Mississippi is the second largest annual rainfall state in the US, however, water deficit was observed between soybean crop water requirement and rainfall supply, especially in July and August during growing season. More than 60 percent of Mississippi’s soybean crop uses some form of irrigation to increase or stabilize soybean productivity. Therefore, there is a need to help farmers and producers to improve their utilization of surface water and irrigation management practices. Satellite remote sensing has been used to improve regional, near-real time estimates of crop water use in water deficit areas. In this study, we presented a satellite-based thermal remote sensing method to estimate evapotranspiration (ET) for crop in East Central Mississippi. Landsat 7 images were acquired in 2014 growing season for East Central region of Mississippi. METRIC model (Mapping Evapotranspiration at High Resolution using Internalized Calibration) was applied on the imagery to develop daily ET maps and derive crop coefficients. The procedure for quantifying ET presented in this study should be useful in other regions of the State.
