Set data NASA NEX-GDDP terdiri dari skenario iklim yang di-downscale untuk seluruh dunia yang berasal dari proses menjalankan Model Sirkulasi Umum (GCM) yang dilakukan dalam Project Perbandingan Model Terhubung Fase 5 (CMIP5, lihat Taylor et al. 2012) dan di dua dari empat skenario emisi gas rumah kaca yang dikenal sebagai Representative Concentration Pathways (RCP, lihat Meinshausen et al. 2011).
Eksekusi GCM CMIP5 dikembangkan untuk mendukung Laporan Penilaian Kelima Intergovernmental Panel on Climate Change (IPCC AR5).
Set data ini disiapkan oleh Climate Analytics Group dan NASA Ames Research Center menggunakan NASA Earth Exchange, dan didistribusikan oleh NASA Center for Climate Simulation (NCCS).
