Hello
I have been trying to set up the model parameters based on flux tower observations, The observed albedo for the source area gives me an albedo of around 0.095 for the area before the leaf growth period so that would approximately be Jan-Feb-March. So I am trying to match the model outputs to give me a bulk albedo of 0.095 for that period.
Irrespective of the LAI parameters used in this model run which do not capture the growth and senescence accurately (I have not looked into that in detail yet), I have assigned the following albedo values for my model run (using SUEWS prepare)
paved: 0.10
buildings: 0.12
evergreen: 0.07 - 0.09
deciduous: 0.09 - 0.13
grass: 0.14 - 0.19
bare soil: 0.18
water: 0.10

So what I have noticed is that the modelled albedo values for vegetation (and especially for grass) are very far off the min/max limits set.
I am using supy 2022.4.7 and here are my input files

What causes this and can this be fixed without changing the LAI submodel parameters?
