| Apr 10, 2018 at 13:47 | comment | added | Bob Jacobsen | Not enough for a true Answer, but perhaps it’ll help somebody: there’s a significant difference in atmospheric density (at 100’s of km altitude) with latitude. That would be a twice-per-orbit effect. It also has a day-night difference. The only non-pay walled paper I have handy is Newton&Pelz: agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/JA074i016p04169 | |
| Apr 10, 2018 at 12:52 | comment | added | uhoh | @NathanaelVetters the strong feedback in atmospheric reentry makes the problem much more unpredictable. At 400 km the ISS only looses about 10 meters or less per orbit, so that kind of exponential behavior isn't really a good model here. | |
| Apr 10, 2018 at 12:25 | comment | added | Nathanael Vetters | Remember Tiangong-1? Even the day before they changed the predicted time of impact to serval hours later because of lack of expected solar activity. So it sounds like there is a pretty significant amount of variation, though I don't have any numbers. | |
