The Joint Research Project "Traceability for atmospheric total columne ozone" aims to significantly enhance the reliability total ozone columne measured at the Earth surface with Dobson instruments, Brewer-Spectroradiometer and Array-Spectroradiometer.

New methods of observation (techniques, instruments and software) are developed to provide traceable total ozone columne measurements with an uncertainty of less than 1%.

The dissemination of the improved ozone traceability and the developed tools and methods will occur by a large field intercomparison of spectroradiometers organised at the end of the project at Teneriffe Island, Spain.
