The CLARREO mission has outlined some preliminary requirements for a space based spectrometer to measure visible to near infra-red Earth albedo with a 0.3% absolute accuracy, 0.1%/decade calibration stability and a 10km footprint size at nadir. It is well known that some Earth viewing optics undergo significant degradation at solar wavelengths when in orbit which is not directly detectable using onboard calibration sources. This makes the requirements for CLARREO very challenging, requiring the development of new instrumental concepts in order to meet the goals required. A new type of telescope system is hence proposed that uses raster scan data from the Sun as its primary calibration metric. The 10-5 attenuation necessary for Earth viewing optics to view the Sun directly is achieved using the new concept of a Solar Intensity Distributing and Convolving Optic (SIDCO), whose degradation itself is monitored to very high accuracy and precision. The proposed instrument requires no more moving parts or gimbals than those used on the long running CERES instruments. It also provides redundancy in order to continue benchmark albedo measurements even during the instruments solar calibration periods. Such redundancy also allows continual monitoring of the incoming solar spectrum.
