    Description: The interaction of solar wind with Earth’s magnetosphere supports various Ultra-Low- Frequency (ULF: 1mHz-few Hz) wave modes. In our study, we model the natural modes of oscillations in the Earth’s magnetic field using an analytic and numerical approach. The model provides solutions to the spatial and temporal structures of the ULF waves in the dipole field geometry for realistic density variations. The results of the analytic model match well with the numerical solutions. The provision of inclusion of finite ionospheric conditions in the model makes the model applicable to different local times, seasons, and regions of the magnetosphere. The model is validated with observations from satellite and ground-based magnetometer data. The observations and model together are able to reproduce the salient features of Earth’s magnetosphere. The model is extended to the Jovian magnetosphere to reproduce the field line eigen modes observed from Galileo flybys and crossing of JUNO satellite crossing over Ganymede.

    Toward a Cenozoic history of atmospheric CO2 (2023)
    In:  Science
    Details
    Publication Date: 2024-02-12
    Description: The geological record encodes the relationship between climate and atmospheric carbon dioxide (CO2) over long and short timescales, as well as potential drivers of evolutionary transitions. However, reconstructing CO2 beyond direct measurements requires the use of paleoproxies and herein lies the challenge, as proxies differ in their assumptions, degree of understanding, and even reconstructed values. In this study, we critically evaluated, categorized, and integrated available proxies to create a high-fidelity and transparently constructed atmospheric CO2 record spanning the past 66 million years. This newly constructed record provides clearer evidence for higher Earth system sensitivity in the past and for the role of CO2 thresholds in biological and cryosphere evolution.
