Winds were provided by the Goddard EOS Data Assimilation System (GEOS-DAS). Flow is at the 850K isentropic level. N2O mixing ratio is expressed in parts per billion volume (ppbv).    Global N2O mixing ratio for September 6, 1992 to September 14, 1992 derived from CLAES and the GEOS-DAS Duration: 27.0 seconds Available formats:   352x240 (29.97 fps) MPEG-1   3 MB   160x80       PNG           23 KB   80x40         PNG           6 KB   320x238     JPEG         13 KB How to play our movies Animation Number: 108 Completed: 1996-03-22 Animator: Andy Acuna (Hughes STX) (Lead) Scientists: Lang-Ping Chang (NASA/GSFC)   Stephen E.
