Bias-corrected CORDEX Climate Change Database for the Nile Basin

SYDRO, on behalf of the Nile Basin Initiative (NBI) and GIZ, has completed the Climate Service Infrastructure Project (CSI), which provides gridded dataset products (historical and bias-corrected climate change projections) for the whole Nile Basin. Sydro has derived Probable Maximum Precipitation and Intensity-Duration-Frequency curves and deployed them together with the bias-corrected time series to the Nile Basin Knowledge Portal (IKP). The following climate and hydrological variables are available at 0.44° spatial and 1 day temporal resolution:

  • Precipitation time series
  • Temperature time series (max/min)
  • Intensity Duration Frequency curves (IDF)
  • Probable Maximum Precipitation (PMP)

The time horizons of these datasets cover:

  • 1971 – 2000 (historical)
  • 2006 – 2035 (near future)
  • 2036 – 2065 (mid-century future)
  • 2066 – 2095 (far-century future)

The underlying RCP scenarios are:

  • RCP 4.5 (intermediate climate change scenario)
  • RCP 8.5 (worst case climate change scenario)

Through this website, the water and climate community is enabled to use reliable and tested climate change projections of the entire Nile Basin to conduct their own studies. A manual is available at the IKP portal providing guidance on how to download and apply the data. Data access is possible through this link:
