Abstract
This study introduces new CERES Angular Distribution Models (ADMs) for estimating shortwave, longwave and window top-of-atmosphere (TOA) radiative fluxes from broadband radiance measurements. By combining CERES measurements with narrowband, high-resolution imager measurements, up to a factor 4 improvement in TOA flux accuracy is achieved compared to TOA flux estimates from previous experiments, such as ERBE.
