The NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP) archive contains statistically downscaled projections at 0.25-degree horizontal resolution and a daily timestep for eight variables from 1950 to 2099. The original version of NEX-GDDP is based on an ensemble of three experiments (historical, RCP4.5, and RCP 8.5) from the larger CMIP5 archive, while a new version currently under development is based on an ensemble of three comparable experiments (historical, SSP245, and SSP585) from the recently released CMIP6 archive. While the methodology used in the creation of both versions is the same (daily bias-corrected spatial disaggregation), we will explain the nuanced differences between the two executions of that method. In addition, we will present examples of differences and similarities in output between the two versions.
