Calculate thermal time using cardinal temperatures
1 | thermalTime(weather, x_temp, y_temp, method = NULL)
|
weather |
WeaAna object |
x_temp |
The cardinal temperatures |
y_temp |
The effective thermal time |
method |
The method to calculate thermal time. The default method is ( maxt + mint ) / 2 - base. The three hour temperature methods will be used if method = '3hr' |
A data.frame with three columns: year, day and thermalTime.
