抄録

Tropospheric column ozone derived from Global Ozone Monitoring Experiment (GOME) measurements (GOME-O₃) was validated using operational ozonesonde measurements over Japan and compared with Tropospheric Ozone Residual (TOR) derived from Total Ozone Mapping Spectrometer and Solar Backscatter Ultraviolet measurements. The GOME-O₃ validation showed positive biases with a magnitude of less than 3 DU (∼10%) and random errors of 5-9 DU (∼15-30%) at collocated sonde stations. GOME-O₃ showed better agreement with ozonesonde measurements over Japan than TOR did. The direct comparison between GOME-O₃ and TOR showed the underestimation of TOR during winter and spring in the southern part of Japan (around 30°N).
