More and more and more...
Saturn40 has finished the final 40eV GS run. This has been analysed, recoded and set off as an SD run. Analysis raises the 40eV grade to a first.
Some research done on Martian aurora. Altitude is about 129km, cf Martim altitude range of about 60-250km. Have got hold of a quick 1D Martian atmosphere to do a few runs on, but more cross-sections are required, as ever. The species involved are CO2, N2, O2, O, CO, NO and Ar. From the Earth, cross-sections are provided for N2, O2, O and Ar. This leaves CO2, CO and NO in need of some data, slightly unfortunate as the main emitting species is CO2 and other bands of interest include CO bands. Nevertheless, a quick browse about has netted a few cross-sections and as I know the names of the bands I need to work with, I can grab them - or at least have a better idea of where to look. A current and energy distribution have also been uncovered, suggesting a number flux can be determined, meaning I can then simulate a few emissions, see if they lie in the right area and are of the correct magnitude, then a more complex look should provide interesting things. Interesting things to look at include band emission ratios and the effect of pitch angle on all this, as field aligned electrons seem not to be dominant, apparently. We shall see.
The Martian atmosphere is a lot thinner than the Earth's, this means the number densities cover a very small altitude range, which in turn means a fast running program, hopefully. The low energy and flux of electrons involved in the Martian aurora should also help in that...
Atmosphere extrapolated. Tomorrow, I will create the program base.
