The Atmospheric Circulation Reconstructions over the Earth, ACRE, is an international science project, began in 2008, that recovers historical weather observations to reconstruct past global and local weather patterns and so support meteorological reanalysis. The project aims to collect weather data from the past 250 years by linking international meteorological organisations to support data recovery projects and the imaging and digitisation of historical meteorological observations made at, for example, inland stations, lighthouses, or by ships at sea or in ports. The project aims to create historical datasets that are spatially and temporally complete, so as to be of value at a local, or regional level, as well as on a global scale. ACRE aims to recover millions of historic weather observations. This data will be deposited into two databases, *ISPD - the International Surface Pressure Databank, *ICOADS - the International Comprehensive Ocean-Atmosphere Data Set. This data will also be used to build a global dataset of historical weather reconstructions based on a grid of two degrees of latitude by two of longitude at six hourly intervals, entitled the 20th Century Reanalysis, or 20CR. Version one of 20CR, covering 1891 to 2008, was released in Autumn 2009. Version two, covering 1871 to 2010, appeared in December 2011. Plans for a third version, covering 1850 to 2011, have been put 'on hold' following a cut in the budget of NOAA. It is intended that all the data recovered and the 20CR will be made freely available.〔 ==Partners== The project has nine core partners,〔 *The Met Office Hadley Centre, *NOAA Earth System Research Laboratory, *Cooperative Institute for Research in Environmental Sciences, *NOAA National Climatic Data Center, *International Environmental Data Rescue Organization (IEDRO), *The British Library, *The University of Sussex, *The University of Giessen, *The University of Bern, *The University of Southern Queensland. In addition to the core partners, some 35 projects and other organisations are involved or have contributed recovered data. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Atmospheric Circulation Reconstructions over the Earth」の詳細全文を読む スポンサード リンク
