Jan. 28, 2013 — In what is believed to be the first study of its kind, researchers used genomic techniques to document the presence of significant numbers of living microorganisms -- principally bacteria -- in the middle and upper troposphere, that section of the atmosphere approximately four to six miles above Earth's surface.
We have demonstrated that our technique works, and that we can get some interesting information," Nenes said. "A big fraction of the atmospheric particles that traditionally would have been expected to be dust or sea salt may actually be bacteria. At this point we are just seeing what's up there, so this is just the beginning of what we hope to do."

well this is pretty interesting if they are actual microbes that live all the time in the atmosphere this could mean that there are other small creatures up there

I wonder if they could be brought up in the evaporation process?
Or if they are living in floating colonies?
Simultaneous sampling for microorganisms was accomplished at altitudes of 690, 1,600, and 3,127 meters. The location of temperature inversions in relation to the collection altitude determined, to a great extent, the micropopulation. High micropopulations were found when an inversion was above the sampling altitude, and low populations when the inversion was below the sampling altitude. Diurnal periodicity which could be generally correlated with periods of minimal and maximal convective activity was observed. Evidence is presented showing that the micropopulation is more stable at higher altitudes than at lower altitudes.

I've always wondered that.
Makes my theory on the space critters seem a little more plausible.
