MODIS. These records link the considerable physical variability of the ocean to its intrinsic biological variability and are essential for understanding ocean processes and evaluating models. This measurement has been continually improved since the launch of CZCS in 1978. Further improvements are possible on the basis of developments in scientific understanding, technology development, and atmospheric correction (see the panel’s mission recommendation below to enhance capabilities to monitor productivity in the open ocean). The second long-term record is the terrestrial greenness record that began with the insightful
