Carbon Density Change Characteristics and Driving Factors During the Natural Succession of Forests on Xinglong Mountain in the Transition Zone Between the Qinghai–Tibet and Loess Plateaus

Atmosphere
The transition zone between the Qinghai–Tibet and Loess Plateaus is an important ecological functional area and carbon (C) reservoir in China. Studying the main drivers of C density changes in forest ecosystems is crucial to enhance the C sink potential ...

Bragg scattering of surface-gravity waves by an ice shelf with rolling surface morphology

Annals of Glaciology
The propagation of elastic-flexural–gravity waves through an ice shelf is modeled using full three-dimensional elastic models that are coupled with a treatment of under-shelf sea-water flux: (i) finite-difference model (Model 1), (ii) finite-volume model

Activity Concentration of Radon, Thoron, and Their Decay Products in an Open System

Atmosphere
The article presents a model for the simulation of changes over time in the activity concentrations of radon and thoron and their progeny in an open system. The results of these simulations can be helpful in adapting the calibration process to the object
