Mature thunderstorms contain updrafts, which can be detected by polarimetric radar via a feature called a differential reflectivity (ZDR) column. As in Sharma et al.’s 2021 article, “Polarimetric and Electrical Structure of the 19 May 2013 Edmond–Carney, Oklahoma, Tornadic Supercell,” we discerned relationships between ZDR columns and lightning in a supercell thunderstorm. We applied similar analysis to a different tornadic supercell to see if their conclusions hold.

As the world shifts deeper into the virtual workspace, previous models and systematic designs become obsolete or inconvenient. To keep up with the ever-growing field of nanotechnology simulations, nanoHUB, a public platform for computation research in nanotechnology and related fields, has recently created a code library called Sim2ls. Sim2ls is a revolutionary tool allowing data processed by a simulation to be saved into a globally accessible storage area. Implementation of Sim2ls instantly allows retrieval of output data that has been run before if the same inputs were to be used, skipping the entire calculation process that could take up to several hours of runtime.

Farming activities cause particles such as soil dust and plant material to be emitted into the air. Some of these aerosols can become ice nucleating particles (INPs), serving as seeds for ice and mixed- phase clouds. While there have been ground- based studies of these particles in the western Great Plains and a single air- based study in Indiana, there is a distinct lack of ground- based studies in the Midwest. In Indiana, over two- thirds of the state is farmland, with over 75% of land in Tippecanoe County used for agriculture. Despite farming being such an essential part of life in Indiana, the connection between agricultural activities and INP concentrations in the area has not been explored. Using fi eld observations taken at the Purdue Agronomy Center for Research and Education (ACRE), we hope to study the impact of harvesting on INP concentrations in the midwestern United States. Th e fi eld experiment took place from May to December 2021 at the ACRE site, but this study focuses on three days during the harvesting period. Data was collected via two instruments: the SPectrometer for Ice Nuclei (SPIN) and the Cloud Condensation Nuclei Counter (CCNC). It appears there is an increase in INP concentrations on days when harvesting occurs, most likely due to an increase in organic and biological particles. It is hoped that the data from this project will provide further insight into the composition and number concentrations of INPs from harvesting through ground- based fi eld observations, as well as insight into INP concentration in the rural Midwest and its climatic impacts.
