NASA's Orbital Carbon Observing Satellite OCO-3, launched this month, will monitor global plant fluorescence

Previously, OCO-2 had the ability to monitor plant carbon uptake levels by measuring the weak fluorescence produced by chlorophyll during photosynthesis. The OCO-3 will further expand the chlorophyll fluorescence monitoring capabilities of the carbon Detection Satellite Network. OCO-3 will be attached outside the International Space Station and in orbit at 52 °S / N. SIF data will be collected more intensively than OCO-2 (because OCO-2 is in polar orbit), and OCO-3, which is on board the ISS International Space Station in instrumental form, can greatly expand OCO-3 's database collection capabilities. At the same time, the satellite can orbit the Earth in the orbit of the space station, each orbit can make SIF observations at any point at different times, and the SIF level of the point can be observed during the one-day cycle from dawn to night.
