Abstract: The Ny-Ålesund Ozone Measurements Intercomparison (NAOMI) campaignfor measurements of stratospheric ozone and temperature was conducted at thePrimary Station of the NDSC in Ny-Ålesund/Spitsbergen during Jan.-Feb. 1998.Local instrumentation (ozone and aerosol lidar, microwave radiometer RAM,ECC-type ozone sondes) was complemented with the NDSC mobile ozone lidar fromNASA/GSFC. The aim was the validation of stratospheric ozone and temperatureprofiles according to NDSC guidelines. The blind intercomparison of ozoneprofiles revealed good agreement (<5%) up to 31 km. At higher altitudes thedifferent altitude ranges and resolutions of the instruments, as well aseffects of retrieval algorithms have to be considered. Temperature data of thetwo lidar systems agreed well and revealed the stratospheric warming, whichoccurred in early February 1998. NCEP temperature analyses for Spitsbergenagreed very well with lidar data before, but not during this warming event.
