MethaneSAT: A Breakthrough in Global Methane Emission Monitoring

MethaneSAT: A Breakthrough in Global Methane Emission Monitoring

MethaneSAT is a satellite mission aimed at tracking and measuring methane emissions globally. Launched aboard a SpaceX Falcon9 rocket, it offers significant advancements in identifying methane emissions compared to previous satellites.

Greenhouse Gas Impact

  • Methane is a potent greenhouse gas, ranking second after carbon dioxide in its contribution to global warming.
  • It’s responsible for approximately 30% of global heating since the Industrial Revolution.
  • Methane is 80 times more potent at warming than carbon dioxide over a 20-year period.

Health and Environmental Impact

  • Methane contributes to the formation of ground-level ozone, which is harmful to health.
  • Exposure to ground-level ozone may lead to approximately one million premature deaths annually.

Objectives of MethaneSAT

  • MethaneSAT aims to address the critical issue of methane emissions, primarily stemming from fossil fuel operations.
  • Developed by the Environmental Defense Fund (EDF), in partnership with Harvard University, the Smithsonian Astrophysical Observatory, and the New Zealand Space Agency.

Functionality of MethaneSAT

  • MethaneSAT will orbit the Earth 15 times a day, monitoring the oil and gas sector.
  • It will provide detailed data on methane emissions globally, including sources, trends over time, and responsible parties.
  • The collected data will be publicly available in near real-time to facilitate regulatory actions and stakeholder interventions.

Technological Advancements

  • Equipped with high-resolution infrared sensors and a spectrometer, MethaneSAT can detect methane concentrations as low as three parts per billion.
  • It has a wide-camera view, enabling identification of both small and large emitters of methane.
  • Google’s cloud-computing and AI technology will be utilized for data analysis and dissemination through the Earth Engine platform.

Impact of MethaneSAT

  • MethaneSAT’s launch coincides with the implementation of stricter methane management policies globally.
  • It will assist countries and corporations in meeting methane reduction targets, such as those outlined in the Global Methane Pledge.
  • The satellite will promote transparency by providing accessible data on methane emissions commitments.

Challenges and Considerations

  • While MethaneSAT offers valuable data, its effectiveness in influencing behavioral change among polluters remains uncertain.
  • Drew Shindell, an earth-science professor, highlights that the availability of data doesn’t guarantee a shift in emissions reduction efforts.
