CAPI

The CAPI (Cloud and Aerosol Polarization Imager) is a multi-band imager which provides radiance measurements in five bands (365-408 nm, 660-685 nm, 862-877 nm, 1360-1390 nm, 1628-1654 nm) from UV to NIR. In order to achieve more information on aerosol size, which has a significant impact on the wavelength dependence of aerosol optical properties, CAPI includes two polarization channels (660-685 nm and 1628-1654 nm) to measure the Stokes parameters.
