Code accompanying "Increasing frequency and intensity of the most extreme wildfires on Earth"

The code evaluates global trends in extreme fire activity from 2003-2023, accompanying the paper:
Cunningham, C. X., Williamson, G. J., & Bowman, D. M. J. S. (2024). Increasing frequency and intensity of the most extreme wildfires on Earth. Nature Ecology & Evolution.

The main script is broken into the following sections: (1) set up an equal area lattice; (2) clean MODIS active fire records to remove potential duplicated observations and then calculate the sum of fire radiative power (FRP sum) in each cell and each day between 2003-2023; (3) evaluate global trends in extreme events (>= 99.99th pecentile); (4-6) evaluate temporal trends within biogeographic realms and biomes; and (7) compare trends in the Terra and Aqua satellites.

The script containing custom functions is used throughout.
