1. Tab 1 SENSITIVITY ANALYSIS stb_stn Objective: We choose here an inclined or flat plane domain to perform plot scale simulations, to check the sensitivity of the energy balance partition to slope, vegetation properties, initial conditions. Simulations name: stb_stn Results folders: - Results elaborations in: /Users/giacomo/EURAC/Stubai/Results/stb_stn/stb_stn.ppt - Figures saved in: /Users/giacomo/EURAC/Stubai/Results/stb_stn/Figures/ - Matlab elaborations in: /Users/giacomo/GeoMatlab/Mfiles_points/ load_sensitivity.m plot_sensitivity.m - Input inclined DTM in: /Users/giacomo/EURAC/Stubai/Inputs/Piano.xls - Parameters settings in: /Users/giacomo/EURAC/Stubai/Inputs/Inpts_stb_stn004.xls - Simulations index in: /Users/giacomo/EURAC/Stubai/Simulations/sim_stb_stn.txt Simulation assumptions: - Flat (or inclined) 11x11 dtm - Forcing as stb_tot simulations (Clear sky days in September 1999) - Reference simulation with intermediate parameters (stb_stn004f) zo=0.1 m; do=0.66 m fc=0.5 (for all parameters see 'sensitivity' in Inpts_stb_stn004.xls) - Saturated initial conditions, 10 days spin up. - Soil parameters as in Neustift station soil (very organic soil at the surface).

Fig 10 Sensitivity to soil thermal properties effect on surface temperature stb_stn013-015 k_solid = 8.5 W/(m K) c_solid = 2.16 E6 J/(m^3 K) k_solid = 0.5 W/(m K) c_solid = 2.16 E6 J/(m^3 K) k_solid = 0.5 W/(m K) c_solid = 1 E6 J/(m^3 K) k_solid = 8.5 W/(m K) c_solid = 1 E6 J/(m^3 K) Strong effect of soil conductivity on surface temperature , especially the night ones (low soils with low conductivity, as limestone and organic ones (or dry grass) have very low nocturnal skin temperatures and higher daily ones)
