In (date), a new Grothendieck topology was introduced by S. Lichtenbaum, defined on the category of schemes of finite type over a finite field. Its construction bears the same relation to the étale topology as the Weil group does to the Galois group.

The Weil-étale site

Weil-étale sheaves and cohomology

The Lichtenbaum conjectures

It was conjectured that the Weil-étale cohomology groups could be used in computing values of zeta functions.
