Abstract

Obtaining a high quality climatic information has been challenging for the region of Arctic Alaska. A high-resolution model-based dataset was developed specifically for the coastal region and foothills of Arctic Alaska. A dynamical downscaling approach was conducted on both a reanalysis dataset and multi-scenario global climate model output. In addition to the fine spatial resolution, long temporal coverage, and multi-scenario availability, the dataset is derived from a physically-based and dynamic model, compared to the previous, mainly statistical, downscaling products for Alaska. The historical and future climate products are currently informing North Slope hydrological models and land management.
