Di Noia, A., O.P. Hasekamp, L. Wu, B. van Diedenhoven, B. Cairns, and J.E. Yorks, 2017: Combined neural network/Phillips-Tikhonov approach to aerosol retrievals over land from the NASA Research Scanning Polarimeter. Atmos. Meas. Tech., 10, 4235-4252, doi:10.5194/amt-10-4235-2017.

In this paper, an algorithm for the retrieval of aerosol and land surface properties from airborne spectropolarimetric measurements — combining neural networks and an iterative scheme based on Phillips-Tikhonov regularization — is described. The algorithm — which is an extension of a scheme previously designed for ground-based retrievals — is applied to measurements from the Research Scanning Polarimeter (RSP) on board the NASA ER-2 aircraft. A neural network, trained on a large data set of synthetic measurements, is applied to perform aerosol retrievals from real RSP data, and the neural network retrievals are subsequently used as a first guess for the Phillips-Tikhonov retrieval. The resulting algorithm appears capable of accurately retrieving aerosol optical thickness, fine-mode effective radius and aerosol layer height from RSP data. Among the advantages of using a neural network as initial guess for an iterative algorithm are a decrease in processing time and an increase in the number of converging retrievals.
