IMOS - Satellite Remote Sensing - SST - L3S - Multi Sensor - 1 day - night time - Australia

This is a multi-sensor SSTskin L3S product for a single night-time period, 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 1 night average of all the highest available quality SSTs that overlap with that cell, weighted by the area of overlap.

本数据集为单夜间时段的多传感器SSTskin（海表皮肤温度）L3S产品，其数据源自Suomi-NPP卫星及JPSS系列卫星搭载的VIIRS（可见光红外成像辐射仪，Visible Infrared Imaging Radiometer Suite）传感器、NOAA与Metop系列极轨卫星搭载的AVHRR（先进甚高分辨率辐射计，Advanced Very High Resolution Radiometer）传感器的海表温度反演结果。各文件所涉及的传感器与卫星平台信息，均已列于文件头的传感器与平台全局属性字段中。本多传感器L3S产品采用0.02°×0.02°的圆柱等距投影，覆盖范围为东经70°至西经170°、北纬20°至南纬70°。在对各传感器的单轨扫描条带数据进行合成前，本产品已基于原始ACSPO VIIRS与AVHRR L3U质量等级及传感器特定误差统计量（Sensor Specific Error Statistics, SSES）完成每个像素质量等级的重映射，具体方法参见Griffin等人（2017）的附录，链接为http://imos.org.au/facilities/srs/sstproducts/sstdata0/sstdata-references/。每个网格单元包含所有与该单元存在空间重叠的最高可用质量等级海表温度数据的单夜间平均值，权重由重叠区域的面积确定。如需获取更多相关信息，请访问IMOS海表温度产品官方网页：http://imos.org.au/sstproducts.html。
