Advances in top-of-atmosphere radiative flux estimation from the Clouds and the Earth's Radiant Energy System (CERES) satellite instrument

摘要

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.
