STFC Centre for Environmental Data Archival (CEDA) Annual Report 2013 (April 2012-March 2013)
No full textThe mission of the Centre for Environmental Archival (CEDA) is to deliver long term curation of
scientifically important environmental data at the same time as facilitating the use of data by the
environmental science community. CEDA was established by the amalgamation of the activities of two of
the Natural Environment Research Council (NERC) designated data centres: the British Atmospheric
Data Centre, and the NERC Earth Observation Data Centre.
We are pleased to present here our fourth annual report, covering activities for the 2013 year (April 2012
to March 2013). The report consists of two sections and appendices, the first section broadly providing a
summary of activities and some statistics with some short descriptions of some significant activities, and
a second section introducing some exemplar projects and activities. The report concludes with additional
details of activities such as publications, software maintained etc
European Atmospheric Hi-Res Model
No full textThis document describes a regionally downscaled configuration of the Unified Model, covering a European domain, with hourly forecast data covering the period T+1 to T+54 hours. With a resolution of approximately 0.04 degrees, it is able to produce selected hourly data covering the first 48 hours at surface level and at standard pressure levels four times a day. The model’s initial state is kept close to the real atmosphere by starting from a downscaled global starting condition.
This document provides details of the model configuration and output fields

Climate Change Control Systems and Technology Series
No full textMan lives in two worlds, the biosphere and the techno sphere world over the years,
time needs, growth, speed, and knowledge and competition have created demand that
necessitated man to build a complex institution. Ship design is not left out in this process.
Inland water, are under treat from untreated waste that can feed bacteria and algae, which
in turn exhaust the oxygen. The ocean covers 70 percent of the globe, many think that
everything that runs into it is infinite, the ocean is providing the source of freshening winds
and current that are far more vulnerable to polluting activities that have run off into them
too many poisons, that the ocean may cease to serve more purpose if care is not taking to
prevent pollution. This issue of the environment becomes so sensitive in recently and most are
linked to infrastructure development work. Most especially in maritime industry polluting
activities from oil bilge to ballast pumping that has turned into poison has advert effect
on water resources. Some have choked too much estuarine water where fish spawn. In a
nutshell, the two worlds we live in are currently are out of balance and in potential conflict.
Man is in the middle, and since the treat are mostly water related, ship is in the middle
too. Historical records of a number of calamities that has resulted in heavy lost and pollution
call for the environmentally sound ship. This has to lead to a number of regulations today that
will subsequently affect policies change and procedures interaction with the system. The
current situation has affected the design of new ships and modification of existing ships.
This paper review and discuss green technology emanating from regulations and highlight
new system design being driven by marine pollution prevention and, protection and control
regulation
The CMIP6 data request: The next generation climate archive
No full textA poster to show the CMIP6 data request: The next generation climate archive. Phase 6 of the World Climate Research Programme (WCRP) Coupled Model Inter-comparison Project (CMIP6) will be organised through a collection of endorsed model inter-comparison projects (MIPs) with focussed scientific objectives.
Co-ordinating teams submit proposals for experiments and data analysis to the CMIP
panel. Final proposals from 23 “Model Inter-comparison Projects” proposing analysis,
19 of them proposing a total of 195 different experiments, in addition to a core set of
“DECK” experiments and the CMIP6 Historical Simulation defined by the CMIP panel,
have been distributed to modelling groups. Endorsement of proposals will depend on
the level of support, in the form of commitments to participate;
● As part of the MIP proposals, data request templates have been filled out by each
group; this information will be consolidated and circulated to modelling groups April
15th;
● Modelling groups asked to provide commitments to the CMIP panel by April 22nd;
● A clean draft of the CMIP6 Data Request will be published at the end of July 2015;
● Version 1 CMIP6 Data Request approved at WGCM meeting (31 October 2015)

Walk softly and carry a large carrot: how to give credit for academic work
No full textA poster to show how to give credit for academic work.
Researchers want to know how their work impacts their communities, and the wider world; including research outputs other than peer-reviewed journal publications. The journal paper provides a way of claiming and defining an area of intellectual work, and citation of articles allows the acknowledgement of that work by others. Yet the paper can only give an overview of the work - it is not possible to publish everything into a paper that is needed to make it fully reproducible.
For providing credit (and for making recruitment and promotion decisions) we abstract the paper further. Instead of reading every citing paper, we instead count the citations, reckoning this an appropriate proxy for the quality of the paper, and hence the described work.
Citation counts for datasets are one of the “carrots” promised to researchers for their efforts in citing and publishing data, also producing a metric by which the quality of a dataset can be evaluated. Quality is a slippery concept when it comes to data, which can be good quality for one purpose, and bad for another. Measuring the impact of research directly is difficult, so we resort to measuring what we can (number of citations). Care must be taken with indirect measurements to ensure that they map appropriately to what we really want to measure

Optimal Estimation Method retrievals with IASI, AMSU and MHS measurements: Final Report
No full textThis report describes results from the Eumetsat study “Optimal Estimation Method retrievals with IASI, AMSU and MHS measurements”. The objectives of the study are to specify a configuration to make joint use of IASI, AMSU and MHS measurements in retrievals based on the optimal estimation method (OEM). The study characterises the added value of using MW and IR radiances in synergy for the retrievals of water vapour and temperature in cloud-free scens with the OEM in comparison to using IASI radiances only, and will also explore the potential of the method for cloudy scenes. Furthermore, the study shall characterise the impact of the loss of one or more AMSU channels
Global Atmospheric Hi-Res Model
No full textThis document describes a global configuration of the Met Office Unified Model. With a resolution of approximately 0.234 x 0.153 degrees, it is able to produce selected hourly data covering the first 48 hours at surface level and at standard pressure levels twice a day. The model’s initial state is kept close to the real atmosphere using hybrid 4D-Var data assimilation.
This document provides a detailed description of the model configuration and output variables available
