Molecular Line Parameters & VAMDC : An atmospheric/laboratory physicist point of view

"Molecular line parameters are used to interpret observational spectra and are an integral part in the data evaluation chain. Given from the perspective of a laboratory physicist, this talk provides an overview on molecular line parameters, how they are obtained and how they are made available to the user. Taking NH3 and O3 as two example molecules, the problem of measuring and modelling line parameters using current technologies from the UV to the mid-infrared are described and associated uncertainties are discussed. We also cover availability and access of molecular line data through the database infrastructure VAMDC (http:\/\/portal.vamdc.org\/)."
