The statistical properties are presented for the direct numerical simulation of a self-similar adverse pressure gradient (APG) turbulent boundary layer (TBL) at the verge of separation. The APG TBL has a momentum thickness-based Reynolds number range from 570 to 13, 800, with a self-similar region from 10, 000 to 12, 300. Within this domain the average non-dimensional pressure gradient parameter beta = 39. These properties are compared to those of a beta = 0 and 1 case.


The statistical properties and KE budgets of these three flows in the domain of interest are provided as ASCII files.
