Height-integrated Pedersen and Hall conductivity patterns inferred from the TIROS-NOAA satellite data

摘要: The series of polar-orbiting National Oceanic and Atmospheric Administration spacecraft TIROS, NOAA 6, 7 have been monitoring the particle influx into atmosphere since late 1978. This data base has used to construct statistical global patterns height-integrated Pedersen Hall conductivities for a discrete set auroral activity ranges. observations energy “characteristic electron energy” binned in 1° latitude 2° magnetic local time grid ordered by an index. index is estimate deposited single hemisphere incident particles, parameter generated directly from and, therefore, internally consistent with that are constructed. An average spectrum associated each characteristic energy, which enables height profile ionization rate upper be determined. use pressure coordinate system insures normalized profiles independent atmospheric model parameters. To create pattern conductivities, however, vertical temperature composition assumed, ion density enhancements evaluated chemical balance between production recombination based on “effective” coefficient. can also provide heating rates over three-dimensional suitable as input more sophisticated ionospheric neutral thermospheric codes.
