Thermal Time model

as defined in Basler et al. 2016 (Agr. For. Meteorlogy) with a sigmoidal temperature response (Kramer 1994)

TTs(par, data)

Arguments

par

a vector of parameter values, this is functions specific

data

input data (see reference for detailed description), data should be formatted using flat_format()

Value

raster or vector with estimated phenophase timing (in DOY)

Examples

if (FALSE) { # \dontrun{
estimate <- TTs(data = data, par = par)
} # }
