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.

本数据集为单次夜间时段的多传感器海表皮层海表温度（SSTskin）L3S产品，数据衍生自Suomi-NPP卫星、JPSS系列卫星搭载的VIIRS传感器，以及NOAA与Metop系列极轨卫星搭载的AVHRR传感器反演得到的海表温度。构成每份文件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字段中。该多传感器L3S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°。在拼接各传感器的单条扫描带之前，每个像素的质量等级已基于原始ACSPO VIIRS与AVHRR L3U质量等级及传感器特定误差统计量（Sensor Specific Error Statistics, SSES）完成重映射，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/。每个网格单元包含与该单元存在空间重叠的所有最高可用质量等级海表温度的夜间单次平均结果，权重由重叠区域的面积决定。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。
