MODIS Net Primary Production CONUS

AI-generated Key Takeaways

• The MODIS Net Primary Production (NPP) CONUS dataset estimates the net amount of carbon captured by plants in the CONUS region, accounting for respiration losses.

• It utilizes the MOD17 algorithm, MODIS Surface Reflectance, gridMET, and the National Land Cover Database for its calculations.

• The dataset, provided by the University of Montana NTSG, covers the period from 2001 to 2019 at a 250-meter resolution.

• NPP values are expressed in kilograms of carbon per square meter and include a quality control band indicating the percentage of gap-filled NDVI values.

• This dataset is in the public domain and is free to use, with proper citation encouraged.

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.
