3rd ACRE Workshop
Reanalysis and Applications (Linked
to the US Workshop
on the evaluation of recent reanalyses and steps towards an integrated
Earth System Analysis) Baltimore Sheraton Inner Harbour,
Baltimore, USA, 3rd-5th of November 2010
The Workshop would like to thank the
National Science Foundation, National Oceanic and Atmospheric Administration,
National Integrated Drought Information System,
National Aeronautics and Space Administration, US Global Climate
Observing System Program at NOAA's National Climatic Data Center,
and PlatinumRe
for their support.
Logistics
Agenda
Motivation
Over the last 3 years, the international Atmospheric Circulation
Reconstructions over the Earth (ACRE) initiative (http://www.met-acre.org/)
has progressed from a project into an international initiative that
is providing new and unique historical weather data and reconstructions
for users and climate applications needs worldwide.
With endorsement from organizations such as
the World Meteorological Organisation (WMO), the Group on Earth
Observations (GEO), the Global Climate Observing System (GCOS),
wide international support and the aid of various working groups
of GCOS and World Climate Research Program (WCRP), ACRE provides
an umbrella that links together some 35+ projects, institutions,
organisations, data rescue and climate applications activities
around the globe. In 2010, ACRE and
its activities were ratified by the WMO Commission for Climatology,
extolled in a letter of recognition from GCOS, and endorsed by the
JCOMM Expert Team on Marine Climatology.
ACRE has thus become the only international initiative of its type,
and now consists of four interwoven elements which aim to:
- undertake and facilitate the recovery of millions of historical
instrumental surface terrestrial and marine global weather observations
and to make these observations freely available via the International
Surface Pressure Databank (ISPD) and International Comprehensive
Ocean-Atmosphere Data Set (ICOADS) repositories to all international
reanalyses and users in general
- specifically support a series of successive dynamical
4D global historical weather reanalyses or reconstructions with
weather variables generated on a global grid every 6 hours at currently
2 latitude x 2 longitude resolution (with 56 realisations at each
6-hourly time step) by a numerical weather forecast model (used
in hindcast mode) assimilating only surface synoptic pressure,
monthly SST and sea-ice observations over the last 200+ years
- 20th Century Reanalysis Project: 1871-2008 [Just Released]
- Surface Input Reanalysis for Climate Applications (SIRCA):
1850-2011 [Autumn 2015]
- Chemical and Surface Input Reanalysis for Climate Applications
(CSIRCA): 1800-2016 [Autumn 2018]
- provide the above data and reanalyses freely to climate research;
climate applications, extremes, risks and impacts needs worldwide;
educators and students and the general public
- via a web-based interface that will store, allow free access
to, and enable free visualisations of, the raw data, data images,
meta data through to all of the variables generated by the 4D global
weather reanalyses/reconstructions
In support of the above ACRE activities, the
initiative has so far held two full workshops and two meetings
focusing on Working Group 1 of the initiative, on Data Rescue.
1st ACRE Workshop: Reanalyses
Data, Historical Reanalyses & Climate Applications (MeteoSwiss,
Zurich, Switzerland 23rd - 25th June 2008) (Sponsors: Partner
Re; US GCOS Office; Platinum Re; University of Bern; US Geological
Survey)
2nd ACRE Workshop: Shaping an ongoing
road map for ACRE (O’Reilly’s Rainforest Retreat,
Lamington National Park, Queensland, Australia, 1st - 3rd April,
2009) (Sponsors: CSIRO; UK High Commission in Canberra; UK
Consul in Brisbane; QCCCE; FEAST; International Relation Section
+ Department of Premier & Cabinet, Queensland State Government;
Centre for Marine Studies, University of Queensland; MCV GRDC;
Met Office)
ACRE Working Group 1 Data and Data Visualisation planning meeting
(Bologna, Italy, 27th-29th May 2009)
ACRE Data and Data Visualisation meeting. (Met Office, Exeter, UK,
15th-17th September 2009) (Sponsor: JISC)
Goal and Outcome
The goal of the major ACRE Workshop for 2010,
is to shape the efficient use of the products ACRE is both producing
and facilitating with its international partners. Thus, this workshop will bring
together the main ACRE partners who have 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 is critical that ACRE addresses the provision
of useful results that can be easily and readily applied worldwide
- it is a key test in measuring ACRE’s success.
The workshop
will also provide a venue where the results of vital interactions
between ACRE, Google, IBM and Microsoft in the area of citizen science,
massive scale data handling and web-based, state-of-the-art high
resolution visualisations of the data and reanalyses products can
be addressed. The successful development of this technology is crucial
to making the full impact of the output and outreach from the international
ACRE initiative as user friendly, tailored and shaped as is possible.
