AI-generated Key Takeaways
-
The MODIS Net Primary Production (NPP) CONUS dataset provides estimates of net primary production for the conterminous United States.
-
NPP represents the carbon captured by plants after accounting for respiration losses.
-
This dataset uses the MOD17 algorithm, MODIS Surface Reflectance, gridMET, and the National Land Cover Database for calculation.
-
The dataset is available annually from 2001 to 2019 with a pixel size of 250 meters.

Description
The MODIS Net Primary Production (NPP) CONUS dataset estimates NPP using MODIS Surface Reflectance for CONUS. NPP is the amount of carbon captured by plants in an ecosystem, after accounting for losses due to respiration. NPP is calculated using the MOD17 algorithm (see MOD17 User Guide) with MODIS Surface Reflectance, gridMET, and the National Land Cover Database.
