The long time behavior of solutions of the nonautonomous three-components reversible Gray-Scott system defined on the entire space is studied when the external forcing terms are unbounded in a phase space. The existence of a pullback global attractor for the equation is established in and , respectively. The pullback asymptotic compactness of solutions is proved by using uniform estimates on the tails of solutions on unbounded domains.
