Is there dark matter in earths atmosphere?

Yes. There's dark matter throughout the galaxy, and it passes unimpeded through solid objects.

However the distribution of dark matter might be (depending on the model) significantly affected by the gravity of solar system objects, such as the Earth. So people have discussed individual dark matter halos for the sun or the planets, or "hairs" formed by the scattering of a dark matter flux passing through the Earth. These are speculative/research arguments on how the dark matter density on Earth might be different from the galactic local average.

However, in any case, there most definitely is a certain dark matter density here on Earth.
