Abstract This study presents the results of permafrost mapping in Mongolia based on TTOP (temperature‐on‐top‐of‐permafrost) approach, which were validated against situ measurements at various locations. In indicated that mean annual ground temperature (MAGT) ranged from 0.6 to 2.2°C interannually, showing greatest variability when furthest 0°C. The differences between modeled and measured MAGTs exceeded ±1°C locations where was a nonequilibrium state controlled predominantly by local...
Wetlands are critical ecosystems for supporting biodiversity and regulating climate. Over the past century, it has been degraded significantly due to both climatic human activities. In Mongolia, livestock grazing drastic impact on this ecosystem. study, we seek understand effects of soil water content (SWC) moisture by contrasting grazed non-grazed area in a wetland north-eastern Mongolia. We found that infiltration was five times lower than area. Soil higher stable near surface (5 cm depth)...
In Mongolia, greenhouse gas (GHG) and emission factors (EFs) from land-use categories including cropland, wetland, peatland, have not been estimated. The main purpose of this study was to estimate GHG EF based on field measurement data for the cropland using IPPC guideline’s Volume-2 method. determination EFs is crucial as it contributes national inventory. Study sites were selected at in (1) Khurkh river valley, (2) near Ulaanbaatar city. Fieldwork conducted during spring summer seasons...
