MISR Rationale for Nine Cameras/Four Bands
This diagram illustrates the roles each of the 9 cameras and 4 color bands play in MISR science. Each MISR camera corresponds to one labeled column. In the lower part of the figure, colored boxes indicate that the corresponding camera is used for the science objective to the right. For example, the An camera (which looks straight down) is needed to geo-locate MISR images, and for "inter-calibration" with other instruments. The terms "Albedo" and "BRDF" refer to ways that a surface reflects light.
Each of the MISR color bands corresponds to one of the labeled rows in the figure. On the right side, colored boxes indicate that the corresponding color band is needed for the science objective at the top. For example, the 670 nm (red) and 865 nm (near infrared) bands are used to detect aerosols over ocean, since the ocean surface is darkest in these bands, making bright aerosols easier to see.
