a meteorological data.frame specific to biomasse.


The Winter Wheat Dry Matter model (WWDM) is a dynamic crop model running at a daily time step (Makowski et al, 2004). It has two state variables, the above-ground winter wheat dry matter U(t), in g/m^2 and the leaf area index LAI(t) with t the day number from sowing (t=1) to harvest (t=223). In the multisensi package implementation, the biomasse function simulates the output for only one parameter set (the first row of input if it is a matrix or a data.frame).
