We present thermal measurements made by high spatial resolution ground-based (a hand-held thermal camera) and low spatial resolution space-based (MODIS) instruments for a lava flow field active during the last phase of the May-July 2003 eruption at Piton de la Fournaise (La R,union). Multiple oblique ground-based thermal images were merged to provide full coverage of the flow-field. Our results underscore the importance of ground-based thermal analysis for the interpretation of satellite measurements, particularly in terms of calculating discharge rate trends.

Abstract

We present thermal measurements made by high spatial resolution ground-based (a hand-held thermal camera) and low spatial resolution space-based (MODIS) instruments for a lava flow field active during the last phase of the May-July 2003 eruption at Piton de la Fournaise (La R,union). Multiple oblique ground-based thermal images were merged to provide full coverage of the flow-field. Our results underscore the importance of ground-based thermal analysis for the interpretation of satellite measurements, particularly in terms of calculating discharge rate trends.
