The Year of Polar Prediction (YOPP) was created to improve weather prediction models and thus make weather forecasts more accurate. Ensuring that people have accurate and timely information about upcoming weather events is critical to ensuring human health and safety. Although YOPP focuses specifically on the polar regions, improving weather forecasts in the Arctic will lead to better forecasts across the world. The focus of this research was understanding low-level temperature inversions, which can reflect and affect larger-scale weather events. Understanding more about them will foster further knowledge of other aspects of the atmosphere, such as Arctic haze. Radiosonde profiles from UtqiaÄĄvik, Alaska collected during YOPP Special Observing Periods (SOPs), throughout which more data was gathered than is standard, were analyzed in this research.
