model.chapy.apply: Use CHAPY

Description

This page describes the usage of CHAPY with phenology(). The model specific inputs are listed and its basic functionality is explained. CHAPY was published by Ogris2020;textualbarrks and parametrized for Pityogenes chalcographus in Slovenia.

Arguments

tmin, tmean, tmax

Daily minimum/mean/maximum air temperatures in °C. For the development submodel, the parameter that is obligatory depends on mode.

daylength

Length of the day in hours. Can be created with create_daylength_rst() or create_daylength_rst().

mode

Specifies which temperature should be used to calculate the development. Can be min, mean or max.

.submodels, .onset, .diapause, .mortality, ...

See phenology() for a detailled description of the function.

Functioning

The functioning of CHAPY is identical to RITY but it is has a different parametrization.

Details

In barrks, phenology() is used to apply a model. The following code illustrates which inputs are required to apply CHAPY and which additional parameters are available.

phenology("chapy", ..., tmin = NULL, tmean = NULL, tmax, daylength, mode = 'max')

# calculate submodels separately phenology("chapy", ..., .submodels = 'onset', tmax) phenology("chapy", ..., .submodels = 'diapause', daylength) phenology("chapy", ..., .submodels = 'mortality', tmax) phenology("chapy", ..., .submodels = 'development', .onset, .diapause = NULL, .mortality = NULL, tmin = NULL, tmean = NULL, tmax = NULL, mode = 'max')
