This paper aims at the long-time behavior of non-autonomous 2D Navier–Stokes equations with a class of external forces which are H-valued measures in time. We first establish the well-posedness of solutions as well as the existence of a strong uniform attractor, and then pay the main attention on the estimation of 𝜀-entropy for such uniform attractor in the standard energy phase space.
