1st ACRE Workshop: Reanalyses Data,

Historical Reanalyses & Climate Applications

The aim of the workshop was to mirror the ACRE initiative, by bringing together researchers who recover, image, digitise and archive historical data for reanalyses, together with developers of various reanalyses and those from the climate applications and impacts communities who have an interest in using reanalysis products. It was hoped that in such an assembly, participants would be able to gain a better appreciation of each others’ efforts and needs so that a firmer basis for collaboration and cooperation could be forged, with users being primed in terms of their expectations of, and feedback on, the range of products that will flow from the first release of the full 20th Century Reanalysis Project (1892-2008) early in 2009. This is planned to be the first of several major workshops bringing together those involved in the full range of activities under the ACRE initiative. As a result of this first workshop, and the creation of four working groups (detailed in the body of the text) within ACRE, there will now be scope for more specific working group meetings.

2nd ACRE workshop: Shaping an ongoing road

map for ACRE

The aim of the workshop was to develop a ‘road map’ for the ACRE initiative, and greater integration between researchers recovering, imaging, digitising and archiving historical data for the historical surface-data-only reanalyses, developers of those reanalyses and the climate applications and impacts communities using reanalyses products. It was also hoped that it would provide a venue for the international release of the full 20th Century Reanalysis Project (1891-2008). Although the basics of that reanalyses were presented, an early to mid 2009 release was delayed to late 2009-early 2010. This second full ACRE workshop was followed by the first of more specific ACRE working group meetings, the ACRE WG1 Data and Data Visualisation planning meeting in Bologna, Italy from the 27- 29th May 2009. The more extensive ACRE Data and Data Visualisation meeting was held at the Met Office, Exeter in the UK from the 15-17th September 2009.

3rd ACRE Workshop:

Reanalysis and Applications

Linked to US Workshop on evaluation of recent reanalyses

& steps towards an integrated Earth System Analysis

The goal of the major ACRE Workshop for 2010 was to shape the efficient use of the products ACRE was both producing and facilitating with its international partners. Thus, this workshop brought together the main ACRE partners who had been working to use the historical weather reanalyses being produced by the NOAA and CIRES for the full range of users – from climate researchers, the diverse climate applications community, to educators and students. The applications and user communities initiated the call for an initiative like ACRE, and thus it was critical that ACRE addressed the provision of useful results that could be easily and readily applied worldwide - it was a key test in measuring ACRE’s success. The workshop also provided a venue for ACRE outreach and where preliminary results in the areas of citizen science, massive scale data handling and web-based, state-of-the-art high resolution visualisations of the data and reanalyses products could be addressed. The successful development of this technology was crucial to making the full impact of the output and outreach from the international ACRE initiative as user friendly, tailored and shaped as possible. The third ACRE workshop overlapped with the Evaluation of Reanalyses – Developing an Integrated Earth System Analysis (IESA) Capability meeting from November 1-3, 2010 .

12th ACRE Workshop

The second C3S Data Rescue Service Capacity Building Workshop took place jointly with the 12th Atmospheric Circulation Reconstructions over the Earth (ACRE) and World Meteorological Organisation (WMO) workshop at UTN, Buenos Aires, Argentina from 8th-12th April 2019. This was a five-day workshop bringing together experts and newcomers in the field of climate data rescue with a regional focus on South America. The aim was to present the state of data rescue, including available tools and support, and build a regional network in support of the C3S funded ACRE Argentina project. Combining the C3S Data Rescue Service workshop with the 12th ACRE workshop brought in additional funding, extending the workshop to five days and enabling a wider attendance of both experts and newcomers, as did support from WMO for regional experts to attend. As a result, the scope of the meeting could be extended beyond the focus region of Argentina. In total there were at least 44 participants. In addition to ten C3S experts, there were thirteen attendees from South American National Meteorological Services (NMSs), three from UTN, one each from Japan, the USA and Canada, plus five from Europe. WMO funding supported ten NMS participants, with all but Venezuela and Bolivia represented. The workshops were opened by the Director of the Argentinian Meteorological Service and Vice President of the WMO Executive Council (Celeste Saulo), and attended by the President of the WMO Commission for Climatology (Manola Brunet), and a senior officer from the WMO Data Management and Applications Division (Peer Hechler). The talks were streamed on line and eight scientists presented remotely via . Presentations could be given in English or Spanish. ACRE thanks all of the participants and especially the staff and local secretariat of our Argentine hosts, the Universidad Tecnologica Nacional (UTN) (National Technological University), for all of their support and hospitality during these workshops. Special acknowledgements go to Professor Pablo Canziani and Drs Gabriela Lakkis and Adrián Yuchechan of UTN. . . .
