7 September 2010 Aerosol Polarimeter Sensor (APS) contamination control requirements and implementation
Author Affiliations +
The Aerosol Polarimetery Sensor (APS) is a nadir viewing, along-track observing, continuously operating electro-optical polarimeter designed to measure earth and atmosphere scene spectral radiance in the visible (VIS) to short wave infrared (SWIR) spectrum from an altitude of 705 km to permit collection of data for retrieval of operational Environmental Data Records (EDRs). APS performance can be degraded due to light scatter, transmission, or reflectance changes caused by contamination. Molecular films can cause scattering as well as spectrally selective absorption and reflectance degradation. At short wavelengths, the molecular films may also create polarization changes. Raytheon developed and implemented a contamination control program that ensured the APS sensor complied with cleanliness requirements. Representative cleanliness monitoring results and lessons learned from the sensor integrated and tested at Space and Airborne Systems El Segundo and Santa Barbara Remote Sensing (SBRS) are also presented.
