MOD17A2H.006: Terra Gross Primary Productivity 8-Day Global 500m [deprecated]

AI-generated Key Takeaways

• This MOD17A2H V6 dataset provides Gross Primary Productivity (GPP) data, an 8-day composite at 500m resolution, calculated using the radiation-use efficiency concept.

• This dataset has been superseded by a newer version, MODIS/061/MOD17A2H, which users are encouraged to utilize instead.

• It covers the period from 2000-02-18 to 2023-02-10 and includes bands for GPP, Net Photosynthesis (PsnNet), and quality control.

• MODIS data and products acquired through the LP DAAC have no restrictions on subsequent use, sale, or redistribution.

• Users can explore and analyze this dataset further using Google Earth Engine.

Caution: This dataset has been superseded by MODIS/061/MOD17A2H.

Description

The MOD17A2H V6 Gross Primary Productivity (GPP) product is a cumulative 8-day composite with a 500m pixel size. The product is based on the radiation-use efficiency concept and can be potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation.
