Recent Trends in Inverse Rendering

Computer Graphics Forum, EarlyView.
This survey reviews 84 papers published between 2020 and 2025 on inverse rendering methods, introducing a taxonomy based on input data, scene representations, optimization strategies, and evaluation methods. We analyze emerging trends in neural, differentiable, and Gaussian‐splatting approaches, discuss applications, and identify key challenges and ...

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

Ibis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

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

IEEE 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.

The Role of Vegetation Clumping in Regulating Global Heat Fluxes Accounting for Land‐Atmosphere Coupling

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The Clumping Index (CI) critically regulates canopy radiation, yet its role in reshaping global heat fluxes under land‐atmosphere (L‐A) interactions remains poorly quantified. We integrated satellite‐derived CI into the Community Earth System Model (CESM) to assess its impacts through L‐A coupled simulations.

Burn Severity as a Driver of Multi‐Year Increases in Gross Primary Production and Solar‐Induced Fluorescence Following a Wildfire in Arctic Tundra

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract While climate‐driven increases in wildfires are altering the composition and function of Arctic ecosystems, the impact of burn severity on longer‐term changes in community composition and ecosystem fluxes remains less understood, creating uncertainty in estimates of the biome's carbon storage capacity.

The Timing of Albedo Declines With Reforestation

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Reforestation is a leading climate solution for removing carbon dioxide from the atmosphere, but generally decreases surface albedo, which diminishes its climate mitigation value. Knowing how quickly this albedo effect unfolds relative to carbon removal is critical for planning climate mitigation actions, yet the temporal changes in albedo are

Intercomparison of Global Solar Induced Chlorophyl Fluorescence Products

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Satellite observations of Sun‐Induced Chlorophyll Fluorescence (SIF) provide a powerful means to assess terrestrial photosynthesis at regional to global scales, yet major SIF products differ in retrieval strategy, radiometric stability, and sensitivity to environmental conditions.

Reversal of Temperature Sensitivity in Vegetation Greenness Rates Along Aridity Gradients Across Global Ecoregions

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Drought is increasingly reshaping terrestrial ecosystems under climate change, yet how aridity modulates the climatic sensitivities of satellite‐derived green‐up rate (GR) and senescence rate (SR) in natural ecosystems remains poorly understood at the global scale. Here, we combine two decades of satellite observations and climate data sets to
