  2. 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-2over 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. 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. 4 Science Panel Perspective Ground-Based Observations from the Tropospheric Ozone Lidar Network (TOLNet) 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. 5 Science Panel Perspective Ground-Based Observations to improve interpretation and analysis of atmospheric processes Ceilometer Sondes Have we collectively determined the ideal “validation/evaluation platform” for TEMPO? Wind Lidar UAV
