How much carbon plants capture daily (MODIS plus FLUXNET)
What it measures. Daily estimates of gross primary production, that is, how much carbon plants pull from the air and capture through photosynthesis worldwide, with uncertainty estimates.
How it's made. Created by feeding MODIS surface reflectance from NASA's Terra and Aqua satellites into neural networks trained on ground-based carbon measurements from FLUXNET towers, gridded at 0.05 degrees.
How & where you'd use it. Helps scientists track how much carbon the world's plants take up over time, supporting carbon cycle and climate research.

Official description
This dataset provides global gridded daily estimates of gross primary production (GPP) and uncertainties at 0.05-degree resolution for the period 2000-03-01 to the recent past. The GPP was derived from the MODerate-resolution Imaging Spectroradiometer (MODIS) instruments on the NASA Terra and Aqua satellites using the MCD43C4v006 Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectances (NBAR) product as input to neural networks that were used to globally upscale GPP estimated from selected FLUXNET 2015 eddy covariance tower sites. Additional data will be added periodically.
