Fog and low-level clouds are persistent atmospheric features of western Oregon and Washington. In many ways, fog delivers benefits to local forests, agriculture, and public health by providing shading and supplemental moisture in the hot, dry summer, thereby mitigating negative effects of drought and heat stress on our natural and built communities. However, there has been little research that quantifies why, when, and where fog occurs throughout the year in the Northwest, questions that are critical to uncovering the role fog plays in our past, present, and future. Under the supervision of Dr. Alex Dye and Dr. Christopher Still, the MEP student will conduct two broad tasks: 1) use publicly available climatological datasets to help summarize when and where foggy days have occurred in the past; 2) then, the student will help summarize the weather conditions, including temperature, humidity, and wind speed/direction, that coincide with foggy days. We anticipate the student will analyze a dataset similar to the long-term records available from regional Oregon/Washington airports: https://mesonet.agron.iastate.edu/request/download.phtml. The information the student helps summarize will contribute critical understanding of the conditions that create fog in the Northwest. The project will be conducted 100% remotely, with no required field or laboratory work. Since the project is remote and purely data analysis, the student will need consistent access to a computer with internet connection.
