摘要: We present a new temperature map obtained from an analysis of Cassini/CIRS (Composite Infrared Spectrometer) spectra acquired in limb geometry February 2010. compare this to that 2005 and 2006 data. find drastic cooling (21K) the stratosphere around 1-mbar level between two dates cannot be explained by seasonal effect. also show equatorial oscillation has moved downward 1‐1.5 scale height 4.2 years.
