CARS 2009 - CSIRO Atlas of Regional Seas - Australian weekly

CARS (CSIRO Atlas of Regional Seas) is a digital climatology, or atlas of seasonal ocean water properties: temperature, salinity, dissolved oxygen, nitrate, phosphate and silicate. It comprises gridded fields of mean ocean properties over the period of modern ocean measurement, and average seasonal cycles for that period. It is derived from a quality-controlled archive of all available historical subsurface ocean property measurements - primarily research vessel instrument profiles and autonomous profiling buoys. As data availability has enormously increased in recent years, the CARS mean values are inevitably biased towards the recent ocean state.CARS2009 covers the full global oceans on a 1/2 degree grid, but until June 2011 only included temperature and salinity fields. The T and S fields were created in July 2009 and were was based on World Ocean Database 2005 (WOD05) [July 2008 Update], surface-pressure-corrected Argo global archives to May 2009, WOCE Global Hydrographic Program (v3.0), and many other datasets available up to 2008. The data was collated from many sources and rigorously screened to form BLUElink Ocean Archive (BOA).This metadata record describes all CARS parameters, which can then be visualised as a single collection through the portal interface.

CARS（区域海洋图集，CSIRO Atlas of Regional Seas）是一套数字化海洋气候数据集，即季节性海洋水特性图集，涵盖温度、盐度、溶解氧、硝酸盐、磷酸盐与硅酸盐等参数。该数据集包含现代海洋观测时段内的海洋特性平均格点场，以及该时段内的平均季节循环特征。其数据源为经过质量管控的全量可用历史海洋次表层特性观测档案，主要包括研究船仪器剖面数据与自主式剖面浮标数据。由于近年可用观测数据量大幅增长，CARS的平均值不可避免地偏向于近期的海洋状态。CARS2009采用0.5度格网覆盖全球全部海域，但在2011年6月之前仅包含温度与盐度格点场。其温、盐格点场于2009年7月构建完成，数据基础包括2005年世界海洋数据库（World Ocean Database 2005, WOD05）[2008年7月更新版]、截至2009年5月的经海面气压校正的Argo全球观测档案、WOCE全球水文计划（v3.0），以及截至2008年的其他多套可用数据集。该数据经多源整合与严格筛选后，形成BLUElink海洋档案（BLUElink Ocean Archive, BOA）。本元数据记录对CARS的全部参数进行了说明，用户可通过门户界面将这些参数集成为单一集合进行可视化展示。
