CCOS Field Operations Plan Version 2: 5/31/00 5.0 DATA MANAGEMENT AND VALIDATION The CCOS database will be compiled, documented, evaluated, and distributed by the Planning and Technical Support Division (PTSD) of the Air Resources Board (ARB). Common data management and validation conventions need to be assembled in a consistent and efficient manner. These conventions are described in this section. Greg O’Brien of the ARB will serve as the CCOS data manager. He will be responsible for establishing and maintaining computerbased data archives and managing the overall data storage and Level 1A-1B validation activities. The data manager will interact with the field manager and the program management and provide feedback to them concerning the status of unresolved data management problems and potential for resolution. Liz Niccum of T&B Systems will assist the CCOS data manager with data compilation and formatting. Eric Fujita of the Desert Research Institute will assist with Level 2 data validation. This draft version will be updated with more specific conventions and reporting structures after CCOS measurement investigators have provided their suggestions and recommendations. To the greatest extent possible, CCOS field data structures, processing, validation, and delivery procedures will be consistent with those being established for the CRPAQS (Watson et al., 1998). 5.1 Data Specifications Data management conventions and methods for CCOS and CRPAQS build on experience from and development supported by the 1990 San Joaquin Valley Air Quality Study (SJVAQS) (Blumenthal et al., 1993), the 1995 Integrated Monitoring Study (IMS-95) (Solomon and Magliano, 1997), and the 1997 Southern California Oxidant Study (SCOS-97) (Fujita et al., 1997). The following specifications are maintained by the data manager and are to be made available to all project participants via the Internet: • Monitoring Sites: Each site location for CCOS measurements is identified with a unique alphanumeric site ID accompanied by its name, address, coordinates, elevation, primary operator, and a summary of measurements taken at the site. The field manager with a Global Positioning System (GPS), pressure-based altimeter, and topographical maps verify the coordinates and elevations of each site. Immediate surroundings are recorded with a digital camera of the area surrounding the site to be displayed on the CCAQS web site. • Instruments: The make, model and serial number of instruments used to acquire measurements at each site is recorded with its threshold, range, expected accuracy and precision. • Parameters: Each observed parameter is assigned a unique code that is accompanied by its definition, units, averaging time, applicable temperature and pressure adjustments, and data reporting format. • Data validation flags: Flags specific to each measurement investigator are translated into a common set of validation flags that are carried with each data point. These are listed in Section 5.3 Chapter 5: DATA MANAGEMENT 5-1
