Description
Summary:Goal of the project CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrumented Container) is to carry out regular and detailed observations of atmospheric composition (particles and gases) at cruising altitudes of passenger aircraft, i.e. at 9 - 12 km. Mercury has been measured since May 2005 by a modified Tekran instrument (Tekran-Analyzer Model 2537 A, Tekran Inc., Toronto, Canada) during monthly intercontinental flights between Europe and South and North America, Africa and Asia. Here we describe the instrument modifications, the post-flight processing of the raw Tekran signal, and the speciation experiments.
