IMOS - SRS - SST - L3S - Single Sensor - 1 day - day and night time - Australia

This is a single-sensor multi-satellite SSTfnd product for a single 24 hour period, derived using observations from AVHRR instruments on all available NOAA polar-orbiting satellites. It is provided as a 0.02deg x 0.02deg cylindrical equidistant projected map over the region 70°E to 170°W, 20°N to 70°S. Each grid cell contains the 24 hour average of all the highest available quality SSTs that overlap with that cell, weighted by the area of overlap. The diagram at https://help.aodn.org.au/satellite-data-product-information/ indicates where this product fits within the GHRSST suite of NOAA/AVHRR products. The SSTfnd is derived by adding a constant 0.17 degC to the SSTskin observations after rejecting observations with low surface wind speeds (

本数据集为单次24小时周期的多卫星单传感器海表温度基础产品（SSTfnd），数据源自所有可用美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）极轨卫星搭载的先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer, AVHRR）观测数据。
该数据集采用0.02°×0.02°的圆柱等距投影格式，覆盖区域为东经70°至西经170°、北纬20°至南纬70°。
每个网格单元包含与其空间重叠的所有最高质量等级海表温度（Sea Surface Temperature, SST）的24小时平均值，权重由重叠区域面积确定。
可通过https://help.aodn.org.au/satellite-data-product-information/ 查阅的示意图展示了本产品在NOAA/AVHRR系列全球高分辨率海表温度分析（Global High-Resolution Sea Surface Temperature Analysis, GHRSST）产品套件中的定位。
海表温度基础产品（SSTfnd）的生成流程为：在剔除海面风速过低的观测数据后，对海表温度表层（SSTskin）观测值添加恒定的0.17℃修正值。
