2.0 GROUP B: Data Generation and Acquisition
This section addresses all aspects of data acquisition to ensure that appropriate methods of data
collection, data handling, and QC activities are being followed.
2.1 B1 – Data Collection Design
The NADP Site Survey Program is an external QA and maintenance function of sites within the
three networks of the NADP. The design, location, acceptance, and operation of the sites within
the networks are the responsibility of the NADP PO and subcommittees.
The NADP Site Survey Program is designed to test and assess each of the measurement and
sample collection devices at all of the sites in the NADP. The locations of the sites can be found
at www.nadp.sws.uiuc.edu.
The schedule of site surveys will be established to enable each site in the NADP to be surveyed
once approximately every three years. The current Site Survey Schedule can be found at
FTP://67.192.214.230.
The sites are comprised of instruments and equipment that have been approved by the NADP PO
and subcommittees. Table 2 summarizes the instruments and equipment operated by the networks
of the NADP and those used during the survey procedures to assess the operation of the
equipment.
