SANS: Publicly Available Daily Multi‐Scale Seismic Ambient Noise Source Maps
Journal of Geophysical Research: Solid Earth, Volume 128, Issue 1, January 2023., 2023 Abstract Seismic ambient noise sources have received increased attention recently, creating new possibilities to study the Earth's subsurface and the atmosphere‐ocean‐solid Earth coupling. In efforts to locate such noise sources using nonlinear finite‐frequency inversions, methodological developments such as pre‐computed wavefields and spatially ...

The future of Genesis science. [PDF]
Meteorit Planet Sci, 2019 Abstract Solar abundances are important to planetary science since the prevalent model assumes that the composition of the solar photosphere is that of the solar nebula from which planetary materials formed. Thus, solar abundances are a baseline for planetary science.

Space Weather, Volume 20, Issue 3, March 2022., 2022 Abstract In the past decade, significant efforts have been made in developing physics‐based solar wind and coronal mass ejection (CME) models, which have been or are being transferred to national centers (e.g., SWPC, Community Coordinated Modeling Center) to enable space weather predictive capability.

Helioseismology in the Future [PDF]
International Astronomical Union Colloquium, 1983 AbstractWe review the observables of helioseismology that can contribute to our knowledge of the physical conditions in the solar interior. We discuss the limitations which presently prevent helioseismology from reaching its ultimate goal. We finally present a list of projects which either are already underway or that are planned for the near future ...

A Multicomponent Magnetic Proxy for Solar Activity
Space Weather, Volume 19, Issue 12, December 2021., 2021 Abstract We present a new, multicomponent magnetic proxy for solar activity derived from full disk magnetograms that can be used in the specification and forecasting of the Sun’s radiative output. To compute this proxy we project Carrington maps, such as the synchronic Carrington maps computed with the Advective Flux Transport (AFT) surface flux ...

Helioseismology and solar neutrinos: an update [PDF]
, 2001 We review recent advances concerning helioseismology, solar models and solar neutrinos. Particularly we address the following points: i) helioseismic tests of recent SSMs; ii) predictions of the Beryllium neutrino flux based on helioseismology; iii ...

A Multi‐Purpose Heliophysics L4 Mission
Space Weather, Volume 19, Issue 9, September 2021., 2021 Abstract The Earth‐Sun Lagrangian point 4 is a meta‐stable location at 1 AU from the Sun, 60° ahead of Earth's orbit. It has an uninterrupted view of the solar photosphere centered on W60, the Earth's nominal magnetic field connection to the Sun. Such a mission on its own would serve as a solar remote sensing observatory that would oversee the entire ...

International Astronomical Union Colloquium, 1995 AbstractObservations of solar p-mode oscillations over the last two decades have provided a fundamentally new and unique means of probing the Sun’s interior structure. The history of understanding solar oscillations as trapped normal-mode pulsations will be briefly discussed. The large number of excited modes seen in the Sun have been used to constrain

R2O2R Improvements Identified by United States Space Weather Forecasters
Space Weather, Volume 19, Issue 6, June 2021., 2021 Abstract A communication deficit exists between the space weather research and forecast communities in the research‐to‐operations‐to‐research (R2O2R) pipeline. No formal, citable space exists for forecasters to communicate needs and lessons learned to the research community (O2R).
