全球网格化的海面温度(SSTG)
海面温度(SST)是一个重要的地球物理参数,对研究全球气候变化至关重要。尽管目前可以通过各种传感器(MODIS、AVHRR、AMSR-E、AMSR2、WindSat、原地传感器)获得海面温度,但不同传感器获得的温度值来自于不同的海洋深度和不同的观测时间,因此不同的温度产品缺乏一致性
SSTG数据集是2002-2019年期间的全球海面温度数据,单位为摄氏度,时间分辨率为月度,空间分辨率为0.041°。它是通过使用温度深度和观测时间校正模型对每日原地SST数据和来自两个红外(MODIS和AVHRR)和三个无源微波(AMSR-E、AMSR2、Windsat)辐射计的每日卫星SST检索数据进行校准后产生的。准确度评估表明,重建的数据集表现出明显的改进,可用于中尺度海洋现象的分析。
