WebSep 11, 2024 · I have a question on substitution of ALB/LAI/GVF in WRF V4.0. As for these three, I can replace the equivalent fields through usemonalb = true, rdlai2d = true, and sst_update=1 in namelist.input. we are using albedo from TBL, lai from TBL, but GVF (VEGFRAC) from monthly MODIS. This is verified from wrfout* files. WebJan 9, 2024 · SCAF is used to weight the ground emissivity and ground surface resistance. It also affects the computed snow surface albedo that is modelled using the biosphere–atmosphere transfer scheme (BATS). BATS (Yang & Dickinson, 1996 ) models direct and diffusive radiation in visible and near-infrared bands separately accounting for …
WebThis gives an effective temperature of 6 °C on the surface of the Earth, assuming that it perfectly absorbs all emission falling on it and has no atmosphere. The Earth has an albedo of 0.3, meaning that 30% of the solar radiation that hits the planet gets scattered back into space without absorption. WebAug 1, 1987 · The model was statistically derived using in situ sea-sudace temper- atures and, therefore, is applicable for sea-surface temperatures or surfaces whose emissivity is equivalent to that of the sea surface (i.e., the emissivity of the sea surface in the 10-12-/~m band is ap- proximately 0.99 according to Buettner and Kern (1965), Griggs (1968 ...
