Scientific paper

In view of the usefulness of IR remote sensing for radiometry of hot volcanic features, a procedure has been developed for solving a three-component model of lava surface temperatures on the basis of three IR observations. The procedure is demonstrated through the use of Thematic Mapper Simulator data recorded over Mount Etna in 1991. Improved estimates of radiant emittance are obtainable by constraining temperatures and pixel-filling fractions of the three different thermal components in this fashion.
