This analytic dataset contains various environmental and socio-demographic characteristics of the state of California, daily at the resolution of 1km x 1km. All original sources of this data are open access; we share this processed dataset to facilitate replication of our paper and other exploration.

Code for this analysis (including notes on data procurement and data processing as well as generation of figures and tables for the paper) can be found here: https://github.com/EllenConsidine/LCS_placement_sims
