Career Rose was born in 1944 in Detroit, Michigan to William Ingersoll Rose and Mary Jane (nee Brown). At the age of five, Rose moved with his family to Corrales, New Mexico. He studied geography and geology at Dartmouth College from 1962-1966, graduating with a BA.

Rose also spent periods as visiting scientist or visiting fellow at NCAR, USGS, Volcanological Survey of Indonesia, Cascades Volcano Observatory and Bristol University. He worked extensively on volcanic gas and ash emissions from volcanic systems, and on processes in volcanic plumes, and on the detection of ice in eruption plumes from remote sensing data. and edited several books on the topics of volcanism and hazards in that region.

Recognition and awards Rose was awarded the 2002 N. L. Bowen Award of the American Geophysical Union for his contributions to geosciences, volcanology and remote sensing.
