This is a 2023 draft research paper by Richard M. Medina and Simon Brewer of the University of Utah and Sean M. Kirkpatrick of the Department of Defense, prepared for journal submission and released in full by AARO in 2025. It analyzes 98,724 NUFORC public sighting reports from 2001 to 2020 by county with a Bayesian model. It finds that more light pollution and tree canopy mean fewer sightings, while more air traffic and military area mean more. Cloud cover showed no relationship.
025 with high probabilities is located in the northwest, as well as isolated counties spread throughout the eastern U.S. Figure 4 Exceedance Probability for U.S. County UAP Reported Sightings, 2001-2020 Discussion and Conclusions We recall here our initial research questions: 1) What is the viability of publicly offered data on UAP sightings? 2) Are there credible spatial patterns to these sightings? and 3) If so, can these patterns be explained by physical and/or built environment factors? For question 1, the publicly available data from NUFORC online are useable data; however, they require processing to make them usable in a GIS for spatial analysis. There are also some errors that we took the liberty of correcting based on missing coordinates due to inaccurate city name spellings. All of the necessary data are present to make this research successful, and more are provided to inform our future research on this topic. It should also be noted that these data can be used for finer resolution (city level) research, rather than county level used here. The main question that hinders our faith in the research findings is, are these volunteered data valid? The short answer is that, it is likely that some are and some aren’t. How much of this dataset is valid is questionable. However, we suggest that if the data were entirely invalid, thePage determined to be Unclassified Reviewed by Chief of Staff, AARO IAW FY24 NDAA, Section 1841 (a)(1)(C) Date: 02/06/2025
