Ocean Near-Surface Atmospheric Properties 데이터 세트는 NOAA Ocean Surface Bundle (OSB)의 일부이며, 얼음이 없는 해양 표면의 기온, 풍속, 비습에 관한 고품질 기후 데이터 기록(CDR)을 제공합니다.
이러한 대기 속성은 신경망을 사용하여 국방 기상 위성 프로그램 (DMSP) 우주선의 특수 센서 마이크로파/이미저 (SSM/I) 및 특수 센서 마이크로파/이미저 사운더 (SSMIS)의 밝기 온도 데이터를 기반으로 계산됩니다.

CDR의 NOAA CDR 프로그램 공식 배포 지점은 NOAA의 국립 기후 데이터 센터입니다. 이 센터는 대통령의 '공개 데이터 정책'에 관한 메모에 설명되어 있고 2013년 5월 9일의 행정 명령 '정부 정보의 새로운 기본값으로 공개 및 기계 판독 가능 설정'에 따라 미국의 공개 데이터 정책 및 관행을 준수하여 CDR 패키지 및 관련 정보에 대한 지속적이고 개방적인 액세스와 적극적인 데이터 관리를 제공합니다. 이러한 정책에 따라 CDR 데이터 세트는 독점적이지 않고 공개적으로 제공되며 사용에 제한이 없습니다. 자세한 내용은 NOAA의 CDR 데이터 세트, 알고리즘, 문서의 공정 사용 PDF를 참고하세요.
