    • Terrestrial Tephra Spectral Library for the Visible-Near-Infrared and Mid-Infrared Spectral Regions (ver. 1.1, April 2024)

    Metadata Updated: July 20, 2024

    Visible/near-infrared (VNIR) and mid-infrared (MIR) spectral library composed of twenty natural tephra samples from ten volcanic sources that span a range of compositions and components. The bulk, glass, and mineral phase compositions of each sample have been measured and VNIR and MIR spectra from four size fractions of each sample were collected. The VNIR spectral library has been expanded (ed. 2) to twenty-two samples.
