Granulated bombs of Etnean basalts were melted and the radiant energy from the melting surface was recorded by a portable spectroradiometer in the short wavelength infrared (SWIR) spectral range between 1500 and 2500 nm. The Draping algorithm, an improved algorithm for temperature and emissivity separation, was applied for the first time to SWIR hyperspectral data in order to take into account the non-uniform temperature distribution of the melt surface and, at the same time, solving the two temperatures and the spectral emissivity. The results have been validated by comparing our results with the emissivity measured at a \"lava simulator\". Basalt spectral emissivity does not vary significantly at magmatic temperature, but shows an absorption feature in the range 2180\u20132290 nm, an atmospheric window pivotal for the IR remote sensing of active volcanoes.<\/jats:p>","DOI":"10.3390\/rs12122046","type":"journal-article","created":{"date-parts":[[2020,6,25]],"date-time":"2020-06-25T10:36:54Z","timestamp":1593081414000},"page":"2046","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Temperature and Emissivity Separation \u2018Draping\u2019 Algorithm Applied to Hyperspectral Infrared Data"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3231-9636","authenticated-orcid":false,"given":"Valerio","family":"Lombardo","sequence":"first","affiliation":[{"name":"Istituto Nazionale di Geofisica e Vulcanologia, Via di Vigna Murata, 605; 00143 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonie","family":"Pick","sequence":"additional","affiliation":[{"name":"University of Hamburg, Institute of Geophysics, Bundesstr. 55, D-20146 Hamburg, Germany"},{"name":"Helmholtz Centre Potsdam, GFZ German Research Centre for Geosciences, Section 2.3 Geomagnetism; Telegrafenberg, 14473 Potsdam, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1861-5666","authenticated-orcid":false,"given":"Claudia","family":"Spinetti","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Geofisica e Vulcanologia, Via di Vigna Murata, 605; 00143 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacopo","family":"Tadeucci","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Geofisica e Vulcanologia, Via di Vigna Murata, 605; 00143 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5190-3731","authenticated-orcid":false,"given":"Klemen","family":"Zak\u0161ek","sequence":"additional","affiliation":[{"name":"University of Hamburg, Institute of Geophysics, Bundesstr. 55, D-20146 Hamburg, Germany"},{"name":"ROSEN Group, Am Seitenkanal 8, 49811 Lingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"268","DOI":"10.1109\/36.17668","article-title":"Land-surface temperature measurement from space: Physical principles and inverse modeling","volume":"27","author":"Wan","year":"1989","journal-title":"IEEE Trans.
