摘要: In the presented work, spectral emissivity of basaltic melts at magmatic temperatures was retrieved in a laboratory-controlled experiment by measuring their radiance. Granulated bombs Etnean basalts were melted and radiant energy from melting surface recorded portable spectroradiometer short wavelength infrared (SWIR) range between 1500 2500 nm. The Draping algorithm, an improved algorithm for temperature separation, applied first time to SWIR hyperspectral data order take into account non-uniform distribution melt and, same time, solving two emissivity. results have been validated comparing our with measured "lava simulator". Basalt does not vary significantly temperature, but shows absorption feature 2180–2290 nm, atmospheric window pivotal IR remote sensing active volcanoes.
