Abstract: 
This paper deals with the dynamical behavior of solutions for nonautonomous stochastic fractional GinzburgLandau equations driven by additive noise with $\alpha\in(0,1)$. The main difficulty is the noncompactness of Sobolev embeddings on unbounded domains, so we establish the pullback asymptotic compactness of solutions in $L^{2}(\mathbf{R}^{3})$ by the tailestimates of solutions. Consequently, we prove the existence and uniqueness of tempered pullback random attractors for the equations in $L^{2}(\mathbf{R}^{3})$. At last, we obtain the upper semicontinuity of random attractors when the intensity of noise approaches zero.
