【 摘 要 】

Following the 38th Annual European Meeting on Atmospheric Studies byOptical Methods in Siuntio in Finland, an intercalibration workshopfor optical low light calibration sources was held in Sodankylä,Finland.The main purpose of this workshop was to provide acomparable scale for absolute measurements of aurora and airglow.All sources brought to the intercalibration workshop were comparedto the Fritz Peak reference source using the Lindau CalibrationPhotometer built by Wilhelm Barke and Hans Lauche in 1984. Theresults were compared to several earlier intercalibration workshops.It was found that most sources were fairly stable over time, witherrors in the range of 5–25%.To further validate the results,two sources were also intercalibrated at UNIS, Longyearbyen,Svalbard. Preliminary analysis indicates agreement with theintercalibration in Sodankylä within about 15–25%.
