A first intercomparison of JNO2 measurements by actinic flux spectroradiometry (SR) and chemical actinometry (CA) was performed in summer 1997 in Jülich, Germany. During this experiment (JCOM97) a large set of data was collected with a time resolution of ∼ 1 min, showing a high linear correlation (R = 0.998) in JNO2. Linear regression indicates a good absolute agreement with the CA being 6% higher than SR if the quantum yield recommended by NASA/JPL (1997) and recently published data of the NO2 absorption spectrum (σNO2) is used for the evaluation of the SR‐data. The influence of using previously published σNO2 data is discussed. Overall the comparison suggests that JNO2 can be measured by either CA or SR with an accuracy of better than 10%.
