Abstract:

The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.

The ISIMIP3a part of the third simulation round is dedicated to i) impact model evaluation and improvement and ii) detection and attribution of observed impacts according to the framework of IPCC AR5 Working Group II Chapter 18. To this end all simulations are driven by observed socio-economic information combined with either observed (factual) climate data or a detrended (counterfactual) version of the observed climate allowing for the generation of a “no climate change” baseline.

This dataset contains the lake area fraction (percentage of lakes in a grid cell) for the ISIMIP3a simulation round. It accounts for growing lake area fraction due to reservoir construction.

Version 1.1 of this dataset adds the 1901soc scenario with fixed year-1901 direct human influences.

Version 1.2 adds data for 2018-2021 and removes the separate lakemask files, since the lakemask can be calculated using pctlake and the grid area.

Methods:

The data are derived from the HydroLAKES v1.0 (Messager et al., 2016) and GRanD v1.3 (Lehner et al., 2011) databases and rasterized using the polygon_to_cellareafraction tool (Vanderkelen 2021, available on GitHub), and mapped to 0.5 degrees resolution. Time steps represent increasing reservoirs in their construction year, as given by GRanD.

Reservoirs from 2017 onwards are kept constant.
