The purpose of the AQDHS-II system was to provide the Connecticut Department of Environmental Protection with improved access to, and analysis capabilities of, its air quality data. Prior to installation of AQDHS-II, punched cards and magnetic tapes served as the storage media for all air quality data. Most data requests were filled using locally developed computer programs to select and report on the needed information. The retrieval capabilities of AQDHS-II perform the search of stored air quality data, thereby eliminating the need to read in extensive card data. A second objective of the installation was to reduce the required processing by EPA and to improve the quality of the SAROAD data. The AQDHS-II editor checks for valid parameter/method/unit code combinations, and the retrieval language provides the capability to check for values that are above a certain threshold for each parameter.
