Using High-Density Rain Gauges to Validate the Accuracy of Satellite Precipitation Products over Complex Terrains

open access: yesAtmosphere, 2020
Topography and precipitation intensity are important factors that affect the quality of satellite precipitation products (SPPs). A clear understanding of the accuracy performance of SPPs over complex terrains and its relationship with topography is ...

Visual saliency-based landslide identification using super-resolution remote sensing data

open access: yesResults in Engineering
Landslides, ubiquitous geological hazards on steep slopes, present formidable challenges in tropical regions with dense rainforest vegetation, impeding accurate mapping and risk assessment.

Soil moisture dynamics in heterogeneous tropical landscapes using active–passive Earth observations and machine learning

open access: yesSoil Advances
Accurate monitoring of soil moisture (SM) at high spatial resolution remains challenging in tropical landscapes, where interactions among soil, vegetation, and terrain drive complex hydrological dynamics. We developed a Relative Soil Moisture Index (RSMI)

Quantifying urban climate response to large-scale forcing modified by local boundary layer effects

open access: yesFrontiers in Environmental Science
Over the past two decades, the joint manifestation of global warming and rapid urbanization has significantly increased the occurrence of heatwaves and the formation of urban heat islands in temperate cities.

Visual detection based distance sampling offers efficient density estimation for distinctive low abundance tropical forest tree species in complex terrain

open access: yesForest Ecology and Management, 2012
Good density estimates for low abundance tree species are costly to achieve especially in rugged or disturbed forest landscapes. More efficient methods would be of considerable value to managers and conservationists. Here we assess a method that has been neglected in this context.

Did AI win after all?

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Algorithmic platforms are reshaping how people work and how human activity is rendered intelligible within data‐intensive systems. This paper argues that Heidegger's philosophy of technology, specifically Ge‐stell (enframing) and Poiesis (bringing‐forth), offers information science a conceptual vocabulary for understanding both algorithmic ...

Physics-Driven Trajectory Backtracking Method for Drifting Buoys Based on Uncertainty Quantification

open access: yes水下无人系统学报
High-precision trajectory backtracking technology for drifting buoys is urgently needed for maritime search and rescue and pollution source tracing, yet traditional Lagrangian models exhibit significant errors in complex marine environments.

Evaluation and Intercomparison of High-Resolution Satellite Precipitation Estimates—GPM, TRMM, and CMORPH in the Tianshan Mountain Area

open access: yesRemote Sensing, 2018
With high resolution and wide coverage, satellite precipitation products like Global Precipitation Measurement (GPM) could support hydrological/ecological research in the Tianshan Mountains, where the spatial heterogeneity of precipitation is high, but ...

Bricks, knots, and bodies: Material encounters and the affective making of masculinity

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This paper examines how creative research methods do not just capture boys' experiences of masculinity, but actively materialise them. Drawing on two arts‐based activities used in school‐based fieldwork (a mannequin‐based exercise with one participant and a Lego‐building workshop with a small peer group), the paper analyses how materials ...
