Investigation of Urbanization Effects on Land Surface Phenology in Northeast China during 2001–2015

open access: yesRemote Sensing, 2017
The urbanization effects on land surface phenology (LSP) have been investigated by many studies, but few studies have focused on the temporal variations of urbanization effects on LSP.

Localized Augmentation of Net Precipitation to Shrubs: A Case Study of Stemflow Funneling to Hummocks in a Salinity-Intruded Swamp

open access: yesFrontiers in Forests and Global Change, 2021
The interception of precipitation by plant canopies can alter the amount and spatial distribution of water inputs to ecosystems. We asked whether canopy interception could locally augment water inputs to shrubs by their crowns funneling (freshwater ...

Improving the Estimation of Daily Aerosol Optical Depth and Aerosol Radiative Effect Using an Optimized Artificial Neural Network

open access: yesRemote Sensing, 2018
Aerosols can absorb and scatter surface solar radiation (SSR), which is called the aerosol radiative forcing effect (ARF). Great efforts have been made for the estimation of the aerosol optical depth (AOD), SSR and ARF using meteorological measurements ...

Reconciling critical zone science with ecosystem and soil science—a personal-scientist perspective

open access: yesFrontiers in Water, 2023
The critical zone has been the subject of much discussion and debate as a term in the ecosystem, soil and earth system science communities, and there is a need to reconcile how this term is used within these disciplines.

Mapping bedrock topography: a seismic refraction survey and landscape analysis in the Laramie Range, Wyoming

open access: yesFrontiers in Water, 2023
Physical, chemical, and biological processes create and maintain the critical zone (CZ). In weathered and crystalline rocks, these processes occur over 10–100 s of meters and transform bedrock into soil.

Similar vegetation‐geomorphic disturbance feedbacks shape unstable glacier forelands across mountain regions

open access: yesEcosphere, 2023
Glacier forelands are among the most rapidly changing landscapes on Earth. Stable ground is rare as geomorphic processes move sediments across large areas of glacier forelands for decades to centuries following glacier retreat.

Promoting systems thinking and pro-environmental policy support through serious games

open access: yesFrontiers in Environmental Science, 2022
We evaluated whether teaching the public about the “critical zone”–the Earth’s outer skin, critical to all life—via a digital serious game can affect adults’ systems thinking about the environment and support policies to protect the environment.
