The airborne Research Scanning Polarimeter (RSP) produces a large multi-spectral multi-angular dataset for each observation. Using machine learning techniques we developed a fast retrieval of cloud properties using the full RSP dataset. This retrieval can be used as a rapid first-guess to accelerate slower but more rigorous retrievals. We applied this to cloud and aerosol observations made during the ORACLES sub-orbital field campaign.

NPPScience,ReedEspinosa:Retrievalsusingahybridimplementa>onofDarkTargetandGRASPAerosolalgorithms

A new retrieval has been developed (DT-GRASP) combining the pixel preparation techniques of the Dark Target algorithm and the versatile inversion capabilities of GRASP. The flexibility of GRASP allows a priori assumptions to be derived from a joint retrieval with AERONET. When the tuned retrieval is applied exclusively to space-based observations from MODIS very good agreement is found with the measured aerosol optical depth (τ).
