摘要：

The multispectral auroral images from the Dynamics Explorer satellite are used to construct maps of auroral electron energy deposition, mean energy, and ionospheric conductances. An auroral model is used to infer conductances from brightness ratios of different spectral emissions. We briefly describe this method and its limitations, and apply the analysis to eight pairs of auroral images obtained sequentially over a period of 1 h 30 min during an intense substorm on 22 November 1981. The derived conductance patterns exhibit large variability in time and considerable structure within the auroral oval.
