中分辨率成像光谱仪（MODIS）将增加一个重要的新能力，调查70%的地球表面被海洋覆盖，除了有助于继续十年尺度的时间序列所需的海洋气候变化评估。对提高海洋产品的准确性特别重要的传感器能力包括：在较窄的谱带内具有高信噪比和高稳定性，改进机载辐射校准和稳定性监测，以及改进科学数据产品算法。用于分辨太阳激发的叶绿素荧光的光谱带和用于SST的4 μ m区域的分裂窗口将产生用于生物学和物理学的重要的新的全球海洋科学产品。中分辨率成像分光仪将以1公里的分辨率传回完整的全球数据。第2级和第3级海洋产品的完整套件进行了审查，并在许多领域中，预计中分辨率成像光谱仪数据作出重大的，新的贡献，以提高对海洋的作用，了解气候变化的认识进行了讨论。中分辨率成像光谱仪数据提供了一套高度互补和一致的陆地、大气和海洋观测数据，将提供关于地球主要组成部分之间相互作用的重要新信息。
The Moderate Resolution Imaging Spectroradiometer (MODIS) will add a significant new capability for investigating the 70% of the earth's surface that is covered by oceans, in addition to contributing to the continuation of a decadal scale time series necessary for climate change assessment in the oceans. Sensor capabilities of particular importance for improving the accuracy of ocean products include high SNR and high stability for narrower spectral bands, improved onboard radiometric calibration and stability monitoring, and improved science data product algorithms. Spectral bands for resolving solar-stimulated chlorophyll fluorescence and a split window in the 4-mu m region for SST will result in important new global ocean science products for biology and physics. MODIS will return full global data at 1-km resolution. The complete suite of Levels 2 and 3 ocean products is reviewed, and many areas where MODIS data are expected to make significant, new contributions to the enhanced understanding of the oceans' role in understanding climate change are discussed. In providing a highly complementary and consistent set of observations of terrestrial, atmospheric, and ocean observations, MODIS data will provide important new information on the interactions between earth's major components.
