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

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 Southern Ocean region 3°E to 158°W, 27°S to 78°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，基于搭载于美国国家海洋和大气管理局（NOAA）-XX系列卫星上的高级甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）观测数据反演得到。该产品采用0.02°×0.02°的圆柱等距投影格式，覆盖南大洋区域（东经3°至西经158°，南纬27°至南纬78°）。本产品仅包含日间过境的观测数据。每个网格单元存储与该单元存在重叠的所有最高质量等级海表温度（Sea Surface Temperature，SST）数据的单日平均值，权重由重叠区域面积确定。https://help.aodn.org.au/satellite-data-product-information/ 页面中的示意图展示了本产品在NOAA/AVHRR系列全球高分辨率海表温度（Global High Resolution Sea Surface Temperature，GHRSST）产品套件中的定位。与浮标海表温度观测数据（已校正至皮肤层深度）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℃，标准差为0.5℃至0.6℃。如需获取更多详细信息，请参阅澳大利亚综合海洋观测系统（Integrated Marine Observing System，IMOS）海表温度产品网页 https://imos.org.au/sstproducts.html，以及Beggs等人（2013）的相关参考文献 https://imos.org.au/sstdata_references.html。
