The condition of frozen ground bears on many aspects of northern\r\necology, climate, engineering and society. The temperature based definition of permafrost\r\nhighlights that understanding the condition of permafrost requires understanding the temperature\r\ndistribution and energy balance of the ground. Physically based numerical modeling\r\nof earth systems is a tool for understanding how past geoclimate conditions have\r\nproduced current features, and how prospective changes in forcing might manifest future\r\nchanges in landscape or climate.\r\nI have developed a numerical model to solve for a one-dimensional temperature distribution\r\nresponding to time-dependent boundary conditions. Novel features of the model are\r\na coordinate transformation which allows for a spatially mobile upper domain boundary,\r\nand a constituent mixture approach to define temperature dependent thermophysical soil\r\nproperties. The model development is guided by a desire to minimize the stringency of\r\ninput data requirements due to the sparse availability of quantitative information on soil\r\nproperties and surface conditions.\r\nA variety of model applications are demonstrated using synthetic simulations and real\r\nworld data.","language":"en"},{"key":"dc.format.extent","value":"12569944 bytes","language":null},{"key":"dc.format.mimetype","value":"application\/pdf","language":null},{"key":"dc.language.iso","value":"eng","language":"en"},{"key":"dc.publisher","value":"University of British Columbia","language":null},{"key":"dc.rights","value":"For non-commercial purposes only, such as research, private study and education.
