Newswise — Scientists this month have successfully flown from the Arctic to the Antarctic aboard an advanced research aircraft, the first step in a three-year project to make the most extensive airborne measurements of carbon dioxide and other greenhouse gases to date.

Leaders of the research team will participate in a media teleconference at 11:00 a.m. Mountain Time (1:00 p.m. Eastern Time) Thursday, January 29, calling in from sites in the United States and Costa Rica, where the crew will make a flight layover. They will discuss preliminary findings and provide detail about the mission.

The project, known as HIPPO, will help researchers determine where and when greenhouse gases enter and leave the atmosphere, a question that is gaining urgency as the world moves toward agreements to limit greenhouse gases.

HIPPO relies on the powerful capabilities of a specially equipped Gulfstream V aircraft, owned by the National Science Foundation (NSF) and operated by the National Center for Atmospheric Research (NCAR).
