Evaluation of E Layer Dominated Ionosphere Events Using COSMIC/FORMOSAT-3 and CHAMP Ionospheric Radio Occultation Data [PDF]
, 2020 At certain geographic locations, especially in the polar regions, the ionization of the ionospheric E layer can dominate over that of the F2 layer. The associated electron density profiles show their ionization maximum at E layer heights between 80 and ...

Validation of Sea Surface Temperature Derived From Himawari-8 by JAXA
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 Hourly sea surface temperature (SST) retrieved from Himawari-8 by the Japan Aerospace Exploration Agency (H8-SST/JAXA, latest version 1.2) is becoming an important data source for data merging as well as for resolving diurnal variation (DV). However, the

Parametrizing the time-variation of the "surface term" of stellar p-mode frequencies: application to helioseismic data [PDF]
, 2016 The solar-cyle variation of acoustic mode frequencies has a frequency dependence related to the inverse mode inertia. The discrepancy between model predictions and measured oscillation frequencies for solar and solar-type stellar acoustic modes includes ...

Identifying temporal variations in burn admissions
PLOS ONE, 2023 Background Variations in admission patterns have been previously identified in non-elective surgical services, but minimal data on the subject exists with respect to burn admissions. Improved understanding of the temporal pattern of burn admissions could inform resource utilization and clinical staffing.
