Set data Ocean Near-Surface Atmospheric Properties adalah bagian dari NOAA Ocean Surface Bundle (OSB) dan menyediakan Climate Data Record (CDR) berkualitas tinggi tentang suhu udara, kecepatan angin, dan kelembapan spesifik di atas permukaan laut bebas es.
Properti atmosfer ini dihitung berdasarkan data suhu kecerahan dari Special Sensor Microwave/Imager (SSM/I) dan Special Sensor Microwave/Imager Sounder (SSMIS) di pesawat ruang angkasa Defense Meteorological Satellite Program (DMSP), menggunakan jaringan saraf tiruan.
