Online computing training week

ECMWF | 17-21 May 2021

Online computing training week offers webinars on a variety of topics related to software and applications used at ECMWF in both operational production and non-operational environments. The aim of the week is to provide updates on software and introduce new tools and computing activities at ECMWF. The webinars will familiarise participants with how these applications and software are used at ECMWF and provide attendees with information on how to use them effectively. The webinars are open to all, however, some products and services that will be showcased are only accessible to Member and Co-operating States.

Webinars will also include 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.

All events to be held virtually via Zoom/Blue Jeans. The joining links will be posted on this page closer to the time.


Webinar dates

Jupyter Notebooks at ECMWF

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

Milana Vuckovic, ECMWF

The Jupyter Notebook is an open-source application that allows users to create and share documents that contain live code, explanations, equations, and visualizations via web-browser. In this webinar I will give an overview of the use of Jupyter ecosystem at ECMWF for training, documentation, collaboration, and open science, as well as showcase some of the available resources.

Working with GRIB and BUFR made easier with ecCodes

Monday 17 May 14:00 to 15:00 BST (13:00 to 14:00 UTC)

Paul Dando, ECMWF

This webinar will introduce the main features of ECMWF's ecCodes package for decoding and encoding of GRIB and BUFR messages. As well as providing an overview of the command line tools and programming interfaces, tips for working efficiently with ecCodes will be provided and some recent developments highlighted.  Time will be provided for a question and answer session.

Introduction to the Atos HPC

Tuesday 18 May 10:00 to 11:00 BST (9:00 to 10:00 UTC)

Christophe Berthelot, Atos

ECMWF’s next High Performance Computer (HPC) will be from Atos and will be located in the new Bologna facility. In this webinar, Christophe Berthelot from Atos will give an introduction to the Atos HPC and an overview of what users can expect when using it.

Introduction to the Atos Test and Early Migration System (TEMS)

Tuesday 18 May 14:00 to 15:00 BST (13:00 to 14:00 UTC)

Xavier Abellan, ECMWF

Before the final HPC clusters are available on the ECMWF new Data Centre in Bologna, we are offering the possibility of testing your  applications and workloads on a smaller version of those called TEMS. Discover how you could benefit from this opportunity and how it could help you smoothen your later migration to the new ECMWF HPCF.

European Weather Cloud

Wednesday 19 May 10:00 to 11:00 BST (9:00 to 10:00 UTC)

Vasilis Baousis, ECMWF

The European Weather Cloud is a joint pilot with EUMETSAT to offer compute resources and fast data access to their Member States. The training session will cover the services the pilot system offers and demonstrate how users can access the system. Please note, that access to the cloud system is restricted to MS/CS of ECMWF.   

Ask us anything!

Wednesday 19 May 14:00 to 15:00 BST (13:00 to 14:00 UTC)

Always had a question for ECMWF but never had a chance to ask it? Well here is your opportunity to ask us anything! Submit your question and it may be answered and discussed by ECMWF experts during this session! The deadline for question submission is Wednesday 5 May 2021. Submitted questions will be assessed and a set chosen to be discussed during the session. Details of the chosen topics for discussion will be made available prior to the session.

A trip around MARS: Getting to know our Meteorological Archival and Retrieval System

Thursday 20 May 10:00 to 11:00 BST (9:00 to 10:00 UTC)

Daniel Varela Santoalla and Dominique Lucas, ECMWF

MARS, the Meteorological Archival and Retrieval System, provides access to a powerful abstraction engine that allows staff and applications to access the meteorological data that has been collected or generated at ECMWF for more than 30 years. This webinar will describe the system architecture and offer practical examples of how to find and retrieve some of the archived data. We will also pay attention to request optimisation, to ensure you can get the best possible performance at all times.

Stop, think, interpolate! The power of regridding in Metview

Thursday 20 May 14:00 to 15:00 BST (13:00 to 14:00 UTC)

Pedro Maciel, ECMWF

Often, you want to take gridded data and put it onto another grid, for example to compare the outputs from two different models. But what happens to the values when this is done - how are they selected or computed? What if you need to preserve a property of the data, for example the highest alert levels in flood warning data, or conserve volume, mass or energy? This webinar will introduce the myriad ways in which Metview can regrid your data, and give tips on how to decide between them.

CliMetLab: shared boilerplate code to get data and plot data

Friday 21 May 10:00 to 11:00 BST (9:00 to 10:00 UTC)

Florian Pinault and Baudouin Raoult, ECMWF

CliMetLab is a Python package aiming at simplifying access to climate and meteorological datasets, allowing users to focus on science instead of technical issues such as data access and data formats. It is mostly intended to be used in Jupyter notebooks, and be interoperable with all popular data analytic packages, such as Numpy, Pandas, Xarray, SciPy, Matplotlib, etc. and well as machine learning frameworks, such as Tensorflow, Keras or PyTorch.
