Above the surface velocity inversions, MURaM-ARs dataset. (Left column) Patches of 50 by 50 pixels2 extracted from the 30-min-averaged transverse velocity fields vD,t(τ, ti) inferred by DeepVel at optical depths (top) τ ≈ 0.1, (middle) τ ≈ 0.01 and (bottom) τ ≈ 0.001. The time-averaged vertical velocity vref,z(τ ≈ {0.1, 0.01, 0.001}, ti) computed by the MURaM-ARs simulation and resampled to the SDO/HMI resolution is displayed as colored background. (Right column) Scatterplots comparing amplitudes ||vD,t|| to ||vref,t||. The black line represents the expected solution (i.e., a coefficient of determination R2 = 1).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
