosses 200 degree days.
