Abstract Quantifying evapotranspiration (ET) is critical to accurately predict vegetation health, groundwater recharge, and streamflow generation. Hillslope aspect, the direction a hillslope faces, results in variable incoming solar radiation subsequent water use that drive ET. Previous work watersheds with single dominant type (e.g., trees) have shown equator‐facing slopes (EFS) higher ET compared pole‐facing (PFS) due evaporative demand. However, it remains unclear how differences (i.e., grasses influence partitioning between hillslopes opposing aspects. Here, we quantified root‐zone storage deficits PFS EFS contrasting types within central coastal California. Our suggest cooler oak trees has than warmer grasses, which counter previous landscapes singule type. deficit calculations indicate subsurface larger seasonal dry down EFS. This aspect difference may replenishment of dynamic storage, recharge In addition, on reduce their ability serve as hydrologic refugia for oaks during multi‐year droughts. research provides novel integration field‐based remotely‐sensed estimates required properly quantify hillslope‐scale balances. These findings emphasize importance resolving structure Earth system models, especially diverse types.
