[en] This report documents key aspects of the Atmospheric Radiation Measurement (ARM) Program's data quality assurance program. Processes described include data archival, display, and distribution, data stream reprocessing, and future directions in ARM data quality checking. A comprehensive, end-to-end data quality assurance program, from instrument siting, to calibration and maintenance, through data quality control and well-documented dissemination, is essential for producing a high-quality research data set. The processes developed over the past 15 years by the ARM Program offer a possible framework for use by other instrumentation-diverse networks, and are offered here to highlight the myriad aspects that go into producing such a data set.
