Assessing Net Primary Production from Space

Terrestrial Net Primary Production (NPP) quantifies the amount of atmospheric carbon fixed by plants and accumulated as biomass. The Terra/MODIS NPP product (MOD17A2) measures overall plant growth rates over an area for an 8-day period, which can be used to quantify the rate of global plant growth.

Fall Comes to North America

A comparison between the MODIS 8-day NPP data product shows the seasonal transition of plant growth rates of high (green/blue) to low (red/dark red) from late September to early October over North America. This highlights changes in plant productivity over North America due to the onset of fall.
