Code from: Multiple environmental conditions precede Ebola spillovers in central Africa

To assess potential environmental determinants of Zaire ebolavirus (EBOV) spillovers, we analyzed time series of vegetation health, rainfall, temperature, forest loss, and human population size surrounding Central African spillover locations from 1990 to 2022. We evaluated whether environmental conditions before spillover were atypical for each location by quantifying the similarities in environmental time series between spillover years and non-spillover years. This dataset includes the environmental and anthropogenic time series analyzed around EBOV spillover locations from 1990 to 2022. These data are all publicly available and were retrieved from data repositories in Google Earth Engine, The Climate Data Store, or Worldpop.

## Description of the data and file structure

Code to accompany \"Multiple Environmental Conditions Precede Ebola Spillovers in Central Africa\" by Baranowski and Bharti, 2025, submitted to Biology Letters Special Feature on Disease Ecology. 

All data were retrieved from publicly available sources and served as input files for the code.
