UAV PHOTOGRAMMETRY FOR MAPPING AND MONITORING OF NORTHERN PERMAFROST LANDSCAPES
Unmanned Aerial Vehicles UAVs Mapping Arctic Disturbance Permafrost Structure from motion
2015/9/10
Northern environments are changing in response to recent climate warming, resource development, and natural disturbances. The Arctic climate has warmed by 2–3°C since the 1950’s, causing a range of cr...
Estimation of the Mean Annual Surface Temperature and Surface Frost Number Using the MODIS Land Surface Temperature Products for Mapping Permafrost in China
permafrost MAST surface frost number remote sensing MODIS, China
2013/9/2
n this paper, we propose a pragmatic scheme for estimation of MAST and surface frost number, based on the assumption that the average of maximum and minimum land surface temperature (LST) represents t...
Monitoring and modeling the infl uence of snow pack and organic soil on a permafrost active layer, Qinghai – Tibetan Plateau of China
Qinghai–Tibetan Plateau Active layer Organic soil Snow pack CoupModel
2013/9/2
As a result of global warming, the depth of the permafrost active layer on the Qinghai–Tibet Plateau (QTP) hasbeen increasing progressively during thepast few decades. The Cold and Arid Regions Enviro...
OBJECT BASED THERMOKARST LAKE CHANGE MAPPING AS PART OF THE ESA DATA USER ELEMENT (DUE) PERMAFROST
