<b>Conference Paper:</b> Presented at the 7th IAEA Technical Committee Meeting on H-mode and Transport Barrier Physics (Oxford, UK, September 25 - 29, 1999).</p>

<p>

We study the characteristics of self-generated zonal flows as observed in nonlinear global gyrokinetic simulations of toroidal ITG turbulence for typical parameters of DIII-D core plasmas, and discuss various possibilities for experimental measurements and the development of new diagnostics.
