Range-corrected signal

The upper (>6 km) tropospheric ozone increases relative to July 23 possibly due to the deep convection and lightning yesterday night. It looks high humidity and heavy aerosol this morning. Lidar stops at 14:45 because of shower. Compared with the ozonesonde profile on Sat., 3-km low ozone still exists, but the 5-km low ozone layer is not on today nor last Friday's plot.
