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. As OCO-2 is capable of providing SIF and XCO 2 products with identical spatial and temporal scales, the SIF-CO 2-GPP linear model would be implemented conveniently to monitor GPP using remotely sensed data.
