On April 29th, CPO’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) Program, the Chemical Sciences Lab (CSL), and National Environmental Satellite, Data, and Information Service (NESDIS) co-hosted the NOAA GEO-XO Atmospheric Composition (AC) Town Hall. Nearly 300 participants tuned in to learn more about the GEO-XO mission and the potential atmospheric composition capabilities from a NOAA geo-satellite system.
This constellation of three spacecraft will include five different types of instruments focused on operational products for weather forecasting, atmospheric composition and ocean color. Atmospheric composition capabilities come from several instruments, with the main one being the atmospheric composition instrument (ACX), an ultraviolet-visible spectrometer capable of measuring key atmospheric species relevant to air quality such as nitrogen dioxide (NO2), surface PM2.5 and surface ozone (O3).
Craig McLean (OAR Assistant Administrator) and Steve Volz (NESDIS Assistant Administrator) officially welcomed the research and user community, marking the start of the four-hour event that featured key speakers from NOAA, NASA, EPA and academia. The first session featured several overview presentations which described GEO-XO plans as they currently stand; provided some background on the developments of the TEMPO instrument and its capabilities that might be common in the ACX instrument; gave an overview of the current NOAA satellite capabilities as they relate to atmospheric composition; and presented a more detailed atmospheric composition-specific plans for GEO-XO.
The second and third sessions consisted of four short talks and a discussion by a panel of experts. The Algorithms and Products panel featured an overview of products that can be observed by the GEO-XO constellation while the Applications Panel outlined a broad cross-section of applications that could be possible with GEO-XO AC products (i.e. fire and smoke science and prediction, air quality forecasting and health.) Presentation slides from the event are available on the AC Town Hall website.
The Town Hall organizers include Monika Kopacz (NOAA/OAR/CPO), Greg Frost (NOAA/OAR/CSL), Shobha Kondragunta (NOAA/NESDIS/STAR), and Victoria Breeze (NOAA/OAR/CPO). UCAR provided logistical and technical support.
