GeoAI Applications to Predict Field Scale Actual Evapotranspiration
October 23, 2024 11:00 am (Central Time)
Abstract
In water-scarce regions, effective agricultural water management hinges on accurate evapotranspiration (ETa) estimation. Traditional methods and satellite products often fall short due to spatial biases and limited ground representation. In this talk, we will present our efforts to develop a data-driven model that leverages machine learning techniques to predict daily reference evapotranspiration at a finer spatial resolution. This approach aims to optimize water use in semi-arid regions, ensuring sustainable crop production. Join us for a detailed exploration of the model development process, its applications, and implications for agricultural water management.

Laurel DiSera
Columbia University
Laurel is interested in understanding how climate impacts society, especially in Latin America. As a Climate and Society scientist, Laurel desires to learn more about the impacts of different climate phenomena occurring at different timescales, also known as cross-timescale interference, and how these impacts affect livelihoods at a local level. Laurel conducts her research at the International Research Institute for Climate and Society, part of the Climate School at Columbia. In her previous work during her Master's and at the IRI, Laurel spent time in Guatemala working to increase climate knowledge throughout the country, specifically with locals in rural regions. Additionally, Laurel has focused on how Aedes-borne diseases in the Americas and worldwide are impacted by climate and how improving the skill of Subseasonal to Seasonal (S2S) forecasts can be used by decision makers to improve the livelihoods of their constituents.
