We study the asymptotic behavior of solutions of a class of singularly perturbed nonautonomous parabolic equations defined on R n with unbounded external terms. We first prove the existence of a pullback attractor for the perturbed equation in L 2 (R n ) and then establish the upper semicontinuity o
