Gillet writes in the K-theory handbook that Chow groups are analogous to the singular homology of a CW complex, and one may ask what would be a good analogue of singular cohomology. Note that for a CW complex which is a manifold, we have Poincare duality, so there is no essential difference - in the algebraic geometry setting this question is interesting for singular varieties???
According to Gillet there are at least two reasonable notions of Chow cohomology. One is Operational Chow groups and the other is sheaf cohomology of K-theory, which I think is what people call K-cohomology. He discusses formal properties of these two choices. For example the second one is not homotopy invariant for singular varieties, but can be made homotopy invariant by using instead a simplicial smooth hyperenvelope. Simplicial hyperenvelopes also give a weigh filtration on K-cohomology, and the weight zero part of this filtration recovers Fulton’s operational Chow groups. Simplicial hyperenvelopes require characteristic zero I think.
See Gillet section 6 for more details.
