Oscillatory Phase and Acoustic Travel-Time Inconsistencies Measured between SDO/HMI and GONG Dopplergrams
Junwei Zhao, Ruizhu Chen, S. P. Rajaguru +1
We investigate the causes of discrepancies in meridional-circulation measurements derived from the helioseismic observations by the Helioseismic and Magnetic Imager onboard the Sol…
Solar-cycle variations in meridional flows and rotational shear within the Sun's near-surface shear layer
Anisha Sen, S. P. Rajaguru, Abhinav Govindan Iyer +3
Using solar-cycle long helioseismic measurements of meridional and zonal flows in the near-surface shear layer (NSSL) of the Sun, we study their spatio-temporal variations and conn…
Hemispheric Magnetic Asymmetry and Cross-Equatorial Circulation Cells within the Sun's Near-Surface Shear Layer
Anisha Sen, S. P. Rajaguru, Ruizhu Chen +2
Using time-distance helioseismic measurements of meridional flow in the near-surface shear layer over a period of 14 years, starting from May 2010, we probe the depth structure and…
Probing the Sun's Near Surface Shear Layer using HMI Spherical Harmonic Coefficients
Sushanta C. Tripathy, Kiran Jain, Shukurijon Kholikov +1
We have measured zonal and meridional components of subsurface flows up to a depth of 30 Mm below the solar surface by applying the technique of ring diagram on Dopplergrams which…
The Multiview Observatory for Solar Terrestrial Science (MOST)
N. Gopalswamy, S. Christe, S. F. Fung +54
We report on a study of the Multiview Observatory for Solar Terrestrial Science (MOST) mission that will provide comprehensive imagery and time series data needed to understand the…
Camera update for GONG refurbishment: Development and validation
Anna L. H. Hughes, Timothy J. Purdy, Thomas M. Wentzel +9
This report provides a brief summary of the properties of new cameras selected for NSF's Global Oscillations Network Group (GONG) facilities operated by the NSO Integrated Synoptic…
