Online training week: Software and computing at ECMWF


The online training week aims at providing webinars on specific topics related to software packages and applications used at ECMWF in the operational production and visualisation of numerical weather predictions. The objective is to provide updates on new features and to familiarise participants with the packages and applications. 

ECMWF has supercomputer facilities to run operational activities (part of CPU allocation is available to Member and Co-operating States) and a Linux cluster, available exclusively to registered users from Member and Co-operating States which can be used for graphical or other pre- and post-processing.  

ECMWF operates a large-scale data handling system, in which all ECMWF users can store and retrieve data needed to run their weather modelling activities and data mining. 

ECMWF also provides software packages specifically developed to handle data and observations coding and decoding, visualisation, data manipulation and archiving and managing of workflows. A full list of software packages available can be found on our Software page.

Course dates

13-17 May 2019

All the webinars will be in English

Visualisation of ECMWF data

Monday 13 May 10:00 to 11:00 BST (9:00 to 10:00 UTC)

This webinar will introduce software for visualising ECMWF data. Many different ways to extract visual information from data will be demonstrated. Some of these relate to choice of colour schemes and plotting algorithms, others involve some form of processing to be done as part of the visualisation. The webinar will also explore different map projections and how to combine multiple data layers onto a single map and how to combine multiple maps into a single plot.

Post-processing of ECMWF data

Tuesday 14 May 10:00 to 11:00 BST (9:00 to 10:00 UTC)

This webinar will introduce software tools for processing data from ECMWF. Operations such as regridding, sub-area extraction and field filtering will be covered, along with techniques for slicing data along different axes. Basic operations and more complex meteorological and thermodynamic functions will also be explored. The webinar will also cover aspects of handling observational data.

MARS (Meteorological Archival and Retrieval System)

Thursday 16 May 10:00 to 11:00 BST (9:00 to 10:00 UTC)

This Webinar will focus on how to retrieve data from ECMWF’s meteorological archive "MARS" efficiently and present the tools available to help users when retrieving large datasets. It will also highlight some features of MIR, the Meteorological Interpolation and Regridding library, which is now the default for those operations in MARS. All these aspects will be illustrated with some use cases.

Compiling your programs on ECMWF computers

Friday 17 May 10:00 to 11:00 BST (9:00 to 10:00 UTC)

This webinar will introduce the recommended strategies to build and run your programs at ECMWF, ranging from small post-processing tools on our ECGATE cluster to complex models on the High Performance Computing Facility. The session will build on what has been taught on the following online module

We will see how to make the most out of the modules and the different programming environments, making sure the appropriate libraries and tools are used.
