IMOS - Satellite Remote Sensing - 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.

本数据集为覆盖3个连续夜间时段的多传感器海表皮肤温度（SSTskin）L3S产品，其海表温度反演数据来源于Suomi-NPP卫星与联合极轨卫星系统（JPSS）系列卫星搭载的可见光红外成像辐射仪（VIIRS），以及美国国家海洋和大气管理局（NOAA）与Metop系列极轨卫星搭载的高级甚高分辨率辐射计（AVHRR）。每个文件所使用的传感器与卫星平台信息，均列于文件头的传感器与平台全局属性中。本多传感器L3S产品以0.02°×0.02°分辨率的圆柱等距投影格式提供，覆盖区域为东经70°至西经170°、北纬20°至南纬70°。在完成传感器单轨条带拼接前，每个像素的质量等级已基于原始ACSPO VIIRS与AVHRR L3U质量等级及传感器专属误差统计量（SSES）进行重映射，具体方法详见Griffin等人（2017）的附录，链接为http://imos.org.au/facilities/srs/sstproducts/sstdata0/sstdata-references/。每个网格单元存储的是与该单元重叠的所有最高质量等级海表温度数据的3次夜间观测平均值，权重为各数据的重叠区域面积。如需获取更多信息，请参阅IMOS海表温度产品网页：http://imos.org.au/sstproducts.html。
