2011 Events

Events and activities from 2011

  • Dr. Ruby Leung, a Laboratory Fellow at the Pacific Northwest National Laboratory, Department of Energy, and a visitor of JIFRESSE, presented a seminary entitled "Mega-Droughts in North America: The Role of Biosphere-Atmosphere Feedbacks" at the Atmospheric and Oceanic Sciences Department on November 9, 2011.

  • Professor Yongyung Hu, Chair of the Atmospheric and Oceanic Department at Peking University, presented a seminar entitled, "Stratospheric ozone recovery may enhance greenhouse warming in the 21st century" at the UCLA Atmospheric and Oceanic Department on October 5, 2011. Professor Hu is a visitor of JIFRESSE. Director Liou and Professor Qinbin Li are developing a collaboration program with Peking University in the areas of climate and environmental sciences under the purview of the MOU between UCLA and Peking University on Sciences and Engineering.

  • On September 2, 2011, JIFRESSE hosted a mini-workshop at UCLA with a delegation from the Center for Climate Change and Sustainable Development at National Taiwan University (NTU). (PDF of Agenda) (PDF of Delegate List)

  • UCLA Chancellor Gene Block and JPL Director Charles Elachi signed a revised Memorandum of Understanding (MOU) for JIFRESSE on August 17, 2011.

  • Director K.N. Liou gave a talk as a Distinguished Lecturer in Atmosphere Sciences at the Asia Oceania Geosciences Society (AOGS) 8th annual meeting in Taipei, Taiwan on August 9, 2011. The talk was entitled, "Regional Climate Change: The Role of Light-Absorbing Aerosols and Snow-Albedo Feedback." (PDF of Lecture & Slides) (PDF of Plaque)

  • Yi Chao, Adjunct Professor of Atmospheric and Oceanic Science (UCLA) and JIFRESSE Visiting Researcher is the Project Scientist for JPL’s recently launched (June 9, 2011) Aquarius Mission. The mission’s objective is to collect data on varying sea surface salinity levels, to improve understanding about ocean circulation, and to understand how these changes affect the global water cycle and climate change. News coverage about the mission is available at the following links: (1) (2) (3) (4) (5) (6). Aquarius is a joint mission between NASA and the Argentina Space Agency (Link).

  • Calvin Liang, a graduate student supported by JIFRESSE, has completed his Ph.D. degree from UCLA under the supervision of Director K.N. Liou and JPL Scientist Annmarie Eldering. His thesis is entitled, "A multi-sensor perspective on the tropical interannual variability of humidity and clouds." Calvin is currently employed at Northrop Grumman, and is also partly supported by JPL.

  • On May 6, 2011, the Vatican released "A Report by the Working Group Commissioned by the Vatican's Pontifical Academy of Sciences," a study on climate change of which JPL Research Scientist Thomas Painter was a co-author. (Link to New York Times Article & PDF of Report).

  • Professor V. Ramanathan of the Scripps Institution of Oceanography at the University of California, San Diego, gave a special Atmospheric and Oceanic Sciences Seminar on April 29, 2011 entitled "Limiting Global Warming Below Dangerous Levels: Practical Approaches and Major Issues." He also discussed with Director Liou the issue of climatic impacts of black carbon in the atmosphere.

  • Dr. Tim Liu, a JIFRESSE Visiting Researcher and a Senior Scientist at JPL, has been elected a Fellow of the American Geophysical Union, an honor reserved for only 0.1% of the total membership per year. Dr. Liu has made pioneering contributions to the satellite remote sensing of surface winds over the oceans which have led to the improvement of weather predictions using computer models.

  • A number of papers have recently been published by JIFRESSE researchers, graduate students and Director Liou. Graduate student Calvin Liang published a paper entitled “Record of tropical interannual variability of temperature and water vapor from a combined AIRS-MLS data set” (J. Geophys. Res., 2011, PDF). Researcher Yu Gu published 2 papers, “Direct climate effect of black carbon in China and its impact on dust storms” (J. Geophys. Res., 2010, PDF) and “Cirrus cloud simulations using WRF with improved radiation parameterization and increased vertical resolution” (J. Geophys. Res., 2011, PDF). Visiting researchers Jonathan Jiang and Hui Su published a paper entitled “Influence of convection and aerosol pollution on ice cloud particle effective radius” (J. Atmos. Chem. Phys., 2011, PDF). Research Associate W.L. Lee published a paper, "Parameterization of solar fluxes over mountain surfaces for application to climate model" (J. Geophys. Res., 2011, PDF). Director Kuo-Nan Liou also recently published a paper, entitled “Light absorption and scattering by aggregates: Application to black carbon and snow grains” (J. Quant. Spectrosc. Radiat. Transfer, 2011, PDF).

  • JIFRESSE Executive Committee member Professor Alex Hall has just returned to UCLA for the Spring 2011 quarter, having been on sabbatical in Paris, France.

  • JIFRESSE researcher Sassan Satchi has begun supporting two UCLA graduate students, Chelsea Robinson in the Geography department and Yifan Yu from the Atmospheric & Oceanic Sciences department.

  • Dr. Moustafa Chahine from JPL, a close friend of Director K. N. Liou and strong supporter of JIFRESSE, passed away unexpectedly on March 23, 2011. Link to Dr. Chahine’s memorial page.

  • A JIFRESSE Executive Committee meeting was held at the JIFRESSE Conference Room in 9249 Boelter Hall on March 3, 2011 . Several important items were discussed. Agenda (PDF).

  • Jim Hansen, a leading climate scientist, gave two lectures as part of the Mautner Memorial Lecture Series at UCLA. The first was a research lecture on Climate Sensitivity on February 22, 2011, and the second was a public lecture entitled “Human-Made Climate Change: A Scientific, Moral and Legal Issue,” given the following day.
