An Algorithm for Retrieval of Surface Albedo From Small View-Angle Airborne Observations Through the Use of BRDF Archetypes as Prior Knowledge

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
Land surface albedo, qualifying the ratio of the radiant flux reflected from the land surface to the incident flux, is a key forcing parameter controlling the Earth's energy budget.

Europe, We Have a Problem! Local Economic Winners and Losers of Border Closures

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT In response to COVID‐19, Schengen countries temporarily reintroduced internal border controls, disrupting cross‐border integration. Using this policy change as a natural experiment and monthly nighttime lights data, we estimate the short‐run effects on European municipalities.

Landform controls on SOC and calcite‐equivalent SIC concentrations in Caspian coastal soils: VNIR‐SWIR spectroscopy and Landsat‐8 upscaling

open access: yesSoil Science Society of America Journal, Volume 90, Issue 6, November/December 2026.
Abstract Carbon partitioning between organic and carbonate‐associated forms remains poorly constrained in arid to semiarid coastal soils, where geomorphic position, salinity, and carbonate accumulation jointly structure surface‐soil carbon patterns. We evaluated landform controls on surface (0–20 cm) soil organic carbon (SOC), calcite‐equivalent soil ...

Estimating Surface BRDF/Albedo Over Rugged Terrain Using an Extended Multisensor Combined BRDF Inversion (EMCBI) Model

open access: yes, 2022
Land surface albedo is a crucial variable of earth energy budget and global climate change. Rugged terrain significantly impacts surface bidirectional reflectance distribution function (BRDF) and the subsequent albedo retrieval using satellite remote ...

Methodology and Modeling of UAV Push-Broom Hyperspectral BRDF Observation Considering Illumination Correction

open access: yesRemote Sensing
The Bidirectional Reflectance Distribution Function (BRDF) is a critical spatial distribution parameter in the quantitative research of remote sensing and has a wide range of applications in radiometric correction, elemental inversion, and surface ...

Diminished Radiative Cooling With Northward Wildfire Advance in the East Siberian Boreal Region

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Intensification of the Siberian wildfire regime is characterized by large increases in burned area above the Arctic Circle. Wildfire in boreal forests typically reduces albedo in the decades following fire, resulting in a net cooling effect. Here we quantified changes in albedo and the accompanying radiative forcing associated with a northward

BRDF workshop

open access: yes, 2012
This thesis develops an application for interactive experiments with BRDF functions. Arbitrary BRDF function may be specified with an analytic formula, including arbitrary number of parameters. A simple scene is displayed, using specified BRDF.

Extrinsic Limitations of Stealthy Hyperuniform Devices

open access: yesAdvanced Optical Materials, Volume 14, Issue 37, 9 October 2026.
Stealthy hyperuniform devices exhibit a scattering‐free angular region whose extent follows a simple quenching equation. Experimental measurements confirm this prediction but reveal quenching efficiencies far below theoretical expectations. Multiple scattering and finite‐size effects are quantified, establishing realistic performance limits for ...

Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

open access: yesRemote Sensing in Ecology and Conservation, Volume 12, Issue 5, Page 745-762, October 2026.
Imaging spectroscopy enables large‐scale biodiversity assessment, yet spectral diversity metrics are scale dependent. Across 15 NEON ecosystems, we find that spectral richness increases sub‐linearly from 3600 m2 to 4 km2, whereas spectral divergence shows weak or inconsistent scaling with area, underscoring the importance of scale‐aware interpretation ...
