IMOS - Satellite Remote Sensing - SST - L3C - NOAA 19 - 1 day - day time - Australia

This is a single sensor, multiple swath SSTskin product for a single day-time period, derived using observations from the AVHRR instrument on the NOAA-XX 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. Only day time passes are included in the product. Each grid cell contains the 1 day 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. Matchups with buoy SST observations (adjusted to skin depths) indicate typical 2014 biases of < 0.1 degC and standard deviations of 0.5 degC to 0.6 degC for NOAA-18 and NOAA-19.

本数据集为单日时段的单传感器多扫描幅宽海表皮肤温度（SSTskin）产品，基于美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）-XX系列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。该产品采用0.02°×0.02°分辨率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°。本产品仅包含日间过境观测数据，每个网格单元内存储了所有与该单元存在空间重叠的最高质量海表温度（Sea Surface Temperature, SST）数据的日平均值，权重由重叠区域面积确定。https://help.aodn.org.au/satellite-data-product-information/ 页面中的示意图阐明了本产品在NOAA/AVHRR系列全球高分辨率海表温度研究组（Group for High Resolution Sea Surface Temperature, GHRSST）产品套件中的定位。与经皮肤深度校正的浮标海表温度观测数据的匹配验证结果显示，2014年NOAA-18与NOAA-19卫星的典型偏差小于0.1℃，标准差介于0.5℃至0.6℃之间。如需获取更多详细信息，请参阅综合海洋观测系统（Integrated Marine Observing System, IMOS）海表温度产品官网 http://imos.org.au/sstproducts.html，以及Beggs等人（2013年）的相关参考文献：http://imos.org.au/sstdata_references.html。
