  2. Where is TMF? Here!34.4N117.7W2285 m a.s.l.

  3. Recap Tropo O3 lidar at JPL-TMF Emitter: • Quadrupled Nd:YAG laser  two 266 nm 1.5 W each, Raman-shifted by H2 and D2 cells • Two beam expanders (x5), 2 computer-controlled transmitter mirrors (for auto alignment) Receiver: • One 91-cm diameter telescope, coupled with 2 bundled optical fibers for High-intensity(289/299 nm) • Two 7 cm diameter telescopes for low-intensity pair of channels (289/299 nm) • NEW: Improved STNR since September 2017 (back to early 2000s STNR) • NEW: 4 cm diameter telescope with dichroic plate for new near-surface pair 266/289 nmSee Fernando’s presentation tomorrow • 4+2 Licel transient recorders (AD+PC) • NEW: Data Acquisition Program, and data format (hdf-5)

DIAL (O3, Temper, Aer) Nominal (but only 1 excimer) Nominal Nominal Nominal (but aging) 1988-present 1999-present 2005-present 1994-present Non-NDACC Status Dates PTU radiosondes Ozonesondes Frost-point sondes Surface PTU Surface ozone Ceilometer (Vaisala) Nominal Rare launches No launch past 3 years Nominal Nominal (but need re-calibration) Nominal (part of OCTL Project) 2006-present 2006-present 2007-present 2012-present 2013-present 2015-present Non-NDACC, non-JPL Status Dates GPS-met total column water Nominal but data flowdisrupted due to changesin management 2004-present

  5. Example 1 (nighttime) JPL lidars@TMFblue, z<15 km = tropo. O3 DIALgreen = strato. O3 DIAL Blue, z>15 km: Hybrid DIAL:1 strato.channel 1 tropo.channel + Tropo O3 lidar: Good coverageup to 15 km

  6. Current TMF Lidar Group personnel Thierry Leblanc (PI) Patrick Wang (Technologist) Mark Brewer (Research Assistant) (also, Darryl Koon, Technologist, for Mauna Loa lidar) New Caltech Postdoc: Fernando Chouza Arrived August 15, 2017 First year funded by TOLNet No TOLNet funds received for his second year, so far… ????

  7. Tropo O3 Lidar Operations Operations for NDACC and TOLNet: • Nighttime: 2 hours per night, 4 nights per week, year-round  200 profiles per year • Sampling 5 min x 7.5 m, degraded to 1 or 2 hours x 30-m after data processing • Normal vertical range: 3.5 km – 27 km • NEW vertical range, with near-surface pair:2.4 km – 27 km a.s.l. (2.4 km a.s.l. is 120 m above ground) • NEW: Daytime since January, 1 hour-long, around 1 pm local time, for TROPOMI validation Data Status: Routine 2016-2018: 300+ profiles, nighttime TROPOMI validation 2018: 55+ profiles, daytime  ALL DATA UP TO APRIL 14, 2018 currently archivedat TOLNet and NDACC

  8. Other (non-routine)TOLNet Activities at TMF Sept. 2017: Implementation and validation of NDACC-standardized uncertainty budgets into TOLNet in-house data processing chains ü • AMOLITE • LMOL • TMT • TOPAZ • TROPOZ • UAH ü ü û ü û Sept. 2017 – Apr. 2018:SCOOP paper continued (see afternoon presentation) Sept. 2017 – Jan. 2018:New Data Acquisition Software Sept. 2017 – Jan. 2018:Instrument Automation Fernando ChouzaPresentation Tuesday Jan. 2018 – Apr. 2018:New near-ground channels(down to 120-m) THANK YOU
