MODIS regional 8 day mean Chlorophyll-a concentration for the Australian region

MODIS regional 8 day mean Chlorophyll-a concentration for the Australian region is an experimental product generated by CSIRO. The composite images are generated by overlaying valid data of chlorophill-a concentration from the latest observation on a grid covering the Australian region. The region covered is 60S to 10N and 80E to 180E at 0.008 degrees. The chlorophyll-a product calculated from the most recent MODIS pass of the MODIS semi-analytic chlorophyll product (Chlor_a_3) is overlaid on this grid. Data that is more than 8 days old is removed and a new grid is created every four days. The data includes a time field which specifies how many days old each pixel is in relation to a reference time contained in each data file. This dataset is maintained by the CSIRO Marine and Atmospheric Research Center and listed on their OPeNDAP catalog, access is available through the TPAC Climate and Ocean Digital Library.中分辨率成像光谱仪（MODIS）区域8日平均叶绿素a浓度澳大利亚区域数据集是由澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation，CSIRO）生成的试验性产品。该合成影像通过将最新观测所得的叶绿素a浓度有效数据叠加至覆盖澳大利亚区域的网格而生成。数据集覆盖范围为南纬60°至北纬10°、东经80°至180°，空间分辨率为0.008°。本次采用的叶绿素a产品由最新一次MODIS过境的MODIS半分析叶绿素产品（Chlor_a_3）计算得到，并叠加至上述网格。时效超过8天的数据将被移除，每4日生成一组新的网格数据。该数据集包含时间字段，用于标注每个像素相对于各数据文件中参考时间的天数。 本数据集由澳大利亚联邦科学与工业研究组织海洋与大气研究中心维护，并收录于其OPeNDAP目录，可通过TPAC气候与海洋数字图书馆获取访问权限。
