The International Atmospheric Circulation Reconstructions over Earth (ACRE) coordinates international efforts to rescue and recover global historical terrestrial and marine instrumental weather data. This event will demonstrate the value of historical data to climate services and aim to inspire more nations to participate in this global effort.

Discussion/Q&A with panel members

Rob Allan, ACRE/Met Office Hadley Centre, UK (Remote)

Prof. Rob Allan, a Scientific Manager who developed and has led the international ACRE initiative for the last 14 years, has research expertise on the El Niño Southern Oscillation (ENSO) phenomenon, low frequency climatic fluctuations, the planetary monsoon system, palaeoclimatic reconstructions and historical data analysis.

Albert Klein Tank, Head of Met Office Hadley Centre, UK (In Person)

Prof. Albert Klein Tank, who has been the Director of the Met Office Hadley Centre for Climate Science and Services since 2018, built an international reputation in climate science, particularly from his work in analyzing climate trends, developing observational datasets and producing the national climate change scenarios in the Netherlands.

Laura Slivinski, University of Colorado/CIRES & NOAA/Physical Sciences Laboratory, USA (Panel Member) (Remote)

Dr. Laura Slivinski is a co-lead scientist on version 3 of the 20th Century Reanalysis Project, an effort to estimate global weather fields and their uncertainties for the past 200 years.

Ed Hawkins, ACRE British & Irish Isles Lead/University of Reading, UK (In Person)

Prof. Ed Hawkins (MBE) is a climate scientist who leads the ACRE British and Irish Isles chapter and is known for his data visualization graphics portraying global warming, plus his lead on citizen science projects in which volunteers transcribe data from historical meteorological and rainfall records for digital analysis.

Georgina Endfield, University of Liverpool, UK (Remote)

Prof. Georgina Enfield’s expertise is in the use of historical records for the reconstruction of climate variability and environmental change, and she draws on a breadth of largely unpublished archival sources and oral history approaches.
