The lack of consideration of atmospheric feedback in land
Research gap analysis derived from 3 earth_science papers in our local library.
The gap
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.
Evidence profile
Sourced from the future-work section and stated research gap and limitations section of the source papers, classified as general, spanning 3 journals.

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.

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.

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.
