This work is made possible by data acquired by NASA, the Japanese Space Agency, and the European Space Agency, and funding support from NASA and the European Commission, through the Global Disaster Alert and Coordination System (GDACS) project, Joint Research Centre, Ispra, Italy. The Observatory was founded in 1993 at Dartmouth College, Hanover, NH USA and moved to the University of Colorado, INSTAAR, CSDMS in 2010. The institutional support of both universities is gratefully acknowledged.
