Near-Surface Shear Layer Workshop
COFFIES Community Workshop Series '23
Fri Nov 03, 2023 09:00 - 14:00 PDT
Let’s talk about the Near-Surface Shear Layer (NSSL)
Solar activity is a Consequence of Fields and Flows in the Interior and Exterior of the Sun (COFFIES). COFFIES is a NASA Heliophysics DRIVE Science Center working to advance our understanding of how the Sun generates the quasi-cyclic magnetic field that extends throughout the heliosphere. Please join COFFIES DRIVE Science Center researchers online for the second annual series of one-day workshops focused on the Tachocline, Flux Transport & Emergence (FT&E), and the Near-Surface Shear Layer (NSSL).
The Near-Surface Shear Layer extends 5-10% of the way into the convection zone, and processes all of the magnetic flux and plasma passing through it. Two sessions address observations and modeling of temporal and spatial variations of the NSSL, with a third looking at its relationship to both deep and shallow dynamo processes.
