Abstract:

Atmospheric retrieval is the extraction of atmospheric data from spectral radiance, as observed at a remote sensor. In particular, consider the retrieval of temperature and humidity profiles, and aerosol size distribution and the scattering refractive index from long-wave infrared and solar radiance spectra, respectively. The application of retrieval, in this report, primarily involves inversion of a radiative transfer equation RTE. However, due to the ill-posed nature of the problem and the inherent errors involved, such inversions are non-trivial. This report presents a combined, generalised approach to retrieval via statistical inversion, which is derived in detail for the atmospheric parameters mentioned above.
