Essential climate variables for water sector applications derived from climate projections
This dataset contains 4 Essential Climate Variables (ECV) for the 18 bias adjusted Global Climate Models (GCM) from CMIP5: daily precipitation rate, and daily mean, maximum and minimum temperatures. The data are bias adjusted using the Distribution Based Scaling (DBS) method versus the global reference dataset HydroGFD2.0, both bias adjustment method and global reference dataset developed by the Swedish Meteorological and Hydrological Institute (SMHI). The DBS method is a parametric quantile-map

Useful for
- Use cases llm-inferred
- Bias-adjusted daily precipitation and temperature inputs for hydrological impact modelling of future climate scenarios · Climate-change sensitivity checks on design rainfall for drainage strategy · Future temperature trend inputs for water resources and drought planning studies
- Audience llm-inferred
- hydrologists · drainage engineers · flood consultants · water resources engineers · climate risk analysts
Limitations
- Constraints docs-verified
- CMIP5 generation of climate models (older than CMIP6) · Bias adjustment can leave some data unadjusted or outside physically plausible ranges; these cells are filled with missing values, then interpolated or copied from the nearest grid cell · Coarse 0.5° grid resolution · Temperature inconsistencies between daily mean, maximum and minimum were adjusted using climatological anomalies, which is a post-processing step
