Daily Temperature Attribution

This repository contains the data for Pershing et al. "High-resolution attribution of the daily exposure of people and ecosystems to climate-driven heat" submitted to PNAS. 

The files Temperature_ChIP_{tvar}_2023.nc (tvar = 'tmax','tmin' or 'tavg') contain the daily temperatures, temperature anomalies (relative to 1991-2023) from ERA5. The variable "change_in_information" (ChIP) indicates the influence of climate change on each temperature. ChIP = log2(likelihood of T in the current climate/likelihood on climate without global warming). 

The three .csv files contain daily ChIP data from 1970-2023 aggregated over the land surface or across land biomes using area-weighted averaging and over major countries using population weighting.

The two files labeled "minimum mortality temperature" contain the annual counts of days above the 84th percentile minimum mortality temperature (or below the 16th percentile temperature). Days that meet the threshold and have ChIP>=1 are also indicated.
