HyADS output adjacency matrix (HyADSmat.Rda)

This file is a weighted adjacency matrix denoting the influence of each of 505 coal power plants on each of 40577 US ZIP codes in 2005, with influence determined by the HyADS dispersion model. It is also known as a "source-receptor" matrix. This version of the adjacency matrix is not weighted by power plant emissions.More details about the HyADS dispersion model can be found in:Henneman L, Choirat C, Ivey C, Cummiskey K, Zigler C. Characterizing Population Exposure to Coal Emissions Sources in the United States using the HyADS Model. Atmospheric Environment, 2019; 203, 271-280.Henneman L, Choirat C, Dedoussi I, Dominici F, Roberts J, and Zigler CM. Mortality risk from United States coal electricity generation. Science, 2023; 382(6673).This version of the HyADS adjacency matrix is used, for example, in the paper:Zigler C, Liu V, Mealli F, and Forastiere L.
