IMOS - Satellite Remote Sensing - SST - L3S - Single Sensor - 14 day - day and night time - Australia

This is a multi-sensor SSTfnd product for a 336 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 336 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 (

本数据集为多传感器SSTfnd产品，时间跨度达336小时，基于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）观测数据反演得到。该产品以0.02°×0.02°的圆柱等距投影地图形式提供，覆盖区域为东经70°至西经170°、北纬20°至南纬70°。每个网格单元包含该单元所有重叠覆盖的最高质量海表温度观测值的336小时平均值，权重按重叠区域面积计算。https://help.aodn.org.au/satellite-data/product-information/ 页面中的图示阐明了本产品在NOAA/AVHRR系列全球高分辨率海温（Global High-Resolution Sea Surface Temperature，GHRSST）产品套件中的定位。SSTfnd产品的生成流程为：在剔除地表风速较低的观测数据后，对SSTskin观测值添加恒定偏移量0.17℃。
