  • Collaborators 1) COSMO In China

    HAO Director Michael Thompson and Assistant Director for Instrumentation Steve Tomczyk recently visited China to discuss the COSMO project and other collaborations. Collaborators are pictured here, on a visit to the Nanjing Institute of Astronomical Optics & Technology (NIAOT). As well as visiting the Purple Mountain Observatory and NIAOT in Nanjing, Michael visited the National Space Science Center and National Astronomical Observatories, Chinese Academy of Sciences, in Beijing, for discussions and exploration of future collaborations.

  • Collaborators 2) Pioneering GOLD Mission

    Sept. 2011: NASA announced that the Global Observations of the Limb and Disk (GOLD) mission was selected for Phase-A Study. GOLD is a high-resolution ultraviolet spectrograph on a commercial communications satellite at geostationary orbit. Richard Eastes (UCF), is the PI. CU/LASP includes Instrument Scientist Bill McClintock and Proj. Manager Mark Lankton. HAO/NCAR leads the science team: Project Scientist Alan Burns.

  • HiWind Balloon 3) HiWind Launch

    14 June 2011: HAO's HiWind, a balloon-borne instrument that measures winds in the thermosphere, was launched from Esrange, Sweden. It ascended about 26 miles (43 kilometers) into the atmosphere and headed west across the Atlantic Ocean, passing above Greenland on its way to Canada in round-the-clock sunlight.

  • HiWind Recovery 4) HiWind's Recovery Mission

    17 June 2011: HAO's HiWind data and payload was successfully recovered! HiWind is the first balloon-borne FPI to measure the daytime thermospheric winds that are critically needed for space weather research. The HiWind payload has modest pointing requirements combined with a modest weight.

  • Solar Activity 6) Slowdown in Solar Activity

    21 June 2011: The Sun drives our climate, so a slowdown in solar activity would surely put the brakes on global warming—wouldn't it? That question percolated through the media following a set of reports from a solar physics meeting of the American Astronomical Society in Las Cruces, New Mexico.

Martin (Marty) Mlynczak is a senior research scientist in the Climate Science Branch at NASA Langley Research Center in Hampton, VA. He has been an affiliate scientist at HAO since 2000.

Marty's research is centered on understanding the climate of the whole atmosphere, troposphere to upper thermosphere. He is particularly focused on understanding the infrared radiative processes responsible for cooling the atmosphere and he currently leads (or has led) several satellite, ground-based, aircraft, balloon, and suborbital rocket experiments to observe infrared emissions in the entire sensible atmosphere. — Read More »

Scientist Highlight
Photograph of Boon Chye Low

HAO is proud to announce that Senior Scientist, Boon Chye (BC) Low, won the 2011 UCAR Outstanding Accomplishment Award for Mentoring. BC joined the High Altitude Observatory in 1981. During his 30-year-long career as an NCAR scientist (and a very productive one at that), BC has helped to enhance the professional development of numerous students, postdoctoral fellows, and junior scientists at NCAR. A brilliant theoretical and mathematical physicist himself, he has not only provided his protégés scientific and technical guidance, but more distinctively, he has inspired them with his enthusiasm and his wisdom. He is, on the one hand, selfless in devoting his time and effort to providing an enriching and supportive environment for his protégés, while also treating them as equals and giving them independence and freedom in their research and development. — Read More »
