CHELSA-TraCE21k-centennial-bioclim (V1.0)
CHELSA-TraCE21k-centennial-bioclim is a global, kilometer-scale dataset generated with the CHELSA-TraCE21k downscaling model. It consists of bioclimatic and topographic variables summarized over centennial time steps from 21k BP to 0 BP.

Mean Annual Near-Surface Air Temperature
Mean annual temperature calculated as the average of mean monthly temperatures over the year
Mean Diurnal Near-Surface Air Temperature Range
Mean diurnal temperature range computed as the average of monthly daily maximum minus daily minimum near-surface air temperature
Isothermality: 100 × bio02 ÷ bio07; compares day-night variability to annual temperature range
Temperature seasonality given by the standard deviation of mean monthly temperatures
Mean Daily Maximum Near-Surface Air Temperature of the Warmest Month
Highest monthly mean of daily maximum temperatures across the year; indicates peak thermal conditions
Mean Daily Minimum Near-Surface Air Temperature of the Coldest Month
Lowest monthly mean of daily minimum temperatures across the year; characterizes winter cold intensity
Annual Daily Mean Near-Surface Air Temperature Range
Annual temperature range calculated as bio05 minus bio06; measures amplitude between warmest and coldest months
Mean Daily Near-Surface Air Temperature of the Wettest Quarter
Average monthly mean temperature over the wettest three-month period of the year
Mean Daily Near-Surface Air Temperature of the Driest Quarter
Average monthly mean temperature over the driest three-month period of the year
Mean Daily Mean Near-Surface Air Temperature of the Warmest Quarter
Average monthly mean temperature over the warmest three-month period of the year
Mean Daily Mean Near-Surface Air Temperature of the Coldest Quarter
Average monthly mean temperature over the coldest three-month period of the year
Sum of monthly precipitation totals across the year
Coefficient of variation: 100 × standard deviation ÷ mean of monthly precipitation totals
Mean Monthly Precipitation of the Wettest Quarter
Average monthly precipitation during the wettest three-month period of the year
Mean Monthly Precipitation of the Driest Quarter
Average monthly precipitation during the driest three-month period of the year
Mean Monthly Precipitation of the Warmest Quarter
Average monthly precipitation during the warmest three-month period of the year
Mean Monthly Precipitation of the Coldest Quarter
Average monthly precipitation during the coldest three-month period of the year
Elevation of the ice sheet surface above sea level.
Geometric height of the land surface above the geoid.
Number of days per year with snow cover present at the surface.
