Soybean-BioCro circadian clock model definition

Description

Initial values, parameters, direct modules, differential modules, and a differential equation solver that can be used to run soybean circadian clock simulations in Champaign, Illinois and other locations. Along with the soybean growth specifications (soybean), these values define the soybean growth model of Matthews et al. (2022) [\Sexpr[results=rd]{tools:::Rd_expr_doi("10.1093/insilicoplants/diab032")}], which is commonly referred to as Soybean-BioCro.

To represent a soybean circadian clock in Champaign, Illinois, these values must be paired with the weather data from cmi_weather_data.

This model is described in detail in Matthews et al. (2022) [\Sexpr[results=rd]{tools:::Rd_expr_doi("10.1093/insilicoplants/diab032")}] and Lochocki & McGrath (2021) [\Sexpr[results=rd]{tools:::Rd_expr_doi("10.1093/insilicoplants/diab016")}].

Here, we use initial phases for the dawn and dusk oscillators of 200.0 and 80.0 radians, respectively. These values are optimized for simulations beginning at midnight on January 1, and should require minimal time for transient signals to die down. These values were determined by running a simulation for one year starting on January 1, and recording the oscillator states at the end of December 31.
