  1. The Atmospheric Circulation Reconstructions over the Earth (ACRE) initiative Dr Rob Allan, ACRE Project Manager, Climate Monitoring and Attribution Group, Met Office Hadley Centre, Exeter, Devon, United Kingdom QCCCE

  2. What is ACRE? ACRE is an international collaborative initiative led by a consortium of: • the Queensland Climate Change Centre of Excellence (QCCCE) in Australia • the Met Office Hadley Centre in the UK • the US National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory (ESRL) and Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado

  3. What will ACRE do? Seamlessly: • Facilitate the recovery of historical instrumental surface terrestrial and marine global weather observations • to underpin 4D weather reconstructions (reanalyses) over the last 200-250 years • for climate applications and impacts needs worldwide. It will produce: • dynamically consistent, high resolution global historical 4D weather reconstructions at 2o latitude by 2o longitude spatial resolution every 6 hours using state-of-the-art scientific capabilities (in the future, 1/2o spatial resolution) • a baseline of 4D weather reconstructions that can be tailored and ‘downscaled’ for: • regional to local climate applications, e.g., agricultural, environmental, societal, physical • climate impacts, e.g., risk of high impact phenomena • direct weather input into biophysical and production models • an historical baseline of global weather that can be used to constrain global climate models, putting them in a much stronger position to look into the future at possible implications and impacts of climate change.

Activities in recovering, imaging and digitising historical marine and terrestrial observations • 2007/2009:British East India Company (EIC) logbooks (1780s-1830s) – held in the British Library (imaging by British Library, digitised by CDMP in US) 900 of the 2,000 logs have instrumental data [200K images]http://www.oldweather.org/examples/east-india-company • 2008/2009:Extended World War 1 period logbooks (1914-1923) - held in the UK National Archives (imaging by UK National Archives) 7,000 to8,000 logs [300K+ images] • 2007/2008:Printed/published logbooks of late 19th- early 20th Century Antarctic expeditions plus ships of exploration – online plus held in the Met Office Library & Archives (imaging & digitisation) http://www.oldweather.org/examples/TerraNova • 2008:Inventory of historical Chinese and South China Sea instrumental weather observations - an initiative in conjunction with Professor Robert Bickers, Department of Historical Studies, Bristol University and Chinese Maritime Customs Project, to produce an inventory of all the sources of historical Chinese and South China Sea region terrestrial and marine daily to sub-daily meteorological data. • 2008:British hydrographic and survey vessel remarks books (1834-1909) – held at the UK Hydrographic Office (UKHO) (inventory of holdings in the archives of the UKHO) about 6,000 remarks books • 2009/2010: CoRRal: UK Colonial registers and Royal Naval Logbooks – held at The National Archives (imaging and digitising logbooks of ships on voyages of discovery 1700-1850: ADM-55, and attached to the Hydrographic Survey 1830-1850) plus held at The National Archives and the Met Office Archives (UK colonial meteorological registers, journals and gazettes 1840-present). CoRRal: a Joint Information Systems Committee (JISC) Digitisation Programme: Enriching Digital Resources funded project.

  8. Global Historical Reanalyses Products Each of the ACRE-facilitated global historical reanalyses will produce a 56* member ensemble of some 68 4D weather variables every 6 hours at 2° latitude x 2° longitude spatial resolution over the entire globe. The ensemble mean is taken as the best analysis. Some major 4D weather variables produced by the reanalyses Geopotential Height Temperature u wind v wind Pressure vertical velocity Specific humidity Relative humidity At 19 Levels: (1000 hPa–100 hPa every 50 hpa) Others at specific levels (eg, sigma) or over the depth of the atmospheric column include: Surface pressure, Tropopause height, Precipitable water, Convective Avail. Pot. Energy, Convective inhibition, Potential temp. Total ozone, Cloud water, Sensible heat flux, Latent heat flux, Volumetric soil moisture, Accum. Snow, Downward long wave flux, Upward long wave flux, Upward short wave flux, Downward short wave flux, Precipitation rate, Convective precip. Rate, Ground heat flux, Land cover, Ice concentration, Water runoff, Potential evaporation rate, Planetary boundary layer height, Albedo, Total cloud cover, Zonal momentum flux, Meridional momentum flux. * started in November of year before, 56 random initial conditions produced from integrations of the T62 28 sigma level model forced by SSTs

  11. New partners in ACRE • Early Canada Environmental Data/Network in Canadian History & Environment (ECED/NiCHE) (http://niche.uwo.ca/early-canada-environmental-data.html): • NiCHE brings together historians, geographers, and other researchers who study nature and humans in Canada's past. It offers a forum for the field, support collaboration among scholars, and ensure that this research is shared with policymakers, scientists, and the Canadian public. ECED is a component of NiCHE, and its aims are: • to assemble digital resources that facilitate the study of historical data on Canadian environments • to design tools and explore different methods to work with such data • to bring together existing datasets and to create new databases. • This partnership will aid ACRE’s needs to link into ongoing Canadian historical data and research activities plus their outreach and outputs to community and user needs. • The Sea Around Us Project (SAUP) (http://www.seaaroundus.org/): • ACRE is exploring a potential collaboration with this initiative. SAUP is investigating the impact of fisheries on the world's marine ecosystems. This is achieved by using a Geographic Information System (GIS) to map global fisheries catches from 1950 to the present, under explicit consideration of major critical habitats of fish, marine invertebrates, marine mammals and other components of marine biodiversity. The data presented, which are freely available, are meant to support studies of global fisheries trends and the development of sustainable, ecosystem-based fisheries policies.
