Cloud Camera is not a separate instrument, rather it is used to help detect clouds in the APS nadir pixel.

Cloud Camera Research

The cloud camera is a high-spatial-resolution two-band radiometer intended to facilitate the identification of cloud-contaminated APS pixels and to determine the fraction of the pixel area occupied by clouds. Over ocean, the cloud camera will also be used to determine aerosol load and fine mode fraction over a wider swath based on the aerosol microphysical model determined from APS measurements for the nadir pixles.

Cloud Camera Data

The analysis of cloud camera data to provide cross track coverage over a finite swath of aerosol load and fine mode fraction over the open ocean provides a back up to what is planned with APS and MODIS-Aqua in the event that MODIS data are not available.
