摘要：
We present equivalent width maps of the 1.98 and 2.13 mu m SO2 ice absorption hands on the surface of Io. The data were taken on 17 April 2006 with the near-infrared mapping spectrometer, OSIRIS at the W.M. Keck Observatory, Hawaii. The maps show significant regional enhancements of SO2 ice over the Bosphoros, Media, Tarsus and Chalybes Regiones. (C) 2008 Elsevier Inc. All rights reserved.
