Description
This is the E-DRoPS dataset that shows the evaporative source region for precipitation events into each HUC2 region of the United States at daily-timesteps from 1990-2024. A full description is available in Aerenson et al. (2026).

This data is available for public use, however considerable time and effort was put into generating it, so if this data is used in a publication, co-authorship or acknowledgment may be appropriate. Please reach out to the author at taerenso@uwyo.edu to inquire.
