NASA Picks Two Missions to Explore Venus, the First in Decades
WebJan 1, 2024 · To derive emissivity we use lookup tables of Venus thermal emission radiance spectra calculated by the atmospheric radiative transfer model created by Tsang et al. (2008) based on the work of Kamp et al., 1988, Irwin, 1997. The model assumes a plane parallel atmosphere and includes atmospheric absorption, emission and multiple … WebApr 1, 2024 · The NIR emissivity of Venus’s surface can constrain rock types and their weathering state; emissivities can be measured directly or calculated from reflectances.
