24th Conference on IIPS


Interactive quality assurance practices

Karsten Shein, NOAA/NESDIS/NCDC, Asheville, NC

Historically, most post-observation quality assurance (QA) of federally-collected climate data has been administered by NOAA's National Climatic Data Center (NCDC). These efforts have achieved great success appropriately identifying the validity of over 95% of in-situ data ingested by NCDC. However, growing interest from the atmospheric science community in ensuring the utmost quality of the historical climate record has led NCDC to both develop and participate in a number of interactive QA practices. These practices include the development of the Health of the Network (HoN) tool and the use of the Datzilla error reporting and tracking tool. These tools and their use ensure that stakeholders such as NOAA field personnel, regional climate centers and state climatologists are able to more readily detect observational irregularities, communicate more effectively with NCDC regarding possible errors they identify in the climate data archive, and track quality flags and data value estimates set by NCDC's quality control processes.
