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

open access: yesJournal 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.

Which Satellite Image should be used for Mapping [PDF]

open access: yes, 2023
Today, topographical mapping based on satellite images is a standard method. With the large number of very high-resolution optical satellites, it only a question of the Ground Sampling Distance (GSD) and the map scale to be generated.

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

open access: yesSpace 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?

open access: yesGlobal 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
