Surface Albedo Assimilation and Its Impact on Surface Radiation Budget in Beijing

open access: yesAdvances in Meteorology, 2020
Surface albedo is a crucial parameter in land surface radiation budget. As bias exists between the model simulated and observed surface albedo, data assimilation is an important method to improve the simulation results.

Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

Estimating the daily mean blue-sky land surface albedo on the Tibetan Plateau using convolutional neural network

open access: yesInternational Journal of Digital Earth
Surface albedo is a critical indicator of Earth’s ability to reflect solar radiation, influencing energy balance and climate dynamics. Research on blue-sky albedo on the Tibetan Plateau has often focused on clear-sky conditions, overlooking seasonal snow

Impacts of Satellite-Based Snow Albedo Assimilation on Offline and Coupled Land Surface Model Simulations. [PDF]

open access: yesPLoS ONE, 2015
Seasonal snow cover in the Northern Hemisphere is the largest component of the terrestrial cryosphere and plays a major role in the climate system through strong positive feedbacks related to albedo.

Evapotranspiration Estimation and Irrigation Performance Assessment Using Remote Sensing: A Case Study of the Ergani Dam Irrigation System (Turkey)

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Efficient water resource management is critical for sustainable agriculture, with evapotranspiration (ET) serving as a key parameter. Remote sensing (RS) techniques offer cost‐effective approaches for ET estimation and irrigation performance assessment in extensive agricultural systems.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Evaluating Reference Evapotranspiration (ETo) Calculation Methods and Quantifying Climate‐Driven Change in Irrigation Demand Across Nepal's Terai

open access: yesInternational Journal of Climatology, EarlyView.
Framework illustrating the comparison of different reference evapotranspiration (ETo) estimation methods and the integration of baseline ETo, crop water requirement (CWR), and irrigation water requirement (IWR) calculations with downscaled CMIP6 climate projections under SSP245 and SSP585 scenarios for the mid‐century and late‐century periods across ...

Characterising City Scale Heat Climatology for Australian Climate Zones

open access: yesInternational Journal of Climatology, EarlyView.
The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...

A parameterized general model of water, ice and snow albedo

open access: yesShuili Shuiyun Gongcheng Xuebao, 2020
For frozen rivers and lakes with cold climate and frequent snowfall, the albedo of ice cover and snow cover has great influence on climate and ice thickness change.

Bias Correction of ERA5 Temperature Across Five Topoclimatic Clusters: A Comparative Evaluation of Four Methods

open access: yesInternational Journal of Climatology, EarlyView.
ERA5 near‐surface temperature over South America exhibits systematic cold biases in daily maximum temperature and warm biases in daily minimum temperature. To address the continent's strong climatic and topographic heterogeneity, South America was partitioned into five topoclimatic clusters, and four bias‐correction approaches were evaluated. The Multi‐
