Quality assurance in TFS for inorganic compounds

A quality assurance program for the three main field experiments in TFS covering O-3, NO, NOx, NOy, CO, O-3 LIDARs and meteorological parameters was designed and executed. The results are presented and problems encountered during the execution phase are discussed. The need for and the benefit of independent quality assurance activities is demonstrated and documented in detailed meta data files that are part of the final data set
