  This paper reports on the development of reduced models for electron
temperature gradient (ETG) driven transport in the pedestal. Model development
is enabled by a set of 61 nonlinear gyrokinetic simulations with input
parameters taken from the pedestals in a broad range of experimental scenarios.
The simulation data has been consolidated in a new database for gyrokinetic
simulation data, the Multiscale Gyrokinetic Database (MGKDB), facilitating the
analysis. The modeling approach may be considered a generalization of the
standard quasilinear mixing length procedure. The parameter eta, the ratio of
the density to temperature gradient scale length, emerges as the key parameter
for formulating an effective saturation rule. With a single order-unity fitting
coefficient, the model achieves an RMS error of 15%. A similar model for ETG
particle flux is also described. We also present simple algebraic expressions
for the transport informed by an algorithm for symbolic regression.
