Juseon Bak, Xiong Liu, Robert Spurr, Kai Yang, Caroline R. Nowlan, Christopher Chan Miller, Gonzalo Gonzalez Abad, and Kelly Chance

Data sets

OMI/Aura Level 1B UV Global Geolocated Earthshine Radiances 1-orbit L2 Swath 13×24 km V003 M. Dobber https://doi.org/10.5067/Aura/OMI/DATA100

Short summary

We apply a principal component analysis (PCA)-based approach combined with lookup tables (LUTs) of corrections to accelerate the VLIDORT radiative transfer (RT) model used in the retrieval of ozone profiles from backscattered ultraviolet (UV) measurements by the Ozone Monitoring Instrument (OMI).
