image: These are thermal images acquired with VISIR (16) on the VLT on Jan. 19, 2011, sensitive to Saturn's tropospheric temperatures (10.7 and 18.7-μm, 200-500 mbar) and stratospheric temperatures (8.6 and 12.3-μm emission from methane and ethane, respectively, sensitive to the 1-10 mbar level), compared to a visible-light RGB image from T. Barry (left, from IOPW-PVOL (13) data base). For more information, please see Figure 1 in the manuscript. This image relates to an article that appeared in the May 19, 2011, issue of Science Express, published by AAAS. The study, by Leigh Fletcher at University of Oxford and colleagues, was titled, "Thermal Structure and Dynamics of Saturn's Northern Springtime Disturbance." view more
