1 Science Panel Perspective
1 TEMPO time-of-day and day-of-week measurements can guide monitor placement (or even guide mobile platforms in near real time) Science Panel Perspective Ports, railyards, highways Newark Airport Pandora instruments have steadily matured and are moving towards a routine and systematic monitoring network via the pandonia global network and NASA pandora project; integration within other measurements networks should be done were possible, (e.g. PAMS). Need to be prepared to verify unexpected hot spots – mobile monitoring system, pandora critical. For science and application, pandora will be key measurement to fill in the sub-hourly data.

2 Science Panel Perspective
2 PANDORA NO2/H2O: captures boundary layer scales of motion – what will this mean for TEMPO validation and science? What additional assets are needed at sites? Science Panel Perspective Mesonet-NYS, Bronx NY, Windcube 100s In addition to measuring NO2 advection, Pandora is sensitive enough (1σ = 5×1013 in 10 s) to capture variations driven by large PBL eddies (up to ±1×1015 molecule cm-2 over 1-minute, or ~10%-20% of tropospheric column). Column water vapor should be a straightforward, not yet available product as well Clouds Clear-sky Eddies Bronx NY Pandora Clear-sky NO2 Advection + Large Eddies Very precise Clouds - noisy

3 Science Panel Perspective
3 Formaldehyde everywhere: how do we deploy Pandoras/use TEMPO to understand multi-generation HCHO production and its role or link to O3 and organic PM? Science Panel Perspective Westport CT coastal monitor HCHO Time Series 5.5 ppb UMD/GSFC Formaldehyde, 2-4:30 PM, 16 August 2018 Afternoon formaldehyde is between 5 ppb and 7 ppb nearly everywhere in the afternoon boundary layer on 8/16. The same is true on 8/15 (not shown in flight data) EPA data: Andrew Whitehill UMD/GSFC data: NESCAUM; R. Dickerson, X. Ren, T. Hanisco, J. St. Clair, G. Wolfe

4 Science Panel Perspective
4 Ground-Based Observations from the Tropospheric Ozone Lidar Network (TOLNet) Science Panel Perspective TEMPO 0-2 km Product Ozone Water-Land Environmental Transition Study Multiple ozone lidars at strategic deployment sites (as utilized in OWLETS 1/2 and LISTOS) Characterize chemical transport in high vertical and temporal resolution that can be mapped to the TEMPO observations (and nighttime/cloudy scenes)

5 Science Panel Perspective
5 Ground-Based Observations to improve interpretation and analysis of atmospheric processes Science Panel Perspective Ceilometer Sondes Have we collectively determined the ideal “validation/evaluation platform” for TEMPO? Wind Lidar UAV
