Meeting Agenda


A joint science meeting for the TEMPO, GeoXO ACX (Atmospheric Composition Instrument), and TOLNet programs will be held at the University of Alabama in Huntsville (UAH) from May 1-5, 2023, themed “Building the Pathway from TEMPO to GeoXO.” The joint meeting will bring together the TEMPO Science Team and Early Adopters Program along with the GeoXO and TOLNet Science Teams to facilitate the coordination and long-term planning of air quality observations over North America from Geostationary Earth Orbit, with TEMPO scheduled for launch in April 2023 and GeoXO ACX expected to launch in the early 2030s. Hourly temporal resolution of both trace gases and aerosols from the TEMPO and GeoXO ACX missions are set to significantly advance our capabilities to understand, monitor, and predict air quality, weather, and climate over the next few decades.

The meeting format will be organized into discussion sessions involving designated moderators and panelists, with topics (non-exhaustive) on TEMPO Green Paper “special” experiments, the GeoXO mission, TEMPO validation, correlative campaigns, science studies, and applications, in addition to a week-long poster session with two designated viewing times during the week. Hands-on training sessions focused on TEMPO proxy data will also be offered at the meeting. A detailed meeting agenda is available at the button link above.

Everyone, including virtual participants, is encouraged to bring a poster. UAH is providing the ability to print in house (at UAH) these posters for you, free of charge. UAH printing will include putting it on display as well.

We will accommodate everyone in both physical meeting rooms on the UAH campus and with Zoom access. There will be planned outings on Tuesday evening at Burritt Museum (with buffet dinner), on Wednesday at the Space and Rocket Center (sit-down dinner under the Saturn V rocket in the Davison Center), and a buffet lunch at the Huntsville Botanical Gardens on Thursday.

This meeting is open to individuals who are interested in the TEMPO, GeoXO ACX, and TOLNet Programs. We especially welcome students and early-career professionals to attend the meeting.

Virtual and in-person participants will have live access to all discussions including verbal and Zoom chat. Moderators will solicit and compile all slides / visualizations for the discussion sessions.

Meeting Guidance


  1. Develop a robust strategy for implementing the TEMPO “Green Paper” science experiments and coordinating and enhancing the special operation data from the TEMPO mission.
  2. Scope out a long-term plan between the TEMPO and GeoXO missions for maximizing science and applications from geostationary air quality observations into the future.
  3. Advance the science and validation facets of the TEMPO mission through organized discussions involving multiple programs, paving the way for GeoXO.
  4. Better understand the end-user and stakeholder needs of geostationary air quality data, with a special focus on the TEMPO special operations, near real-time data, and value-added products.
  5. Provide hands-on training using TEMPO proxy data to facilitate the use of operational TEMPO data and prepare the community for the future of geostationary air quality data.
