IMOS - SRS - SST - L3S - Multi Sensor - 3 day - night time - Australia

This is a multi-sensor SSTskin L3S product for three consecutive night-time periods, derived using sea surface temperature retrievals from the VIIRS sensor on the Suomi-NPP satellite and JPSS series of satellites, and AVHRR sensor on the NOAA and Metop series of Polar-orbiting satellites. The sensors and satellite platforms contributing to each file are listed in the sensor and platform global attributes in the file header. The Multi-sensor L3S product is provided as a 0.02deg x 0.02deg cylindrical equidistant projected map over the region 70E to 170W, 20N to 70S. The quality level for each pixel was remapped using the original ACSPO VIIRS and AVHRR L3U quality levels and Sensor Specific Error Statistics (SSES), as described in Griffin et al. (2017) Appendix at http://imos.org.au/facilities/srs/sstproducts/sstdata0/sstdata-references/, before compositing single swaths from the sensors. Each grid cell contains the 3 night average of all the highest available quality SSTs that overlap with that cell, weighted by the area of overlap.

本数据集为面向三个连续夜间时段的多传感器表层海水皮肤温度（SSTskin）L3S级产品，其数据源自Suomi-NPP卫星及JPSS系列卫星搭载的可见光红外成像辐射仪（VIIRS）、NOAA与Metop系列极轨卫星搭载的先进甚高分辨率辐射计（AVHRR）反演得到的海表温度数据。每个文件所使用的传感器与卫星平台信息，已列于文件头的传感器及平台全局属性中。本多传感器L3S级产品采用0.02°×0.02°的圆柱等距投影，覆盖区域为东经70°至西经170°、北纬20°至南纬70°。在完成各传感器单条扫描带合成前，已参考Griffin等人（2017）附录（详见http://imos.org.au/facilities/srs/sstproducts/sstdata0/sstdata-references/）所述方法，基于原始ACSPO VIIRS与AVHRR的L3U质量等级及传感器特定误差统计（SSES）对每个像素的质量等级进行重映射。每个网格单元包含与该单元重叠的所有最高可用质量海表温度数据的3晚平均值，权重为重叠区域面积。如需获取更多信息，请参阅IMOS SST产品网页：http://imos.org.au/sstproducts.html。
