The radiometric response of sensors change with time, and must be updated during the mission life. For example, Orbiting Carbon Observatory (OCO) requires 5% radiometric uncertainty in order to meet its XCO2 retrieval uncertainty of 1 ppm. Vicarious calibration provides this, but for sensors that view off-nadir, such as OCO, a necessary input is a model of the test site bi-directional reflectance factor (BRF).. Dongdong Wang, .
