ISIMIP2a secondary population input data

This dataset contains improved population data available as secondary input for ISIMIP2a (https://www.isimip.org, Schewe et al. 2019).<br>While national and global population in ISIMIP2 seem consistent between historical and scenario datasets, it turns out that a given country population may be distributed differently across the grid cells corresponding to the given country, causing discontinuities in the individual grid cells population time series.<br>To overcome this issue and obtain spatially consistent historical and scenario data, the Bclimate group at the Vrije Universiteit Brussel implemented a fix. The code is available at https://github.com/VUB-HYDR/isimip2b_population_correction. See also https://data.isimip.org/issues/36/.
