| Zusammenfassung |
| The variation of parameters in time series data from the EISCAT UHF
incoherent scatter radar has been used to estimate the uncertainties in
measurements of electron concentration, electron and ion temperature and
line-of-sight ion velocity. Good agreement was found with the results of
previous analyses that estimated uncertainties in velocity and electron
temperature from similar data using a complementary method. By contrast,
uncertainties in ion temperature and electron concentration estimated from
the same time series data were found to differ from the expected theoretical
values by factors of 1.8 and 2.7, respectively. It was found that the
relative sizes of these uncertainties more closely matched those predicted
by a previous Monte Carlo simulation than values predicted by currently
accepted theoretical formulae. Although the specific measured and
theoretical uncertainties reported here relate to a very simple kind of ISR
experiment, the method itself is general and can be applied to data from any
incoherent scatter radar. |
