IMOS - SRS - SST - L3U - NOAA 19 - Australia

This is a single sensor, single swath SSTskin product for a single overpass, without distinction between day or night. It is 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. Each grid cell contains a single observation from the AVHRR radiometer. 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.

本数据集为单次卫星过境场景下的单传感器、单幅宽海表皮肤温度（SSTskin）产品，未区分日间与夜间观测。该产品基于美国国家海洋和大气管理局（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。数据以0.02°×0.02°分辨率的圆柱等距投影地图格式提供，覆盖区域为东经70°至西经170°、北纬20°至南纬70°。每个网格单元仅包含一条AVHRR辐射计的观测记录。可通过https://help.aodn.org.au/satellite-data/product-information/ 查看该产品在NOAA/AVHRR系列全球高分辨率海表温度（GHRSST）产品套件中的定位图示。与经皮肤深度校正的浮标海表温度观测数据进行匹配比对后结果显示：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。如需获取更多信息，请参阅澳大利亚综合海洋观测系统（IMOS）海表温度产品网页http://imos.org.au/sstproducts.html，以及Beggs等人（2013年）的相关文献页面http://imos.org.au/sstdata_references.html。
