Short summary
We have described an approach to estimating the background concentration level of a species, such as methane, in the atmosphere from an analysis of the measured data provided by the National Physical Laboratory's differential absorption lidar (DIAL) system. The estimation of the background level supports the mapping of pollutant concentrations and the determination of emission fluxes. Results for data provided by a field measurement are presented, and ideas for future work are discussed.
