Range-corrected signal

Ozone retrievals are produced only up to 6km due to clouds at ~7km. The ozone layer at 5km was already shown on yesterday's curtain plot. This ozone layer sinks to ~3km (also the aerosol) in the evening and becomes weak. This should be related to the mixing of different air masses when the cold front passes over Huntsville.
