Evaluating effects of Dielectric Models on the surface soil moisture retrieval in the Qinghai-Tibet Plateau

Based on the measurement of L-band ground-based microwave radiometer(ELBARA-III type) in the Qinghai-Tibet Plateau and the τ-ω radiative transfer model, this research evaluated the effects of four soil dielectric models, i. e., WangSchmugge, Mironov, Dobson, and Four-phase, on the L-band microwave brightness temperature simulation and soil moisture retrieval. The results show that with the same vegetation and roughne...  (本文共15页) 阅读全文>>

Method development for estimating soil organic carbon content in an alpine region using soil moisture data

The high soil organic carbon(SOC) content in alpine meadow can significantly change soil hydrothermal properties and further affect the soil temperature and moisture as well as the surface water and energy budget. Therefore, this study first introduces a parameterization scheme to describe the effect of SOC content on soil hydraulic and thermal parameters in a land surface model(LSM), and then the SOC content is esti...  (本文共11页) 阅读全文>>

Untangling the influence of soil moisture on root pullout property of alfafa plant

Root pullout property of plants was of key importance to the soil reinforcement and the improvement of slope stability. To investigate the influence of soil moisture on root pullout resistance and failure modes in soil reinforcement process, we conducted pullout tests on alfalfa(Medicago sativa L.) roots at five levels(40, 30, 20, 10 and 6 kPa) of soil matric suction, corresponding to respectively 7.84%, 9.66%, 13.02...  (本文共10页) 阅读全文>>
