Estimating thawing depths and mean annual ground temperatures in the Khuvsgul region of Mongolia

Abstract: Permafrost is an important component in the ecosystem and plays a key role in soil regime characteristics in high-altitude regions. Thawing depths and mean annual ground temperatures are the main parameters to conduct research on permafrost. Here we present the results of different modeling approaches for estimating thawing depths and mean annual ground temperatures in the Khuvsgul region of Mongolia. The aim of this study was to analyze the modeling approaches and determine what model best simulates the diffe… Show more

“…Inferring the active layer properties from air temperature is a difficult exercise as it depends on local thermal properties, snow cover, soil layering and water availability [ Smith and Riseborough , ]. The ALT is usually measured “in situ” by probing [ Zorigt et al , ; Cheng and Wu , ] or through geophysical investigations such as temperature sensors or ground penetrating radar [ Hinkel et al , ; Wu et al , ]. Estimating ALT variations over broad regions can be done by interpolating probe data using vegetation index maps compiled from remotely sensed data [ Nelson et al , ], ground resistivity [ Pastick et al , ], or relative elevation [ Gangodagamage et al , ].…”

“…The Stefan equation has few parameters, a simple form, and a reliable simulation effect. It is one of the commonly used algorithms in the study of glaciology and cryopedology (Nelson et al, 1997;Zorigt et al, 2016;Bai et al, 2018). Klene (2005) considered the thermal performance and topography of the thawing index, soil moisture, and land cover characteristics of a study area, used the Stefan equation to calculate the spatial variation characteristics of ALT in the Arctic urbanization area, and developed it into a regional probability stochastic model of ALT.…”

“…For this type of deformation monitoring, it needs not only to meet the basic requirements of large-scale regional monitoring, but also to have enough accuracy and fast cycle to accurately and timely find the key areas that may have disasters. With precise levelling and GPS technology, accurate settlement data of several fixed positions could be achieved and the results could remain high reliabilities (Hinkel et al, 2001;Wu et al, 2010;Zorigt et al, 2016). However, levelling and GPS survey are all point-based with low point density, high observation cost and long repeated observation period.…”
