CARS 2009 - CSIRO Atlas of Regional Seas - World monthly

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.

CSIRO区域海洋图集（CSIRO Atlas of Regional Seas，简称CARS）是一份数字化气候学数据集，亦即季节性海水属性图集，涵盖温度、盐度、溶解氧、硝酸盐、磷酸盐与硅酸盐等海水参数。该数据集包含现代海洋观测周期内的网格化平均海洋属性场，以及该周期内的平均季节性循环特征。其数据源自经过质量控制的所有可用历史次表层海洋属性测量档案，主要包括研究船仪器剖面数据与自主剖面浮标观测数据。近年来随着数据可得性大幅提升，CARS的平均值不可避免地偏向于近期的海洋状态。CARS2009以0.5度网格覆盖全球全部海域，但在2011年6月之前仅包含温度与盐度场。其温、盐场于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全球档案、WOCE全球水文计划（v3.0），以及截至2008年的其他众多数据集。该数据从多源汇集整理，并经过严格筛选，最终形成BLUElink海洋档案（BLUElink Ocean Archive，简称BOA）。本元数据记录对所有CARS参数进行了说明，用户可通过门户界面将这些参数作为单一集合进行可视化展示。
