What does the MIGHTI instrument do?

What is an interferometer? What will MIGHTI be investigating in Earth's upper atmosphere?

Karin Hauck 0 2891

ICON carries four different instruments to explore Earth's upper atmosphere. The MIGHTI instrument, an example of an interferometer, looks at winds and temperatures in the ionosphere. In this video,  Drs. John Harlander and Chris Englert explain what an interferometer is and what MIGHTI will be investigating.

"The atmosphere naturally just glows at those altitudes, more during the day and less during the night...and by just looking at the color of this airglow, we can find out about the wind and the temperature. So the atmosphere... is helping us to understand how it is behaving by sending out this airglow. If we build the right instruments to look at particular aspects of the color of the airglow, we can get information that we want."

Excitement Building for September “GEOGOLDICON” Collaborative Meeting on Space Weather

Karin Hauck 0 3846

AN NSF-supported meeting at the High Altitude Observatory in Boulder CO at the end of September is drawing participants from around the globe. Over 80 participants -- and counting -- have registered for the GEOGOLDICON conference bringing together satellite and ground-based missions exploring Earth’s near-space environment, as well as others interested in observation and analysis opportunities. (The name comes from the combination of ICON and GOLD missions and NSF Geospace). Collaborations forged at the meeting will allow leverage of each other’s work and broad participation in the investigation of long-standing mysteries and challenges, such as what effect Earth’s weather has on space weather.  The meeting is free and the invitation extended to the solar, heliospheric, magnetospheric and atmospheric communities.

The Start of ICON

Research reveals how much we’d been missing of our connection to space

Dr. Thomas Immel 0 5427

Earth’s ionosphere is chemically and dynamically complex—energized and stirred up by the aurora at the poles, concentrated and unstable at the equator. ICON focuses on this region because it is the place where coupling between our atmosphere and our space environment really occurs.  Our understanding of this relationship has come from almost a century of measurements, first from the ground and later from space.

El Niño has effects all the way to the edge of the atmosphere.

The warm El Niño conditions affecting weather around the Pacific Ocean are also affecting conditions in space, according to University of California, Berkeley scientists.

El Niño is commonly observed as a global change in rainfall due to changes in temperature in the Pacific Ocean. However, UC Berkeley scientists report today at the annual meeting of the American Geophysical Union meeting in San Francisco that the processes that lead to increased precipitation are also driving unexpected changes in the ionosphere, the uppermost level of the atmosphere.

The findings (AGU abstract #SA31F-2383) will be presented by Dr. Thomas Immel, and are based on calculations by Dr. Astrid Maute of the High Altitude Observatory in Boulder, Colorado.

“We expected that we would see some changes in the ionosphere when we started this study” says Dr. Immel, a Senior Fellow at UC Berkeley’s Space Sciences Laboratory, “but we were shocked at how strong the effect has turned out to be”.
