Data Quality

The WOUDC data are subject to the Global Atmosphere Watch quality assurance system and the oversight of the Scientific Advisory Groups on ozone and solar ultraviolet radiation.

Global Atmosphere Watch

The primary objectives of the GAW quality assurance system are to ensure that the data in the World Data Centres are consistent, of known and adequate quality, supported by comprehensive metadata, and sufficiently complete to describe global atmospheric states with respect to spatial and temporal distribution.

Scientific Advisory Groups

The SAG on ozone and solar ultraviolet radiation establish data quality objectives and standard operating procedures outlining measurement methods and procedures.251

The SAG ensure that all data produced by the system conform to international standards, via the following calibration centres:
