Summary, Etc.
aAn intercomparison of thirteen ultraviolet (UV) spectroradiometers and eight filter radiometers was arranged in the autumn of 1993 at the Observatory of Izaña (INM) on the island of Tenerife, Spain. The experiment, named NOGIC-93, was arranged by the Nordic Ozone Group (NOG) and joined by other nations, too. The purpose of the experiment was to gain information on the comparability of the ozone and ultraviolet measurements currently made in different countries. The intercomparison consisted of spectral measurements of laboratory lamps, laboratory equipment tests, spectrtal as well as moderate and broadband measurements in natural sunlight, total ozone column determinations, ozone soundings and experiments with radiative transfer models. The methods and the results of the intercomparison are described and suggestions for future wok are presented in the ten independent papers of this report. The main results of NOGIC-93 are the following: The agreement between the standard ozone instruments was generally excellent.; The secondary UV lamp standards were able to transfer a calibration within ±3% in most cases.; Most spectroradiometer UV calibrations agreed in laboratory conditions to within ±4 to 7%.; Deviations in measuring the electric current caused an uncertainty of ±1% in lamp irradiance.; The outdoor spectral messurements agreed at least within ±15% at wavelengths longer than 310 nm but deviated more at shorter wavelengths.; The integrated outdoor dose rates of most of the spectroradiometers generally agreed within ±10% and those of the other instruments within ±15%.; The consistency of the UV measurements could be increased by the use of a travelling lamp unit.; The radiative transfer model tested responded logically to changes in its parameters and yielded useful information on the behaviour of radiation in the atmosphere. On the whole the results can be considered promising at this stage, and they will be used in directing our future resources towards making Nordic UV and ozzone measurements comparable and keeping them so.04 Ultr
