Beta test our new Data Extractor web-interface ============================================== We are pleased to announce the launch of a test-version of the BADC Data Extractor (dx) - a web-interface to large datasets. You can access the Data Extractor if you are registered for any of the following datasets: ECMWF ERA-40 ECMWF Operational data ECMWF ERA-15 HiGEM COAPEC HadCM3 data The Data Extractor exposes the following functionality to BADC users: Extraction of NetCDF datasets. Differencing between datasets. Browsing and selection of subsets. Selection in space and time. User-defined plotting. User-defined animation. Please note that the current version (0.1b) is only a beta-release so we invite you to test the service and give us your feedback. For more information on how to access the Data Extractor please see: http://badc.nerc.ac.uk/help/software/dx BADC Support 9th August 2004.

UTLS Ozone Data Release ======================= Data from the following UTLS Ozone projects have been released to the public domain. o DCFZ (PI: Keith Browning) o THESEO (PI: Rod Jones) o ACTO (PI: Stuart Penkett) o EGRETT (PI: Jim Whiteway) Datasets provided as a support to UTLS Ozone research have also become public. They include o Meteorolgical Images (Provider: Jamie Kettleborough) o Ozone profiles (Provider: Geraint Vaughan) o SLIMCAT 1997 Reference Atmosphere (Provider: Martyn Chipperfield) More information on these datasets can be found in the [List of UTLS Ozone Data Sets](/data/utls-ozone/data_sets.html). The data are accessible from the [UTLS Ozone archive](/cgi-bin/data_browser/data_browser/badc/utls/). General information on UTLS Ozone data can be found on the [UTLS Ozone Welcome Page](/data/utls-ozone/) at BADC. The BADC Support 9 July 2004

RPMs for the Portable Unified Model are now available from the BADC. ==================================================================== To facillitate easy installation the Met Office Portable Unified Model (PUM) RPMs for the software have been created. More information about the RPMs can be found at: [http://badc.nerc.ac.uk/data/pum/rpms.html](http://badc.nerc.ac.uk/data/pum/4.5/rpms.html) More information about the PUM code held at the BADC can be found at: BADC Support 30th April 2004

We are pleased to inform you that we have now solved the technical problem preventing access to some of the BADC datasets - all the BADC datasets are now available for download. ...

There is a problem curently affecting a storage disk. This unfortunately means that some of our datasets are currently not available for download. The service will be restored as soon as possible. We are sorry for the inconvenience this may cause in the mean time. BADC Support 27 April 2004

We have recently updated the interface to our data archive to simplify the process of downloading multiple files via the web. You can now select multiple files from multiple directories for downloading as a single gzipped tar file. For more details, go to the 'Get Data' page (http://badc.nerc.ac.uk/browse) and click on 'How to use' in the Box labelled 'Download multiple files'. BADC Support 18 March 2004

New ECMWF Seasonal Forecast (hindcast) Ensemble dataset ======================================================= In support of the COAPEC Thematic Programme the BADC has extracted ECMWF Seasonal Forecast ensemble data. These data are also known as "Hindcasts" as they are forecasts run retrospectively. The dataset includes monthly means, maxima, minima and standard deviations for the available surface variables for the period 1987-2001 (with 2002 onwards currently being extracted). Atmospheric variables are only currently available as monthly means. There are 33 parameters held on surface or single levels including winds, temperatures, heat fluxes, radiation, precipitation and soil moisture. Geopotential, Temperature, Specific Humidity, Relative Vorticity and Divergence are available on pressure levels. The data is held on a regular 1.875 x 1.875 degree grid in GRIB format. For each month there are six forecast months archived, with 5 ensemble members for 10 months of the year, and 40 ensemble members in May and November of each year. The data is now available to BADC users as part of the main ECMWF Operational archive with documentation located at: Further documentation on the seasonal forecasts is available at the following ECMWF links: BADC Support. 12th March 2004.

Bolton Experiment data now available at the BADC ================================================ The Bolton Experiment was a NERC project with matching funds from industry which took place between 1999 and 2002. The study tested the proposal that the difference in attenuation at two microwave frequencies along a given path can provide an accurate estimate of rainfall rate. The area selected for study was the town of Bolton in north-west England. More information about the Bolton Experiment data held at the BADC can be found at: ______________ BADC Support 17/02/2004

ERA-40 Live Access Server (LAS) Launched ======================================== The BADC is pleased to announce that we have launched the ERA-40 Live Access Server (LAS). This service allows sub-sets, plots and animations to be created dynamically from the ERA-40 dataset. The BADC LAS provides a multi-functional web-interface to large geospatial datasets. It is particularly suited to global gridded data such as the ERA-40 Re-analyses. Users registered for the ERA-40 data held at the BADC can log in to the BADC LAS to extract subsets of the dataset. All level types and parameters are available and all data has been transformed to a 1° x 1° grid (this was the favoured resolution in a user questionnaire). The BADC LAS allows data sub-setting in latitude, longitude, altitude and time. The output can be obtained in a number of formats including gif and postscript image files, or NetCDF data files. A limited animation facility is also available. Please note the ERA-40 LAS is only available to users that are registered for access to ERA-40. Users must log-in to the usual BADC web site before entering the LAS, after which you can go directly to the LAS in any subsequent sessions. The LAS intended for users with low data volume requirements. If it receives large requests it will ignore them and inform you that it is doing so. Moderate to high data volume users should contact BADC Support (badc@rl.ac.uk). More information about the LAS is available on the ERA-40 Regular Gridded Data page: BADC Support. 16 January 2004.
