Institute of Physics, Environmental Physics Group newsletter (44), January 2011
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.

Supporting the climate community by providing common metadata for climate modelling digital repositories: The metafor project
No full textA poster to highlight common metadata for climate modelling repositories to support the climate community.
There is more interest than ever in the results of climate models; users are no longer limited to the scientific and academic communities, and can now be found in as diverse areas as local government, policy and the general public.
Climate modeling is a complex process, which requires accurate and complete metadata (data describing data) in order to identify, assess and use the climate data stored in digital repositories and made available to these users
An illustration of the effects of the revised Weather Generator
No full textThis document outlines the results of implementing the revised UKCP09 Weather Generator on temperature and precipitation. Both of these indices have been presented in the Weather Generator report. Each section of this note provides the changes in the tabulated indices relative to those resulting from the previous version, a commentary on what the changes are and, where possible, a potential reason for these changes

Modifications to fix the discrepancies between observed baseline climatology and future change in sunshine and vapour pressure
No full textIn September 2010, a UKCP09 user brought to our attention
that the outputs from the Weather Generator showed unrealistic changes in future sunshine hours when compared to changes in future cloud cover.
The University of East Anglia (UEA), British Atmospheric Data Centre (BADC) and the Met Office Hadley Centre have investigated the issue and this document explains where the problem comes from and how it can be rectified.
It is important to note that the problem does not stem from errors in either the probabilistic data or the Weather Generator (WG). It is due to the choice of observed baseline climatology used in generating change factors from the probabilistic projections to drive the Weather Generator. A related issue also occurs with vapour pressure, but the effect is smaller
QUALITY SUMMARY: GERB L2 ARG: 3 scan average Edition 1 product
No full textThis document must be read prior to using GERB data, and all users should determine if their use of the data is appropriate after consideration of the information
contained here.
This document is designed to inform users of the accuracy of the GERB Edition 1 level 2
ARG data products as determined by the GERB team and summarises the important validation results. The document also provides cautions on the appropriate use of the data and provides references to further, more detailed information. The document relates to the METEOSAT 8 and METEOSAT 9 GERB datasets. The Edition 1 record from these two instruments is processed with the same algorithms but the independence of the two instrumental records is maintained and any offsets between the calibration of the two instruments are not rectified. Separate validation results are therefore included as well as an inter-comparison. The operational data record from the GERB instrument on METEOSAT 8 (GERB-2) covers the period March 2004 to May 2007. From May 2007 the GERB instrument on METEOSAT 9 (GERB-1) is the operational instrument.
This document is intended as a high-level summary for scientific users of the product. It will
be updated as necessary to reflect the current knowledge of the quality of the data products. Users should re-check this document for the latest status before publication of any scientific paper using these data. More detailed information and validation results will be made available in supplementary documentation as appropriate. Users are also referred to the product user guide for additional information concerning the product contents.
Users are asked to pay particularly careful attention to section 1 of this document which contains ‘Specific Cautions’ regarding the use of the GERB level 2 ARG data
