Data Description

Annual precipitation, 1940 to present and future projections

Total annual precipitation (rain and snow) is the sum of daily average amounts, expressed as the depth of water reaching the ground; it excludes fog and dew. Future values are projections from climate model ensembles and show the expected range under current emissions scenarios.

Note on Data Accuracy: Estimates use satellite observations combined with climate-model outputs and are provided on ~30 km² grid averages, so uncertainty increases for smaller areas compared with exact local measurements. Future projections include confidence intervals that reflect model uncertainty.
