Thermosphere Contraction Puzzles Scientists

The thermosphere layer of earth's atmosphere begins 80 to 90 kilometers above the surface and extends several hundred kilometers into the sky; it is the home to numerous satellites and the International Space Station. It is known that the thermosphere occasionally cools and contracts, but a recent study of satellite orbital decay (due to light atmospheric drag) found that the contraction during 2008 and 2009 was significantly more severe than expected, leaving researchers at a loss for how to explain it. From Space.com: "This type of collapse is not rare, but its magnitude shocked scientists. 'This is the biggest contraction of the thermosphere in at least 43 years,' said John Emmert of the Naval Research Lab, lead author of a paper announcing the finding in the June 19 issue of the journal Geophysical Research Letters. 'It's a Space Age record.' The collapse occurred during a period of relative solar inactivity — called a solar minimum from 2008 to 2009. These minimums are known to cool and contract the thermosphere, however, the recent collapse was two to three times greater than low solar activity could explain."

The atmosphere is still less than .5% CO2 today; even if it had started at 0% CO2, adding .5% concentration of something only half again as heavy (or dense, if you prefer; not that dense and heavy are synonyms but either way my point stands) as the vast majority of the atmosphere would not logically explain "the biggest contraction of the thermosphere in at least 43 years" without some serious synergy compounding the effect of that minimal impact on atmospheric density.

    it seems logical to me that increased atmospheric water is going to mean a rise in atmospheric density (possibly also increasing total internal reflection and reflection) and obviously also a lowering of overall temperature in the atmosphere (more water in the atmosphere means a higher latent heat capacity). increased density means more effect of gravity, as well as the overall drop in ambient temperature from increased heat latency.

    i'm not sure what other effects there would be from increased atmospheric water, as well as increased CO2 and reduced O2. i was thinking it may influence cloud formation patterns, alter the amount of overall radiation striking the poles and equator (via total internal reflection caused by increased atmospheric refractive index).

    in any case, i'm not that familiar with climate modelling and i'm not sure how much they count the increase in H2O in the atmosphere in their predictions, but it seems to me if we are gonna go out hunting for human influences on climate changes, then the influence of water should be, in my view, rated more highly than any other factor because of the refractive index and latent heat capacity of water, two factors that are naturally going to give it the strongest influence of any chemical in the air.

      Our production of water vapour isn't all that big an issue. There's a given amount of water vapour that can exist in the air, which depends on local pressure and temperature. If for some reason there's too much around, it rains or forms dew. If there's too little around, water on the ground evaporates until equilibrium. There's already a huge amount of water available, so if the Earth's atmosphere was capable of taking up significantly more water vapour, it would have a source from which to take it, human industry or no. On the largest scale, then, we're not adding water vapour to the atmosphere, where it would affect the greenhouse effect very significantly; we're adding liquid water to the ocean, where it makes very little difference at all.

      Carbon dioxide on the other hand is a trace gas in the Earth's atmosphere. While the industrial output of water won't affect the ocean noticeably, our output of carbon dioxide has very definitely increased the concentration of that gas in the atmosphere. Will the plants not absorb it? Possibly; carbon dioxide is good for plant life. But the exchange is much slower here. Water rains out to the ocean in an hour or two, but a great tree takes decades to grow and absorb a comparable mass of carbon. And the proportions are very different. Estimates are that we've added something like 35% to the pre-industrial levels of carbon dioxide; that would be fine if the plant biomass increased by the same proportion, so that our additional carbon was locked up in the form of wood rather than loose in the air. 35% increase in plant biomass is a lot to ask.

      i am not questioning the importance of carbon dioxide's effects, simply that the topic in question, the shrinking of the thermosphere, could be explained by the rise in available water that is soaking up the excess heat, and that the thing that this shrinkage implies to me - rising atmospheric density, is an effect that only water can possibly explain, and has effects on the radiation reaching the surface that i've not seen discussed. increased refractive index of the atmosphere, for one. this could probably be measured too, with adequately sensitive devices.

      i know that carbon dioxide is also a dense gas, but heat combined with increased available water in gas form is a factor in the equation. also, and you are not considering this, but precipitation does not always occur when temperature drops below the dew point, this is what cloud seeding is all about - just like crystals falling out of supersaturated solution, without seeding nuclei that water stays in gas form.

    The temperature of the thermosphere has nothing to do with the temperature of the climate. We're talking about the part of the atmosphere where the international space station orbits. The rules there are very different from the lower atmosphere (as are the temperatures (up to a few thousand C depending upon where you are). The temperatures are controlled by the absorption and emission of radiation (and, of course, conservation of energy).

    The radiation absorbed by these tenuous gasses is in the extreme ultraviolet and soft x-ray. We've been monitoring the solar EUV and SXR output for quite a while. When they are high the thermosphere heats up and expands. Satellites in low orbit experience a lot of drag and end up in lower orbits. Because of the extended solar minimum EUV and SXR are way down, but they haven't changed enough to explain the entire temperature difference. So the remainder of the difference has to be in the emission of radiation in the thermosphere. There's a series of linked partial differential equations involved, so I won't do the actual math. But the easiest way to cool the thermosphere is to add higher amounts of species that have a lot of cooling transitions.

    One of the people quoted in TFA thinks it might be due to increased CO2. I have a hard time buying that. Because it's heavy, it's hard to get CO2 into the thermosphere. It would be tough to get an in situ measurement of CO2 and it's ionization products with any existing instrument

    As far as what this effect could do to the world. Well, it could screw up your AM reception. And it could screw up a prediction of a LEO satellite's orbit. (i.e. your sun synchronous polar orbit might not be as sun synchronous as you hoped.) But it's not going to kill dolphins or sea turtles, or cause earthquakes or polar shifts.

    I could do the required measurement with an FUV to NUV spectrometer for diffuse radiation on 2-axis coarse pointing gimbal. I'd need a satellite for a platform. But by the time I got it built and launched we'd be heading up toward solar max.
