Spectral Extension of the CPF‐Measured Earth‐Reflected Solar Radiances for CPF‐CERES Intercalibration

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 4, 28 February 2025.
Abstract The Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder (CPF) mission is set to launch an SI‐traceable reflective solar (RS) spectrometer aboard the International Space Station to measure Earth‐reflected solar radiation with a radiometric uncertainty of 0.3%–0.6% (k = 1).

Extended detailed balance modeling toward solar cells with cement‐based radiative coolers

Progress in Photovoltaics: Research and Applications, Volume 33, Issue 1, Page 54-63, January 2025.
This work extends the detailed‐balance model commonly used to assess radiative coolers for solar cells by incorporating the impact of Auger and Shockley–Read–Hall nonradiative recombination and of a thermal contact resistance at the cell/cooler interface.

Land Surface Longwave Radiation Retrieval from ASTER Clear-Sky Observations

Remote Sensing
Surface longwave radiation (SLR) plays a pivotal role in the Earth’s energy balance, influencing a range of environmental processes and climate dynamics. As the demand for high spatial resolution remote sensing products grows, there is an increasing need

Control of Groundwater‐Lake Interaction Zone Structure on Spatial Variability of Lacustrine Groundwater Discharge in Oxbow Lake

Water Resources Research, Volume 61, Issue 1, January 2025.
Abstract Lacustrine groundwater discharge (LGD) is an important water and nutrient source for lakes. Despite its importance, high‐resolution quantifying the spatial variability of LGD remains challenging. Particularly, little studies have explored the impact of the interaction zone structure between lakes and aquifers on this variability. Present study

Feasibility of Quantum Key Distribution Between Supersonic Aircraft

IET Quantum Communication, Volume 6, Issue 1, January/December 2025.
Quantum key distribution (QKD) leverages the laws of quantum mechanics to enable the secure transfer of information and is the only known method of key exchange capable of providing verifiable security. We first survey the academic literature and identify gaps in research relating to airborne QKD, establishing a foundation for our own study ...

Earthshine as an Illumination Source at the Moon

, 2019
Earthshine is the dominant source of natural illumination on the surface of the Moon during lunar night, and at locations within permanently shadowed regions that never receive direct sunlight.

Radiometric calibration of UAV multispectral images under changing illumination conditions with a downwelling light sensor

The Plant Phenome Journal, Volume 7, Issue 1, December 2024.
Abstract Unmanned aerial vehicle (UAV)‐acquired multispectral images commonly suffer from radiometric inaccuracies due to changing illumination produced by intermittent cloud cover. This study addressed cloud shadow effects by integrating direct irradiance measurements from a downwelling light sensor into reflectance calculations.
