Abstract: An important challenge for Earth System Models (ESMs) is to accurately represent land surface and subsurface processes and their complex interactions in a warming climate. This is true for all regions of the world, but it is especially important for high-latitude Arctic ecosystems which are projected to warm at a rate twice that of the global avera ... [more]
