The tropospheric ozone increases a little bit compared to 10/21 lidar data. No ceiloemter data. The ozonesonde profile is taken on yesterday, Saturday. The 2-5 km profile is lost. The low ozone in the PBL shown on sonde profile is probably due to the cloudy sky (low clouds) before evening. Compared to yesterday, today's PBL ozone increase about 10 ppbv.
