Electron Precipitation Driven by EMIC Waves: Two Types of Energy Dispersion

Geophysical Research Letters, Volume 51, Issue 9, 16 May 2024.
Abstract Electromagnetic ion cyclotron (EMIC) waves can very rapidly and effectively scatter relativistic electrons into the atmosphere. EMIC‐driven precipitation bursts can be detected by low‐altitude spacecraft, and analysis of the fine structure of such bursts may reveal unique information about the near‐equatorial EMIC source region. In this study,

On the Importance of a Geostationary View for Tropical Cloud Feedback

Geophysical Research Letters, Volume 51, Issue 4, 28 February 2024.
Abstract This study shows that geostationary satellites are critical to estimate the accurate cloud feedback strength over the tropical western Pacific (TWP). Cloud feedback strength was calculated by the simultaneous relation between cloud cover and sea surface temperature (SST) over the TWP [120°E–170°E, 20°S–20°N].
