Correct adjectival form of the word "disperse"

Question

I am writing an article related to the ionosphere and I would like to ask what form of the word disperse is right in the sentence:

A significant majority of the error can be easily removed using two or
more frequencies due to the disperse nature of the ionosphere.

I looked at few dictionaries and googled the combination "disperse nature". Here is what I found:

▶adjective: Chemistry denoting a phase dispersed in another phase, as in a colloid. – derivatives
dispersal noun,
disperser noun,
dispersible adjective
dispersive adjective.

And for example http://www.yourdictionary.com/disperse-system

disperse system
A disperse system is a two-part system made up of microscopic particles and the medium in which they are suspended. (noun)

Here, if I am not mistaken, the word disperse is used as an adjective.

I am not an English native speaker and I have no sense in this. What is the right form for my sentence?

I believe dispersive is your best bet:

1: of or relating to dispersion a dispersive medium, the dispersive
  power of a lens
  2: tending to disperse

So you'd have

A significant majority of the error can be easily removed using two or
  more frequencies due to the dispersive nature of the ionosphere.

(-) Is the ionosphere, itself, disperse?
If yes, then because past participles can be adjectives, I would write "dispersed".
ex: "100% distilled water does not have a dispersed nature."

(-) Is the ionosphere not dispersed, but the ionosphere causes dispersion, then I would use "dispersive":
ex: "With regard to light diffraction, 100% distilled water has a dispersive nature."

"Disperse" is a suitable adjective; the opposite of "dense".

I am surprised nobody suggested 'sparse' as an alternate word.
