Characterizing Land Surface Anisotropic Reflectance over Rugged Terrain: A Review of Concepts and Recent Developments

Remote Sensing, 2018
Rugged terrain, including mountains, hills, and some high lands are typical land surfaces around the world. As a physical parameter for characterizing the anisotropic reflectance of the land surface, the importance of the bidirectional reflectance ...

Simulation and Analysis of the Topographic Effects on Snow-Free Albedo over Rugged Terrain

Remote Sensing, 2018
Topography complicates the modeling and retrieval of land surface albedo due to shadow effects and the redistribution of incident radiation. Neglecting topographic effects may lead to a significant bias when estimating land surface albedo over a single ...

Study of the Remote Sensing Model of FAPAR over Rugged Terrains [PDF]

Remote Sensing, 2016
Mountainous areas with rugged terrains are widely distributed around the world. Remotely sensed values of the fraction of absorbed photosynthetically active radiation (FAPAR) suffer from the effect of rugged terrain.

A Multi-Scale Validation Strategy for Albedo Products over Rugged Terrain and Preliminary Application in Heihe River Basin, China

Remote Sensing, 2018
The issue for the validation of land surface remote sensing albedo products over rugged terrain is the scale effects between the reference albedo measurements and coarse scale albedo products, which is caused by the complex topography.

Study on the Effect of Shortwave Radiation in Land Surface Temperature Downscaling over Rugged Terrain

Remote Sensing
Land surface temperature (LST) is an important parameter in the surface system with drastic variation in spatial and temporal domains. The protection of the ecological environment in mountainous areas and the monitoring of natural disasters require the ...

Estimating daily surface downward shortwave radiation over rugged terrain without bright surface at 30 m on clear-sky days using CERES data

International Journal of Digital Earth, 2023
In this study, the authors propose a model, called the Daily Downward Shortwave Radiation Random Forest Model over Rugged Terrain (DSRMT), to accurately calculate the downward shortwave radiation over a terrain without bright surface on clear days at a ...

Rugged terrain and rigid hierarchy

Current Research in Ecological and Social Psychology
Human societies differ markedly in their endorsement of hierarchical authority, ranging from strict obedience to powerful leaders and militaries to more decentralized and egalitarian governance.

Wolverines use spatial memory to plan efficient routes through rugged terrain [PDF]

Movement Ecology
Background To navigate, animals balance nearby perceptual cues, random search, and memory. Isolating the role of memory, however, remains difficult. Methods Here, we use a mechanistic movement model to do so, simulating animals responding solely to local
