quadrifolia leaflets have a very high absorptance and detrichomed treatments did not affect the visible part (400-700 nm) of optical properties of the leaflets (Fig.
53 kW) when the shade absorptance was increased from 18% to 27% for a constant reflectance of 70%.
The bolometer can be calibrated at selected wavelengths with the HACR and its overall spectral response characteristics inferred from knowledge of its relative spectral absorptance.
To extend the uncertainty analysis to the NIR, one has to check the absorptance by the chromium oxide coated receiver cavity in the NIR.
While all 156 tunable parameters provided through the project website are too extensive to list here, a majority of the parameters were for building material properties such as thickness, conductivity, density, specific heat, thermal absorptance, and solar absorptance, and visible absorptance for materials such as gypsum board, stone, concrete foundation wall, fiberglass insulation, metal roofing, plywood, insulation, gravel, oriented strand board (OSB), and cladding, as well as U-factor, solar heat gain coefficient, and visible transmittance for window glazing systems.
Calculating the area ratios or absorptance weighted area ratios is easy and fast.
Four transmittance values for roller shades: 1%, 3%, 5% and 7% (shade absorptance 20%).
where: [alpha] is the absorptance, [rho] is reflectance, A is area, l is solar radiation, and n is the total opaque surface number.
