NASA is hosting a media teleconference at 10 a.m. EDT Monday, March 9, to discuss an international collaboration aimed at improving our understanding of air quality. The teleconference will stream live on the agencyโ€™sย website.

Scientists from the United States, South Korea, and the Netherlands will discuss a pioneering new constellation of space-based instruments designed to advance global air quality science and monitoring.

The first part of the three-mission constellation already is in space. Last month, South Korea’s Geostationary Environment Monitoring Spectrometer (GEMS) instrument was launched aboard the GEO-KOMPSAT-2B satellite. During the next few years, GEMS will be joined by NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument and ESAโ€™s (European Space Agency’s) Sentinel-4 spacecraft. Each mission will make hourly daytime air quality measurements over different parts of the Northern Hemisphere from geostationary orbit.

Panelists for the media teleconference are:

  • Barry Lefer, tropospheric composition program manager in NASA’s Earth Science Division at agencyโ€™s headquarters, Washington
  • Jhoon Kim, GEMS principal investigator at Yonsei University, Seoul, South Korea
  • Kelly Chance, TEMPO principal investigator at the Smithsonian Astrophysical Observatory, Cambridge, Massachusetts
  • Ben Veihelmann, Sentinel-4 principal investigator for ESA, Noordwijk, The Netherlands

To participate in the call, media must contact Joe Atkinson atย joseph.s.atkinson@nasa.govย by 5 p.m. Sunday, March 8, for dial-in instructions. The public can send questions during the teleconference using the hashtag #AskNASA.
