Assimilation of N2O in the Upper Atmosphere Using a Kalman Filter: Error Correlation
This series of animations shows assimilation of N2O in the upper atmosphere using observations from the Cryogenic Limb Etalon Spectrometer (CLAES) on the Upper Atmosphere Research Satellite (UARS). 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).
Error Correlation between a material particle and all other grid points for September 6, 1992 to September 14, 1992 derived from CLAES and the GEOS-DAS
