O conjunto de dados de propriedades atmosféricas perto da superfície do oceano faz parte do pacote de superfície oceânica (OSB, na sigla em inglês) da NOAA e fornece um registro de dados climáticos (CDR, na sigla em inglês) de alta qualidade de temperatura do ar, velocidade do vento e umidade específica em superfícies oceânicas sem gelo.
Essas propriedades atmosféricas são calculadas com base em dados de temperatura de brilho do Special Sensor Microwave/Imager (SSM/I) e do Special Sensor Microwave/Imager Sounder (SSMIS) na espaçonave do Defense Meteorological Satellite Program (DMSP), usando uma rede neural.
