Zhen Zeng - Wide Scientific Applications of GPS Radio Occultation (RO) Observations
The COSMIC mission is another Global Positioning System radio occultation collaborative project of the United States and Taiwan. COSMIC includes six microsatellites, which were launched on Apr. 15, 2006. The main purpose of this project is to provide ~2500 real-time soundings per day with homogenous global coverage, which can potentially have major impacts on weather, climate and space weather research and forecasting.

Hugh Morrison - Cloud Microphysical Parameterizations
The representation of clouds is a major uncertainty in model simulations of weather and climate, including estimates of global climate change. Processes that impact cloud and precipitation particles, such as evaporation and particle collisions, occur on sub-centimeter scales that cannot be resolved by current models. Therefore, these microphysical processes must be parameterized. My research focuses on the development and testing of cloud microphysical parameterizations.

Sou Matsunaga - Desert Plants Have a Sunscreen for Themselves
Plants release oxygen and water vapor, but that is not all. They also emit numerous types of organic gases called as biogenic volatile organic compounds (BVOCs). Surprisingly, the total emission of BVOC on a global scale easily exceeds the entire emission of anthropogenic VOCs. For example, isoprene (2-methyl-1,3-butadiene) is one of the major BVOCs and has a factor of 10 larger emission rate than total VOC from human activity.

Peter Hjort Lauritzen - The Dynamical Core
In the heart of every weather, climate, and earth system model lies the dynamical core, which is the model component approximating a solution to the adiabatic frictionless equations of motion for the atmosphere. The next generation dynamical cores are expected to be, among other things, highly scalable. Parallel efficiency is important for fast execution on modern high-performance computers and thereby allows for higher resolution needed to resolve smaller scale dynamics. Providing modelers with dynamical cores that are accurate and efficient ultimately contributes to improving predictions of weather, climate, and other atmospheric phenomena. My research interests lie in developing numerical methods for dynamical cores and for their coupling to other model components.

Daniel Kirshbaum - Interesting Weather:

When moisture-laden airflow meets a mountain barrier, interesting weather often results. As the air is forced to rise up and over the barrier, it may saturate and produce clouds and precipitation. Moreover, the flow may also undergo a transition in stability (from stable to unstable) as it saturates, which can strongly enhance the mountain-induced precipitation.

Ada Ortiz-Carbonell - Solar Irradiance Variability:

A whole spectrum of magnetic structures can be found on the solar surface forming a hierarchy with a wide range of sizes, field strengths a degrees of compactness. My research interests are focused on the solar irradiance variability induced by the emergence of such magnetic structures into the solar photosphere, as well as in the intrinsic relationship between magnetism and solar irradiance.

Karen Shell - Understanding Climate Feedbacks in Computer Models of the Earth's Climate:

Many different feedbacks influence how the earth's temperature, precipitation, and winds respond to changes in the energy budget of the planet (caused, for example, by increases in carbon dioxide or other greenhouse gases).  One example of a climate feedback is the water vapor feedback.  As the temperature of the planet warms, the air is able to "hold" more evaporated water.  Thus, we expect the amount of water vapor, in general, to increase in a warmer climate.  However, water vapor traps some of the infrared radiation (heat) that the earth emits, further warming the planet.  Thus, the water vapor feedback is a positive feedback.
