ACCESS Surface 12km Australian Regional Model - Forcing dataset (for MARVL)

ACCESS-A is an archive of surface heat flux components (latent, longwave, sensible, and shortwave), surface air temperature, cloud cover, precipitation, and wind velocities surface wind velocities and mean sea-level pressure produced operationally by the Bureau of Meteorology. ACCESS-A is a regional configuration (-A denotes Australia; http://www.bom.gov.au/australia/charts/about/about_access.shtml) of ACCESS-G an atmospheric model based on the Unified Model, developed by the UKMet Office (see http://en.wikipedia.org/wiki/Unified_Model).This model differs from the ACCESS Surface 37.5km, with an improvement to the model grid spacing from 0.375o to 0.11o (approximately 12km).This is purely a description of the forcing dataset used within the MARine Virtual Laboratory (MARVL).

ACCESS-A是澳大利亚气象局（Bureau of Meteorology）业务化生成的数据集，包含地表热通量分量（潜热、长波辐射、感热、短波辐射）、地表气温、云量、降水量、地表风速以及平均海平面气压。ACCESS-A为ACCESS-G的区域配置版本（后缀-A代表澳大利亚；详细说明见http://www.bom.gov.au/australia/charts/about/about_access.shtml），而ACCESS-G是由英国气象局（UKMet Office）基于统一模式（Unified Model）开发的大气模式，相关介绍可参考http://en.wikipedia.org/wiki/Unified_Model。相较于ACCESS Surface 37.5km版本，该数据集将模式网格分辨率从0.375°提升至0.11°（约合12公里），实现了性能改进。本说明仅针对海洋虚拟实验室（MARine Virtual Laboratory, MARVL）中使用的强迫数据集进行描述。
