Galileo's photopolarimeter-radiometer instrument mapped
Io's thermal emission during the I24, I25, and I27 flybys with a
spatial resolution of 2.2 to 300 kilometers. Mapping of Loki in I24
shows uniform temperatures for most of Loki Patera and high
temperatures in the southwest corner, probably resulting from an
eruption that began 1 month before the observation. Most of Loki Patera
was resurfaced before I27. Pele's caldera floor has a low temperature of 160 kelvin, whereas flows at Pillan and Zamama have temperatures of
up to 200 kelvin. Global maps of nighttime temperatures provide a means
for estimating global heat flow.
