| 520 | _ | _ | |a Multiple limb sounder measurements of the same atmospheric region taken from different directions can be combined in a 3D tomographic retrieval. Mathematically, this is a computationally expensive inverse modelling problem. It typically requires an introduction of some general knowledge of the atmosphere (regularisation) due to its underdetermined nature.This paper introduces a consistent, physically motivated (no ad-hoc unphysical parameters) variant of the Tikhonov regularisation scheme based on spatial derivatives of first and second order. As shown by a case study with synthetic data, this scheme, combined with irregular grid retrieval methods, improves both upon the quality and the computational cost of 3D tomography, while eliminating grid dependence and the need to tune parameters for each use case. The few physical parameters required can be derived from in situ measurements and model data. An efficient Monte Carlo technique was adopted for retrieval accuracy estimation. |
