Abstract
The near-surface shear layer exhibits a rich medley of flows that are now being measured by time-distance and ring analysis techniques. We present comparisons of the flows obtained with the two techniques using SOI-MDI Dynamics Program data from the years 1998 and 1999. The time-distance analyses utilize f-mode data without depth inversion. The flows deduced with the two methods are remarkably similar, with common inflow and outflow sites as well as agreement in the general flow directions. The direct correspondence of features in the flows is realized in both quiet and active regions.
