NOAA Climate Data Record (CDR) of Ocean Near Surface Atmospheric Properties, Version 2

The NOAA Ocean Surface Bundle (OSB) Climate Data Record (CDR) consist of three parts: sea surface temperature; near-surface wind speed, air temperature, and specific humidity; sensible and latent heat fluxes. This portion of the OSB CDR is the NOAA Climate Data Record (CDR) of Ocean Near Surface Atmospheric Properties. Evaluation the near-surface atmospheric temperature, humidity, and wind in comparison to similar values at the sea surface describe essential aspects of the air-sea exchange. The Special Sensor Microwave/Imager (SSM/I), a passive microwave sensor, along with the sea surface temperature CDR provide this data after application of a combination of statistical techniques using neural networks and diurnal warming parameterizations. From these data, the near-surface fluxes of evaporation/latent heat and sensible heat calculations provide the CDR final record on a 3-hourly 0.25 degree resolution grid over the global ice-free oceans.

美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）海洋表面数据集（Ocean Surface Bundle, OSB）气候数据记录（Climate Data Record, CDR）包含三个组成部分：海表温度、近地表风速、气温与比湿，以及感热通量与潜热通量。本OSB CDR的该部分即为NOAA海洋近地表大气属性气候数据记录。对近地表大气温度、湿度与风速数据与海表对应观测值进行比对，可揭示海-气交换的核心特征。专用传感器微波成像仪（Special Sensor Microwave/Imager, SSM/I）作为被动微波传感器，结合海表温度CDR，通过融合神经网络与日增温参数化方案的多种统计技术进行处理后生成该数据集。基于上述数据，通过计算近地表蒸发/潜热通量与感热通量，最终生成该CDR数据集：在全球无冰海洋区域，以3小时时间分辨率、0.25度空间分辨率的网格形式发布。
