MODIS Borne Analysis of Long Series of Radiant Fluxes at Active Lava Lakes

摘要

We report on the mid-to-long term spaceborne measurement of thermal energy radiated by volcanic, melt `lava lakes' at Nyiragongo volcano (Congo, permanent 2006-2007), and at Karthala volcano (Comoros) during its eruptive bursts of October 2000, July and August-September 2003, April and November-December 2005, May-July 2006 and January 2007. Measurements were performed on multispectral, low-resolution MODIS scenes acquired by platforms Terra and Aqua up to 4 times daily.
