Summary

Understanding how different crops use water over time is essential for planning and managing water allocation, water rights, and agricultural production. The main objective of this paper is to characterize the spatiotemporal dynamics of crop water use in the Central Valley of California using Landsat-based annual actual evapotranspiration (ETa) from 2008-2018 derived from the Operational Simplified Surface Energy Balance (SSEBop) model. Crop water use for ten crops are characterized at multiple scales. The Mann-Kendall trend analysis revealed a significant increase in area cultivated with almonds and their water use, with an annual rate of change of 16,327 hectares in area and 13,488 ha-m in water use. Conversely, alfalfa showed a [...]

Purpose

This data was created to determine crop water use for major crops in the Central Valley of California for a peer-reviewed journal article in Remote Sensing. The annual total evapotranspiration data has multiple applications for hydrologists, water resource managers, and farmers. The data is meant to represent the amount of water (in millimeters) that is expressed as transpiration from vegetation and evaporation from the surrounding soil.
