The results of a recent gyrokinetic analysis of turbulent transport driven by the electron temperature gradient (ETG) in the MAST pedestal are presented. During the inter-ELM period, the buildup rate of the electron density gradients is faster than that of the electron temperature gradients, possibly indicating the presence of an active electron thermal transport mechanism. Local nonlinear simulations from the gyrokinetic code, GENE, show that heat flux produced by ETG turbulence is 10-30% of the total applied heating power in the upper pedestal and pedestal top during both the pre-ELM (80-99% inter-ELM period) and post-ELM (0-20%) periods. Increasing strongly with the electron temperature gradient, the ETG transport appears to be stiff. Considering radiation losses, ion thermal transport, and the strong sensitivity of the transport to the electron temperature gradient, we propose that ETG transport is a plausible mechanism mediating the inter-ELM temperature profile on MAST. Cognizant of the fact that the profiles may depart considerably from a linear approximation, we conducted global nonlinear simulations; the results are in good agreement with local simulations except near the pedestal top, where large streamers and high transport levels (far beyond experimental) develop in the local simulations. This study is a warning that when the profiles have deep structures, local simulations must be augmented /checkedby global ones. We quantify and parameterize the discrepancy between local and global simulations by calculating the ratio of the radial correlation length to a length scale representative of the profile curvature. When this ratio is sufficiently small, local and global simulations agree as expected.
