NASA NEX-GDDP 데이터 세트는 접합 대순환 모델 5 (CMIP5, Taylor et al. 2012 참고)에 따라 실행된 일반 순환 모델(GCM)에서 파생되고 대표 농도 경로 (RCP, Meinshausen et al. 2011 참고)로 알려진 4가지 온실가스 배출 시나리오 중 2가지에 걸쳐 있는 전 세계의 다운스케일링된 기후 시나리오로 구성됩니다.
CMIP5 GCM 실행은 기후 변화에 관한 정부 간 패널 (IPCC AR5)의 5차 평가 보고서를 지원하기 위해 개발되었습니다.
이 데이터 세트는 Climate Analytics Group과 NASA Ames Research Center가 NASA Earth Exchange를 사용하여 준비하고 NASA Center for Climate Simulation (NCCS)에서 배포했습니다.
