Abstract

The LIDPORT V2PLUS radiative transfer package is designed for simulation and retrieval applications for nadir viewing remote sensing instruments such as GOME, GOME-2, SCIAMACHY, OMI and MODIS. The package is based on the LIDORT family of linearized discrete ordinate models, and it will deliver earthshine radiances, analytic profile, total column and surface property Jacobians. LIDORT V2PLUS includes a quasi-exact single scatter computation for all solar beams and the line of sight direction in a curved spherical-shell refracting atmosphere, and a full treatment of the diffuse radiation field in the pseudo-spherical approximation at all points along the line-of-sight. We give examples of radiances and O₃ air mass factors at 325 nm, and Jacobians for O₃ total column and profiles and for surface albedos, with particular emphasis on the wide-angle spherically-corrected viewing mode. We also look at the effect of horizontal inhomogeneity caused by varying surface properties along the line of sight.
