TopoWx ("Topography Weather," Oyler et al. 2015, Oyler et al. 2016) is a gridded dataset of daily minimum and maximum air temperature for the conterminous U.S. at 800-m resolution. The values are interpolations based on elevation variables and MODIS land skin temperature, which are designed to capture locally relevant topoclimatic spatial patterns as well as regional climate variability and trends. The TopoWx product was produced by the Numerical Terradynamics Lab at the University of Montana with funding from the DOI North Central Climate Science Center (NC CSC). TopoWx is publicly available and being used by stakeholders. The NC CSC is actively utilizing these data in their ongoing analysis of understanding the impacts of a changing climate on species and habitats of concern to DOI.
