3 Outline Instrument description. Aerosol corrections. Validation against balloon sondes. Data Conclusions.

4 Dye Laser

5 The Instrument

6 Instrument Characterization Telescope’s performance validated. PMT response function and SIN correction determined. LED test - quantified electronic system response. Established system reliability. Mini receiver installed. LICEL (analog/photon counting) units replaced MCS boards (photon counting).

10 Typical statistical errors for day and nighttime ozone retrievals on the high and low altitude channels

11 Validation of DIAL ozone using balloon sondes (8AM) All sondes are launched at 1pm except one at 8am. Low channel works a little better than high channel. High channel has a oscillation above 6. 285 laser doesn’t have power. High statistical error and SIB error at 7-8 km relatively.

12 The mean and standard deviation of the ozone retrieval in last slide.

15 Oct. 5, 2008 Nighttime Ozone Enhancement Similar aerosol and O3 time-height structures suggest a same pollutant source.

16 8-hour peak Air Quality Index for ozone at Mississippi/Alabama region in October 2008 This was Sat.!

17 Horizontal Transport 24-hr Backtrajectories at 500, 1500 and 4000m for the nighttime ozone enhancement event observed in Huntsville on Oct. 5, 2008.

20 Conclusions RAPCD DIAL instrument is retrieving excellent lower tropospheric data. Retrievals with aerosol correction have a verified accurate of 5-20% between 1-8 km. 24-hr 10-min curtain plots shows many interesting trop O 3 features in time and space.
