Supporting evidence — 6 representative gaps

• Evaluation of temperature and radiation based reference evapotranspiration methods over Cross River basin Nigeria (2026) · Discover Environment · doi

  There is a need for a comprehensive evaluation of temperature and radiation-based models for estimating reference evapotranspiration. Prior work has not provided a clear understanding of the influence of climatic variables on reference evapotranspiration.

• Enhanced extremes without intensification of South America’s water cycle from 1980 to 2010 (2026) · Communications Earth & Environment · doi

  The study suggests that future research should focus on improving the representation of evapotranspiration in models. The study recommends that future research should consider the regional differentiation and complexity of the South American hydroclimate.

• Systematic overestimation of evapotranspiration over irrigated areas by an offline land surface model (2026) · Hydrology and earth system sciences · doi

  The lack of consideration of atmospheric feedback in land surface models leads to overestimation of evapotranspiration. The current land surface models do not accurately represent the effects of irrigation on local atmospheric conditions.

• Systematic overestimation of evapotranspiration over irrigated areas by an offline land surface model (2026) · Hydrology and earth system sciences · doi

  The study focuses on a specific field campaign and may not be representative of all irrigated areas. The model simulations are limited to a two-week period. The study does not account for other anthropogenic factors that may influence evapotranspiration.

• Spatial and temporal comparison of five methods for evapotranspiration in an agricultural region of China from 1961 to 2017 (2026) · Frontiers in Water · doi

  The study identifies a gap in the understanding of evapotranspiration in agricultural regions of China. The study notes that no single method is universally applicable for estimating potential evapotranspiration.

• Systematic overestimation of evapotranspiration over irrigated areas by an offline land surface model (2026) · Hydrology and earth system sciences · doi

  Further studies are needed to investigate the effects of other anthropogenic factors on evapotranspiration. The development of more realistic land surface models that account for atmospheric feedback is necessary. Additional research is required to evaluate the potential of using surface-atmosphere coupled models for other applications.
