Spectroscopic observers found that ammonia and carbon disulfide persisted in the atmosphere for at least fourteen months after the collisions, with a considerable amount of ammonia being present in the stratosphere as opposed to its normal location in the troposphere.
Spektroskopska promatranja su otkrila da su amonijak i ugljikov disulfid ostali u atmosferi najmanje 14 mjeseci nakon udara, a značajna količina amonijaka je ostala u stratosferi u usporedbi sa njenom normalnom lokacijom u troposferi.
