| Summary: | This Modeling Archive is in support of a NGEE Arctic publication in review “ Drying of tundra landscapes will limit subsidence-induced acceleration of permafrost thaw ”. The study used a cryohydrology model to assess the potential risk of abrupt permafrost thaw triggered by melting ground ice, a key open question associated with permafrost response to a warming Arctic. The spatially resolved simulations are for a small catchment 465 ice-wedge polygons in polygonal tundra near Utqiaġvik, Alaska in the high-emissions RCP8.5 climate scenario. The simulations are compared to runoff, evapotranspiration and subsidence in the current climate and agree well. The study used the ATS code configured as an intermediate-scale cryohydrology model (Advanced Terrestrial Simulator, Version ngee_ism_v2 https://github.com/amanzi/amanzi/releases/tag/ngee_ism_v2). The archive includes input files for spinup (1985 to 2005) and projections (2006 to 2100 – the manuscript reports 2006 to 2098). Three of the projections include the ... |
