IMOS - SRS - MODIS - 01 day - Ocean Colour - SST

The MODIS Sea Surface Temperature product is derived from MODIS bands 31 and 32 according to the algorithm described at https://oceancolor.gsfc.nasa.gov/atbd/sst/. This is not a GHRSST-quality product, and demanding applications requiring a high standard of accuracy should consider using one of the IMOS GHRSST products in preference. The MODIS SST is nevertheless useful primarily because it is measured at the same time as the water leaving radiances used to derive the optical properties (eg chl). This means it is both contemporaneous, and has a matching cloud mask, so it is valuable for applications that seek to combine both SST and optical properties (ie Net Primary Productivity variants). The data set provided here matches the Chl_oci product in temporal and spatial extent.

This SRS dataset covers waters around Australia.

MODIS海表温度（Sea Surface Temperature, SST）产品是依据https://oceancolor.gsfc.nasa.gov/atbd/sst/ 中所载算法，由MODIS第31、32波段反演生成的。该产品不属于全球高精度海表温度工作组（Group for High-Resolution Sea Surface Temperature, GHRSST）级质量产品，对于精度标准要求较高的严苛应用场景，建议优先选用IMOS旗下的GHRSST系列产品。但MODIS海表温度产品仍具备核心实用价值，因其观测时序与用于反演光学特性（如叶绿素（chlorophyll, chl））的水体离水辐射率保持一致。这意味着该产品不仅观测时序同步，还配有匹配的云掩膜数据，因此对于需同时结合海表温度与光学特性（即净初级生产力相关变体模型）的应用场景而言具有重要应用价值。本次提供的数据集在时间与空间覆盖范围上与Chl_oci产品完全匹配。
本SRS数据集覆盖澳大利亚周边海域。
