Using the recently introduced [ital g][sub 3] model for layered superconductors, we calculate the angular and temperature dependence of the upper critical field [ital H][sub [ital c]2]. By lowering the temperature we find a crossover from three-dimensional bulk behavior to decoupled two-dimensional layers in both the temperature and angular dependence of [ital H][sub [ital c]2]. This behavior is remarkably consistent with recent experiments and the comparison with the measured angular dependence provides an estimate for the interlayer coupling [ital g][sub 3].
