ACT-America: The Story So Far

A NASA airborne science study looking at the transport of two major greenhouse gases in the eastern half of the U.S. just completed its fourth and next-to-last flight campaign. By measuring how weather systems move carbon dioxide and methane, Atmospheric Carbon and Transport-America, or ACT-America, aims to improve our understanding of where the gases originate and where they're being absorbed.

ACT-America Aims to Tell Four-Season Greenhouse Gas Story

NASA scientists are once again on the hunt for greenhouse gases in the sky. Researchers for the Atmospheric Carbon and Transport-America, or ACT-America, study returned to the field last week to measure how weather systems transport carbon dioxide and methane through the atmosphere over the eastern part of the United States.

Atmospheric Carbon and Transport (ACT-America)

ACT-America, or Atmospheric Carbon and Transport – America, will conduct five airborne campaigns across three regions in the eastern United States to study the transport and fluxes of atmospheric carbon dioxide and methane. Each 6-week campaign will measure how weather systems transport these greenhouse gases. The objective of the study is to enable more accurate and precise estimates of the sources and sinks of these gases.

NASA Flights to Track Greenhouse Gases Across Eastern US

Atmospheric Carbon and Transport–America, or ACT-America, is a multi-year airborne campaign that will measure concentrations of carbon dioxide and methane in relation to weather systems. The study will gather real-time measurements from research aircraft and ground stations to improve the ability to detect and quantify the surface sources and sinks of the gases.
