Statistical Assessment of Accuracy and Precision in Satellite Spatial Quality Measurement Using Natural Edge Targets from KOMPSAT-3A

Remote Sensing
The spatial quality (RER, FWHM, MTF50, and MTFA) of an on-orbit high-resolution Earth observation satellite was statistically assessed using edges extracted from natural targets in urban imagery, rather than from a ground-based artificial edge target ...

Comprehensive Analysis of Bias in TEMPO NO₂ Column Densities Through Pandora Observations. [PDF]

J Geophys Res Atmos
Abstract Tropospheric Emissions: Monitoring of Pollution (TEMPO) is the first geostationary satellite instrument to monitor air pollutants across North America. This study uses Pandora observations to analyze the bias in TEMPO Level‐3 total column density of NO2 (TOTNO2) from August 2023 to December 2024.

On the Impact of Thermal Gradients Across Fluxgate Sensors on In Situ Magnetic Field Measurements

Journal of Geophysical Research: Space Physics, Volume 128, Issue 6, June 2023., 2023
Abstract Fluxgate magnetometers are an important tool for measuring space plasmas. In situ magnetic field investigations often involve measuring small perturbations of a large background field, so robust instrument calibration is critical to accurately resolving geophysical signals.

Disappearance of the Polar Cap Ionosphere During Geomagnetic Storm on 11 May 2019

Space Weather, Volume 20, Issue 6, June 2022., 2022
Abstract Multi‐instrument data from Jang Bogo Station (JBS) in Antarctica were utilized to study ionospheric responses to the 11 May 2019 moderate geomagnetic storm. These include Vertical Incident Pulsed Ionospheric Radar (VIPIR)/Dynasonde, Fabry‐Perot Interferometer (FPI), GPS vertical total electron content (vTEC), and magnetometer.

Are Land‐Use Change Emissions in Southeast Asia Decreasing or Increasing?

Global Biogeochemical Cycles, Volume 36, Issue 1, January 2022., 2022
Abstract Southeast Asia is a region known for active land‐use changes (LUC) over the past 60 years; yet, how trends in net CO2 uptake and release resulting from LUC activities (net LUC flux) have changed through past decades remains uncertain. The level of uncertainty in net LUC flux from process‐based models is so high that it cannot be concluded that
