New Met Office Africa-LAM dataset available from the BADC

The Met Office (UK) have developed a high resolution NWP Limited Area Model over Africa (the Africa LAM). This is running routinely and we are pleased to inform you that a selection of products from the model are now available from the NCAS British Atmospheric Data Centre (BADC) archive for use by academic researchers only.

Output fields include temperature, geopotential height, components of wind, specific humidity, cloud fraction, pressure, cloud liquid water and cloud ice content after large scale precipitation, components of gravity wave stress, convective cloud amount on each model level, etc.

Data is available for the period 2010 to present. Data covering the period January 2010 to mid-March 2011 are from the 20km 38L model configuration while data from mid-March 2011 are higher resolution from the 12km 70L model configuration.

Additional details, including geographical coverage, file format, and conditions of use, are available at:

If you have any queries in relation to this dataset, please contact the BADC Helpdesk (badc@rl.ac.uk).

Please feel free to pass this message onto colleagues who may have an interest in using this dataset.

NEW CEDA Web Processing Service for MIDAS data

Thu, 28 Jul 2011 15:57:39 -0100

NEW - CEDA Web Processing Service launched for MIDAS data

The Centre for Environmental Data Archival, which runs the BADC, is pleased to announce the beta release of the "CEDA Web Processing Service".

This initial beta release provides extraction and station searches for the Met Office's MIDAS Land Surface Station dataset held at the BADC to allow MIDAS data users to test out this functionality in preparation for the phased withdrawal of the Data Extractor service

Why are we doing this?

While one of the most widely used services at the BADC is the Data Extractor increasing extraction and subsetting demands for large and complex data by an increasing number of users means that the Data Extractor service is no longer fit for purpose. The reason for this is that the service was originally developed for a limited number of applications and was not designed to be scalable. Thus, a more robust service, with scalable computer resources to hand has been developed over the last 18 months to enable the phased replacement of the Data Extractor.

Where to access the service

The CEDA Web Processing Service is available at:

http://ceda-wps.badc.rl.ac.uk

There are instructions on how to use the service (plus additional background information about the CEDA WPS itself) on the Documentation page. However, for MIDAS users we have also put together a dedicated guide on how to carry out extractions of MIDAS data which is available here:

http://badc.nerc.ac.uk/data/ukmo-midas/WPS.html

When will the service be fully released and what are the future plans?

We have launched the CEDA Web Processing Service as a beta release initially for MIDAS users to gain feedback on the functionality offered and to have the service more heavily used. In particular we are using this phase to test out the handling of multiple asynchronous jobs to ensure that services are scaling with demand. This phase will last for 1 month after which we will aim to fully release the service. At this point we will then withdraw the MIDAS data extractions for the Data Extractor to ease demand on that service for other users of other data.

Following the successful migration of MIDAS extraction services we will then undertake a phased migration of all services presently under the Data Extractor over to the new CEDA Web Processing Service (WPS) until we are able to finally retire the Data Extractor service. In addition, thanks to the way that the CEDA WPS has been built CEDA staff will then be able to bring additional functionality to the new service allowing new services to be integrated, with the added ability to daisy-chain services together. We already have one example of a possible sequence of such services with the present release where you can use the GetWeatherStations service to find the IDs of stations in a given geographical area and then extract meteorological data for those stations using the ExtractWeatherData service.

We look forward to our users' feedback over the next month and to bring you more functionality over the coming months.
