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. Version 3, 20CRv3, going back to 1836, was published in October 2019. It is intended that all the data recovered and the 20CR will be made freely available.
