The report summarizes the quality assurance activities of the NADP/NTN Quality Assurance Manager in 1990 and 1991. The report documents the accomplishments of the cooperative agreement and makes recommendations for the future operation of the NADP/NTN network. The report summarizes the progress being made by the NADP/NTN monitoring program in implementing its quality assurance plan.
