Ecosystem Net Primary Production Responses to Changes in Precipitation Using an Annual Integrated MODIS EVI
… data as surrogate for ANPP was assessed. To use EVI as a proxy for ANPP we extracted the satellite data from areas with uniform vegetation in a 2x2 km area for the multi-site approach.In the multi-site analysis in the United States our results showed a strong exponential relationship between …
