Description:
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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spencer, J R -- Rathbun, J A -- Travis, L D -- Tamppari, L K -- Barnard, L -- Martin, T Z -- McEwen, A S -- New York, N.Y. -- Science. 2000 May 19;288(5469):1198-201.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lowell Observatory, 1400 West Mars Hill Road, Flagstaff, AZ 86001, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10817987" target="_blank"〉PubMed〈/a〉
