    Details of the retrieval algorithm are discussed in the following work:

    Gao, M., Franz, B. A., Knobelspiesse, K., Zhai, P.-W., Martins, V., Burton, S., Cairns, B., Ferrare, R., Gales, J., Hasekamp, O., Hu, Y., Ibrahim, A., McBride, B., Puthukkudy, A., Werdell, P. J., and Xu, X.: Efficient multi-angle polarimetric inversion of aerosols and ocean color powered by a deep neural network forward model, Atmos. Meas. Tech., 14, 4083–4110, https://doi.org/10.5194/amt-14-4083-2021, 2021.

    Algorithm highlights:

    • The algorithm conducts simultaneous aerosol and ocean color retrievals using multi-angle polarimetric measurements.
    • Remote sensing reflectance is derived through atmospheric correction using the retrieved aerosol properties.
    • Neural networks are used to speed up the forward model and various processing steps.
