摘要: The stratosphere accumulates the bulk of meteoric and cometary material that impacts Earth provides a measure flux. Recent models measurements effective age stratospheric air demonstrate our ability to simulate this buildup. Current observations H2O in mesosphere are consistent with an extraterrestrial source H2O, but limit its influx less than 2 Tg/yr. Such flux is standard estimates 100 times small-comet hypothesis.
