Effects of Seasonal Rainfall Characteristics on the Hydrothermal State of Permafrost Active Layer in the Central Qinghai-Xizang (Tibet) Plateau

open access: yesGaoyuan qixiang, 2023
Rainfall can cause significant changes in the hydrothermal state within the active layer of the permafrost regions, and the rainfall in the Qinghai-Xizang (Tibet) Plateau has obvious seasonal characteristics.In order to analyze the effects of seasonal ...

Estimating Ground Heat Flux from Net Radiation

open access: yesAtmosphere, 2023
Ground heat flux may play an important role in surface energy balance. In this study we evaluate the performance of the objective hysteresis model (OHM) for estimating ground heat flux from net radiation and compare it with the linear regression model. The experimental sites include residential roofs (concrete), campus grassland, agricultural grassland,
