Re-understanding of land surface albedo and related terms in satellite-based retrievals
Big Earth Data, 2020 Land surface albedo is a critical variable in determining surface energy balance, and regulating climate and ecosystem processes through feedback mechanisms. Therefore, climatic modelers and radiative monitoring require accurate estimates of land surface

Adaptive Sampling for BRDF Acquisition
Computer Graphics Forum, EarlyView.We propose a data‐driven adaptive sampling strategy that predicts the optimal sampling pattern and count for BRDF acquisition from a single image, reducing capture time while preserving quality. Abstract The bidirectional reflectance distribution function (BRDF) describes the ratio of incoming radiance to outgoing radiance for all possible pairs of ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.Abstract We present a method for retrieving cloud optical depth that applies 3D radiative transfer to utilize the combination of polarimetry and multi‐spectral imagery that is newly available from satellite missions such as the Plankton, Aerosol, Cloud, Ocean, Ecosystem (PACE) Mission. Due to the approximate spectral invariance of scattering by clouds,

Water Resources Research, Volume 62, Issue 1, January 2026.Abstract Wetlands, though covering only 2% of the Earth's surface, store over 20% of global organic carbon, making them vital reservoirs in the global carbon cycle. Despite this significance, the role of hydrological connectivity in wetland vegetation carbon storage remains poorly understood.
