Remote sounding of the atmosphere has proved to be a fruitful method of obtaining global information about the atmospheres of the earth and planets. This book treats the inverse problem of remote sounding comprehensively, and discusses a wide range of retrieval methods for extracting atmospheric parameters of interest from the quantities such as thermal emission that can be measured remotely. Inverse theory is treated in depth from an estimation-theory point of view, but practical questions are also emphasized, for example designing observing systems to obtain the maximum quantity of information, efficient numerical implementation of algorithms for processing of large quantities of data, error analysis and approaches to the validation of the resulting retrievals, The book is targeted at both graduate students and working scientists.read more

Top-down estimate of a large source of atmospheric carbon monoxide associated with fuel combustion in Asia
TL;DR: This paper used an inverse modeling methodology to find the source of carbon monoxide from fossil-fuel and biofuel combustion in Asia during 1994, which is 110-140 Tg yr−1 higher than bottom-up estimates derived using traditional inventory-based approaches.

TL;DR: This paper applied a continental-scale inverse modeling system for North America based on the GEOS-Chem model to optimize California emissions at 1/2° × 2/3° horizontal resolution using atmospheric observations from the CalNex aircraft campaign (May-June 2010) and from satellites.
