OCO-2 collects a single, narrow slice of data cutting through a few cities on each orbit, but OCO-3 will target and record SIF at almost every major midlatitude and tropical city. The measurements may prove helpful to urban planners in using their water resources wisely, as well as to biologists in understanding the effects of heat stress on Oct 12, 2017 · OCO-2 data show that in the first few months of the 2015-16 El Niño, the rate of carbon dioxide released from the tropical Pacific to the atmosphere decreased by 26 to 54 percent. That translates to a short-term reduction of 0.4 to 0.5 parts per million in atmospheric concentration, or close to 0.1 percent of total atmospheric carbon dioxide. OCO-2 will enable measurements within a narrow swath with sufficient accuracy for 5km x 5km spatial scales—an unprecedented resolution for SIF measurements from space. The measurement technique itself is also robust against occurrences of atmospheric aerosols and thin clouds, which typically affect purely optical-based remote sensing techniques.
