About
The Virtual Poster Showcase is a new opportunity that allows undergraduate and graduate students to present their research virtually, alleviating any need to travel. Students not only get valuable feedback on their science, but also gain experience in reviewing the research of other students. This affordable and accessible option is ideal for students, and can help build their academic resume.

Students will first submit an abstract. The first author (and presenter) on the abstract must be an undergraduate student for the Undergraduate Showcase and a graduate student for the Graduate Showcase. Beginning in 2017, select high school students will also be able to participate.
Abstracts must be in English and submitted by the abstract submission deadline. The title is limited to 300 characters and the body is limited to 2000 characters (spaces and punctuation included). There is a $35 (US dollars) submission fee for all abstracts.
You can create your poster (with a Mac or a PC) using PowerPoint, Adobe Illustrator, Canvas, or any other program. The poster must be one page and in English. Poster dimensions are as follows: The maximum width is 48 inches (130 cm); the maximum height is 36 inches (100 cm). The file size may not exceed 25MB, and you must save your file as a PDF. The virtual poster software does not recognize any other file formats.
Once abstracts are accepted, students will submit a poster electronically along with a short video of themselves explaining the science.
Poster judging will take place in two phases:
Peer Judging: Each lead author participating in this poster showcase is required to judge three other posters and provide a score based on the visual appeal and scientific content of the poster. Students will be expected to ask questions about the posters they are judging, but please note that students will not be assigned judge other students from the same institution or research project. During the peer judging period, students must be available to log in to the virtual poster site.
Expert Judging: The second judging phase will involve experts who are scientists and faculty. The posters will be judged on scientific merit and on visual appeal. Judges will be allowed to submit comments and questions about your poster. All of their comments and questions and all of your responses will be posted online for only you to see. All of their comments and questions will be posted online and visible to other presenters and judges. You must be available to log in to the virtual poster site during the expert judging period. The site will then close, and winners will be selected and announced shortly after.
Each student will receive a certificate of participation after completing all steps of the Virtual Poster Showcase, including judging 3 peers’ posters and responding to feedback from expert judges, if appropriate. The grand prize winner of the entire showcase will receive funding towards lodging and airfare (some restrictions apply) and free registration for the 2018 Fall Meeting.
A few weeks after the conclusion of your showcase you will receive information about how to cite your abstract. Your abstract will become available in the VPS database shortly thereafter.

The Photoreactivity of Atmoshperic Dust: Quantifying Hydroxyl Radical Production Using Molecular Probes
Mineral dust taken up into the atmosphere provides an important source of radical species, such as the hydroxyl radical, as it undergoes illumination. In this study, we quantified hydroxyl radical production from Aizona Test Dust, Niger Sand, and Saharan Desert Cape Verde (SDCV) dust using a molecular probe technique, where dust is immersed in a high concentration of probe solution, which captures the hydroxyl radicals by forming a product that can be detected spectroscopically. Since the complex matrix formed by our dust-probe suspension offers unique challenges that must be overcome in order to confidently establish quantities of hydroxyl radical production, we tested different molecular probes such as coumarin, umbelliferone, benzoic acid, methanol and benzene under controlled conditions to determine the suitability of each compound. In these experiments, we found that hydroxyl radical production from dust was higher than that from source sands and that hydroxyl radical production was elevated under acidic conditions. In the future, we will use this technique to study the reactivity of dust samples from a variety of locations, and how that reactivity changes with size, atmospheric transport, and different environmental conditions.
Plant stomata couple the energy, water and carbon cycles. We use the framework of Regional Climate Modeling to simulate the 2003 European heat wave and assess how higher levels of surface CO2 may affect such an extreme event through land-atmosphere interactions. Increased CO2 modifies the seasonality of the water cycle through stomatal regulation and increased leaf area. As a result, the water saved during the growing season through higher water use efficiency mitigates summer dryness and the heat wave impact. Land-atmosphere interactions and CO2 fertilization together synergistically contribute to increased summer transpiration. This, in turn, alters the surface energy budget and decreases sensible heat flux, mitigating air temperature rise. Accurate representation of the response to higher CO2 levels, and of the coupling between the carbon and water cycles are therefore critical to forecasting seasonal climate, water cycle dynamics and to enhance the accuracy of extreme event prediction under future climate.
