Dear CERES Team:
I currently work with a narrow-band polar-orbiting satellite (e.g. MODIS) to retrieve outgoing long-wave radiation products. To accurately evaluate the narrow-band (MODIS) and broad-band (CERES) radiation radiance relationships using atmospheric radiative transfer models, I need to download the anisotropic factors of CERES Terra/Aqua Edition4 ADMs. I also want to perform a comparative analysis to find causes of error. However, I cannot find the Anisotropic Factor Tables CERES Terra/Aqua Edition4 ADMs on the CERES project website (https://ceres.larc.nasa.gov/data/angular-distribution-models/).

Sincerely,
Li Dahui

Hi Li Dahui,

Thank you for your question. I found the following documents with tables of CERES anisotropic factors. If these don't work for you, I can contact the CERES Science Team for the anisotropic factors tables.
