• The Ny-Ålesund Ozone Measurements Intercomparison (NAOMI) campaign for measurements of stratospheric ozone and temperature was conducted at the Primary Station of the NDSC in Ny-Ålesund/Spitsbergen during January-February 1998. Local instrumentation (ozone and aerosol lidar, microwave radiometer RAM, ECC-type ozone sondes) was complemented with the NDSC mobile ozone lidar from NASA/GSFC. The aim was the validation of stratospheric ozone and temperature profiles according to NDSC guidelines. The blind intercomparison of ozone profiles revealed good agreement (<±5%) up to 31km. At higher altitudes the different altitude ranges and resolutions of the instruments, as well as effects of retrieval algorithms have to be considered. Temperature data of the two lidar systems agreed well and revealed the stratospheric warming, which occurred in early February 1998. NCEP temperature analyses for Spitsbergen agreed very well with lidar data before, but not during this warming event.
