Capabilities and Operation of the FAAM EZLidar
No full textThe FAAM EZLidar is one of the most valuable instruments on the FAAM aircraft, which was (for example) used to measure volcanic ash in the Eyjafjallajökull ash cloud in April 2010.
This document (Observation Based Research (OBR) Technical Note 79) gives in depth information about the capabilities and operation of the instrument
Centre for Environmental Data Archival (CEDA) Current Data Holdings (August 2010)
No full textDocument presenting CEDA current data holdings as of August 2010. This includes data holdings from both the NCAS British Atmospheric Data Centre (BADC) and the NERC Earth Observation Data Centre (NEODC). Major services are also highlighted. This report was produced as part of the NERC Science Implementation Strategy (SIS) ‘Catalogue Data Holdings’ project
NERC DataGrid Security
No full textThe access control architecture developed for the NERC DataGrid. It describes how it is being extended for Single Sign On Access with the Earth System Grid for CMIP5, how trust relationships are managed in a federation and how the access control architecture can be layered over an existing site infrastructure to secure services
Untangling the influence of air-mass origin in interpreting composition trends
No full textThe UK Met office’s NAME atmospheric dispersion model has been used to develop station footprints for the Weybourne and Cape Verde Observatories, as well as two central London atmospheric stations to be used in the CleARFLo project. Back trajectory output was captured every 3 hours for several years, tracking the air mass origin for 10 days backwards in time. Monthly integrated footprints of these outputs showed a distinct seasonal variation of the air mass origins and pathways. The most common air mass pathways for each station were defined and each output was assigned to one of these trajectory types.
Classification of the pathways of the air masses reaching the measurement stations at any given time helps to link short-term changes in atmospheric composition with local pollution sources and long range transport from various areas around the stations. Long term and seasonal trends can be extracted from this and changes in the ratios and concentrations of these trace gases can be studied in a consistent manner. This classification and generation of a series of footprints can be used a resource for users of the Weybourne and Cape Verde observatories and for analysis in the Clean Air For London (CleArFLo) project
Institute of Physics, Environmental Physics Group newsletter (43), October 2010
No full textThis file contains the newsletters of the Environmental Physics Group at the Institute of Physics. The fundamental aim of the Group is to promote physics within the context of the environmental sciences. In achieving this aim we provide a forum for the discussion of physics as it applies to the environment and encourage the development and application of physical methods to environmental research. The Group also encourages the education and training of physicists in the environmental sciences through meetings and contacts with educationalists at all levels. Because of the broad nature of environmental physics the Group is involved in co-operative meetings with other professional organisations with interests in the environment. These newsletters are an archive of our activities since the formation of the Group. For more information about the Environmental Physics Group, see http://www.iop.org/activity/groups/subject/env/index.htm
Future changes in fog frequency from the UKCP09 ensemble of regional climate model projections
No full textThis report describes projections of the frequency of occurrence of fog derived from the UK Climate Projections 2009 (UKCP09) 11 member Regional Climate Model (RCM) simulations run at a 25 km resolution. These are a component of the wider suite of simulations carried out by UKCP09
