Gross primary productivity 2000—2024 at 30m, Bimonthly, Uncalibrated
Satellite based estimates of gross primary productivity (GPP) — the rate at which plants absorb carbon dioxide from the atmosphere through photosynthesis to produce the energy they need to grow. Uncalibrated bimonthly GPP values can be customized with regional or biome specific light use efficiency factors.
Caution: This is uncalibrated data which shows the spatial variability of GPP across the whole world for each year. This data shows all land globally and does not adjust for different types of land cover such as forests and grasslands. To see how efficiently plants grow in different areas, users need to apply a land cover (e.g., forest, grassland etc.) specific factor to the data known as maximum light use efficiency (LUEmax), which reflects how efficiently plants use sunlight to fix carbon and grow.
Because this uncalibrated GPP data does not include LUEmax adjustments, users can customize the product by inputting their own regional land cover map or applying class-specific LUEmax factors based on the literature or expert knowledge for a biome of interest (See Table 2 in the publication).
