AI-generated Key Takeaways
-
The Landsat Gross Primary Production (GPP) CONUS dataset estimates Gross Primary Production (GPP) for the conterminous United States using Landsat Surface Reflectance.
-
GPP represents the amount of carbon captured by plants and is a key factor in calculating Net Primary Production (NPP).
-
The dataset utilizes the MOD17 algorithm, incorporating Landsat Surface Reflectance, gridMET data, and the National Land Cover Database for GPP calculations.
-
It provides 16-day GPP estimates at a 30-meter resolution, spanning from 1986 to 2021.
-
This dataset is in the public domain and freely available for use, requiring proper citation in any derived works.

Description
The Landsat Gross Primary Production (GPP) CONUS dataset estimates GPP using Landsat Surface Reflectance for CONUS. GPP is the amount of carbon captured by plants in an ecosystem and is an essential component in the calculations of Net Primary Production (NPP). GPP is calculated using the MOD17 algorithm (see MOD17 User Guide) with Landsat Surface Reflectance, gridMET, and the National Land Cover Database.
