Modeling gross primary production of irrigated and rain-fed maize using MODIS imagery and CO2 flux tower data

- Integrates satellite imagery with eddy covariance flux tower measurements of maize croplands.
- Identifies MODIS vegetation indices for better delineation of maize growing season.
- Improves satellite-based light-use efficiency model for predicting GPP of maize cropland.
- Demonstrates the potential of the Vegetation Photosynthesis Model for scale-up of GPP.
