Description:

One of the persistent challenges of Land Surface Models (LSMs) is to determine a realistic yet efficient sub-grid representation of heterogeneous landscapes. This is particularly important in emulating the fine-scale and nonlinear interactions between water, energy, and biogeochemical fluxes at the land surface. In LSMs, landscape heterogeneity can be represented using sub-grid tiling techniques, which partition macroscale grid cells (e.g., 1°) into smaller units or “tiles.” However, there is currently no formal procedure to define the number of tiles required to adequately represent the heterogeneity of hydrologic processes within a macroscale grid cell, and across spatial scales. To address these challenges, a new approach is presented to
