MODIS Aqua Level 3 SST MID-IR Daily 9km Nighttime V2019.0

Day and night spatially gridded (L3) global NASA skin sea surface temperature (SST) products from the Moderate-resolution Imaging Spectroradiometer (MODIS) onboard the Aqua satellite. Average daily, weekly (8 day), monthly and annual skin SST products at are available at both 4.63 and 9.26 km spatial resolution. Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/ The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging. JPL acquires MODIS ocean L3 SST data from the OBPG and is the official Physical Oceanography Data Archive (PO.DAAC) for SST. The R2019.0 supersedes the previous v2014.1 datasets which can be found at https://doi.org/10.5067/MODAM-1D9N4

日间与夜间空间网格化（L3）的全球NASA皮肤海面温度（SST）产品，源自搭载于Aqua卫星上的中分辨率成像光谱仪（MODIS）。该数据集提供了每日、每周（8日）、每月及年度的平均皮肤海面温度产品，分辨率为4.63公里和9.26公里。Aqua卫星由NASA于2002年5月4日发射，进入同步太阳轨道，具有13:30的白天上升节点，与其它地球观测卫星（EOS）在A-train中进行编队飞行，旨在研究地球大气、陆地和海洋的全球动力学。MODIS在多种空间分辨率下捕捉36个光谱波段的数据。在这些文件中可能包含两种SST产品。首先是针对日间和夜间观测产生的皮肤SST，该SST由长波红外11和12微米波长通道推导，采用改进的非线性SST算法，旨在提供与NASA遗产传感器和当前传感器推导的SST的连续性。夜间，利用MODIS特有的中红外3.95和4.05微米波长通道生成第二种SST产品，该SST被称为SST4。SST4产品具有较低的误差不确定性，但由于太阳耀斑的影响，仅适用于夜间。为了生成L3产品，将L2像素合并成整数化的正弦波面积网格（ISEAG），并将其映射到等距圆柱（亦称为普拉特-卡雷投影）。有关投影的详细信息，请参阅https://oceancolor.gsfc.nasa.gov/docs/format/。NASA MODIS L3 SST数据产品由NASA海洋生物学处理组（OBPG）生成，并由位于罗森斯蒂尔海洋与大气科学学院（RSMAS）的Peter Minnett及其团队负责海面温度算法的开发、误差统计和质量标记。喷气推进实验室（JPL）从OBPG获取MODIS海洋L3 SST数据，并作为官方物理海洋学数据档案（PO.DAAC）的SST数据存储库。R2019.0版本替代了之前的v2014.1数据集，相关数据可在https://doi.org/10.5067/MODAM-1D9N4找到。
