Precipitation of driest month — SSP3-7.0 2071-2100 (CHELSA)
This layer projects how much rainfall the driest month of a typical year will see late this century, under a high-emissions future.

What it shows
This layer projects how much rainfall the driest month of a typical year will see late this century, under a high-emissions future. It is a forward-looking bioclimatic indicator describing the depth of the seasonal dry period, which governs water availability, vegetation stress and the long-term suitability of land for crops and ecosystems.
How it is built
The layer comes from CHELSA-CMIP6 v2.1 (Karger et al.) under the SSP3-7.0 scenario for the 2071-2100 period, based on a single climate model (MPI-ESM1-2-HR). The variable is the projected precipitation total of the driest calendar month at end of century. It is delivered on a fine global grid of roughly 2 km. Being a future projection drawn from one model, it should be read as a plausible long-term outlook rather than a precise forecast.
How to read it
Higher values indicate a wetter driest month — a milder future dry season; lower values indicate a more severe future seasonal drought. The layer is most informative when compared against the 1981-2010 baseline variant to reveal the direction and size of projected change.

Comparison with the WWF Risk Filter Suite
The WWF Risk Filter Suite publishes present-day indicators and no standalone bioclimatic precipitation projections. This is a forward-looking climate-scenario variant with no distinct WWF equivalent, and is a Darwin extension.
