Note: Funding Information: GroMoPo development was supported by the Consortium of Universities for the Advancement of Hydrologic Sciences Inc. (CUAHSI) through a HydroInformatics Innovation Fellowship to SZ along with assistance from Veronica Sosa‐Gonzalez and Austin Raney. Most importantly, we want to thank all the groundwater modelers who have contributed effort, energy, and understanding to creating these useful tools.
