The field of hydrologic modeling, or modeling of the terrestrial hydrologic cycle, is very data intensive. Models require many inputs to define topography, geology and atmospheric conditions. Additionally, in situ observations such as streamflow rate and depth to groundwater can be used to evaluate model outputs and calibrate input parameters. There are many public organizations and research groups in the United States which produce and make freely available parts of this required data. However, the data have a wide range of spatiotemporal resolutions, file types, and methods of access. This makes finding and accessing all the data required for analysis a very time-consuming part of most hydrologic studies. The hf_hydrodata package is designed to simplify this data acquisition process by providing access to a broad array of variables, all of which have been pre-processed for consistency.
