The Sun's recent activity has caught the interest of scientists and space weather forecasters worldwide, highlighting the need to keep a watchful eye on our star and its awesome power. On 6 and 10 September, our Sun produced a pair of solar flares, the strongest observed in over 10 years. They were accompanied by huge eruptions of billions of tonnes of matter into space. While many such eruptions fall back onto the hot surface, these two did not and became 'coronal mass ejections' (CMEs) -...

NASA's Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet's unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere. The oddball exoplanet, called WASP-12b, is one of a class of so-called "hot Jupiters," gigantic, gaseous planets that orbit very close to their host ...

    RESEARCH INTEREST

    1. Cassini Observations of Jupiter and Saturn

    The multi-filter images from the Imaging Science Subsystem (ISS) on board Cassini are utilized to explore the vortex behavior on Saturn during the time period of 2004-2011 (starting in northern winter, moving through equinox, into northern spring). Our exploration is concentrated in the northern hemisphere, which is a follow-up study of the vortex survey in the southern hemisphere (Vasavada et al., 2006). We mainly utilize ISS images from two filters (i.e., MT3 and CB2), which probe the pressure levels around the tropopause and upper troposphere, respectively. Our exploration based on the maps in 2005 and 2008 suggests that there are significantly different vortex behaviors (i.e., size, spatial distribution, and vertical structure) between the two hemispheres. We are exploring more global maps after Saturn’s spring equinox (August, 2009) to see if there are seasonal effects on the vortex behavior. Comparisons between Saturn and Jupiter can then be drawn, and models can be extended to exoplanet research.

    2. Io - Proposal

    Io is the most geologically dynamic body in the Solar System. Its surface is covered with active volcanoes (the largest in the Solar System) with plume heights in excess of 400 km above Io's surface [e.g. 1]. High temperature lavas on Io resemble Archaean-aged komatiite lavas on Earth [2], and eruptions on Io are similar in scale to those of ancient terrestrial, Martian and Venusian flood basalts [3]. Volcanism is a key geological process, and Ionian volcanism could be a potential laboratory for investigating early volcanic episodes and evolution on terrestrial planets.

    Based on the most recent planetary science decadal survey [4] and New Opportunities in Solar System Exploration (NOSSE) report [5], an Io Observer mission was included in the 2009 New Frontiers Announcement of Opportunity [6]. The decadal survey called for the Io Observer to focus on determining Io’s internal structure and to investigate the mechanisms contributing to its extensive volcanic activity. The recommended mission payload consisted of a narrow angle imager, thermal mapper, ion and neutral mass spectrometer, and a flux gate magnetometer. Here we propose an additional instrument that would enhance our understanding of Io—a dust analyzer—which would be capable of determining the composition of dust grains in Io's atmosphere and volcanic plumes, providing direct and indirect analysis of Io's volcanic activity as well as insights into Io's formation, interior and surface structure, and atmosphere.

     

    3. Evapotranspiration estimation of almond and pistachio orchards using the MODIS/ASTER Airborne Simulator (MASTER)

    The MODIS/ASTER Airborne Simulator (MASTER) was used to estimate the evapotranspiration (ET) of almond and pistachio orchards in southern California using a variety of remote sensing models including the Vegetation Index Trapezoid (VIT) method, and SEBAL and METRIC ET models. Additional inputs were acquired using the California Irrigation Management Information System (CIMIS) online weather station data for potential evapotranspiration calculations and leaf area index (LAI) data from hemispherical photography. Comparisons were made to both the CIMIS potential and reference ET, field data of crop water stress, soil moisture, the VIT method, and between the two different ET models SEBAL and METRIC. Differences in ET between the two models were minimal with a strong linear relationship. The ET results suggest little water stress in the almond and pistachio crops one to four days since watered. However, calculations using the measured data with the Thornthwaite potential ET equations and IPCC local climate change models suggest that the same amount of irrigation water would maintain a ~75% of current crop area.
