“…While remote sensing can be effective for estimating regional ET via estimates of NDVI, local effects and the effects of specific plant morphology may necessitate some proximal sensing as well. For example, the turbulent structure of air over a vineyard, which is strongly influenced by the geometry of the underlying canopy, may not be accurately modeled by remote sensing alone [68].…”

More than half of global water use can be attributed to crop irrigation, and as the human population grows, so will the water requirements of agriculture. Improved irrigation will be critical to mitigating the impact of increased requirements. An ideal irrigation system is informed by measurements of water demand—a combination of water use and water status signals—and delivers water to plants based on this demand. In this review, examples of methods for monitoring water status are reviewed, along with details on stem and trunk water potential measurements. Then, methods for monitoring evapotranspiration (ET), or water use, are described. These methods are broken into coarse- and fine-scale categories, with a 10 m spatial resolution threshold between them. Fourteen crop ET technologies are presented, including examples of a successful estimation of ET in research and field settings, as well as limitations. The focus then shifts to water distribution technologies, with an emphasis on the challenges associated with the development of systems that achieve dynamic single plant resolution. Some attention is given to the process of choosing ET and water status sensing methods as well as water delivery system design given site characteristics and agronomic goals. This review concludes with a short discussion on the future directions of ET research and the importance of translating findings into useful tools for growers.

“…Based on the analysis, irrigation and other management practices likely tied to grape yield and quality targets played a key role in the differences observed in seasonal water use. Also evaluating fluxes in the vineyards, Alfieri et al (2022) used a profile of sonic anemometers above the vine canopy to describe characteristics of the vertical structure of turbulence. They found that this differed significantly from other cropping systems because of the wide row spacing and non-uniform distribution of vine biomass concentrated in the upper part of the canopy.…”

This second special issue of the Grape Remote sensing Atmospheric Profile and Evapotranspiration eXperiment (GRAPEX) further advances and expands upon the initial research findings of the first GRAPEX special issue on the measurement and remote sensing of vine water use and stress. This is a highly collaborative and interdisciplinary experiment, which involves USDA-ARS scientists, industry, and university researchers. The large scope of this research has allowed the development of new measurement and remote sensing tools and techniques to quantify vine evapotranspiration, moisture status, and stress, with the ultimate goal of improving irrigation management in California vineyards.
