MYD17A3HGF.061: Aqua Net Primary Production Gap-Filled Yearly Global 500m

  • The MODIS/061/MYD17A3HGF V6.1 product provides annual Gross and Net Primary Productivity (GPP and NPP) data at a 500m resolution.

  • NPP is calculated from the sum of 8-day Net Photosynthesis (PSN) values, derived from GPP minus Maintenance Respiration (MR).

  • The dataset covers the period from 2001-01-01 to 2023-01-01 and is provided by NASA LP DAAC at the USGS EROS Center.

  • Data is freely available for use, sale, and redistribution with proper citation.

  • The dataset can be accessed and analyzed using Google Earth Engine.

Description

The MYD17A3HGF V6.1 product provides information about annual Gross and Net Primary Productivity (GPP and NPP) at 500m pixel resolution. Annual NPP is derived from the sum of all 8-day Net Photosynthesis(PSN) products (MYD17A2H) from the given year. The PSN value is the difference of the Gross Primary Productivity (GPP) and the Maintenance Respiration (MR) (GPP-MR).
