Using Earth-system science at ECMWF

Lecture was delivered by Erland Kallen, Director of Research at ECMWF, in July 2013. The lecture covers most aspects of ECMWF research activities.

ERA-5 Reanalysis - High resolution atmospheric data for Earth System Modelling and evaluation

A meteorological reanalysis is a meteorological data assimilation project which aims to assimilate historical observational data spanning an extended period. These reanalysis data sets are widely used in Earth System Sciences for driving model simulations and for evaluation of earth system models and experimental data. ERA-5 comprises the most elaborated reanalysis in terms of spatial and temporal resolution as well as the data assimilation process. ERA-5 is being produced using 4DVar data assimilation in CY41R2 of ECMWF’s Integrated Forecast System (IFS), with 137 model levels in the vertical, with the top level at 80 km. The horizontal resolution is 31 km. It will cover the period January 1950 to near real time. ERA-5 data released so far covers the period 2008 - present.

Earth System Science Data (ESSD)

Open Science goes Geo - Part I: Research Data

This short course is the first part of the Short Course series 'Open Science goes Geo'. Part I covers research data and its role in the scientific work. The possibilities for publishing research data leveraging Open Science in geosciences are addressed, together with related opportunities and stumbling blocks. Moreover, the ways in which networks can support scientific collaboration on shared datasets are introduced.

Open Science is a broad movement looking beyond Open Access to publish openly and share scientific research immediately. Accessibility is addressed on all levels for everyone, without fees.

Open Science not only deals with Open Access papers but scientific research results in general, including figures, data, models, algorithms, software, tools, notebooks, laboratory designs, recipes, samples and much more. Furthermore, it covers the communication, review, and discussion of research results and considers changing needs regarding incentives, quality assessment, metrics, impact, reputation, grants and funding. Thus Open Science encompasses licensing, policy-making, infrastructures and scientific heritage while safeguarding the dynamic nature of science and its evolving forms.

However, this short course is meant not to carry too far with Open Science. Rather, it looks at what is possible nowadays and what is ready for application in geosciences. The speakers present open data solutions and introduce networks. It is aimed to create an idea on how researchers benefit from Open Science regarding research data. Both the drawbacks and opportunities of open data are outlined.

ECMWF - Precise Weather Forecasts

Collecting large amounts of data to define the current situation and processing this data through a sophisticated mathematical model are essential components for generating accurate weather forecasts. The European Centre for Medium-Range Weather Forecasts is the world leader in this field. With our animated video we convey an impression of the organisation's work.

Errand Källén - Weather Prediction and the Scalability Challenge Final

Weather prediction using high performance computing relies on having physically based models of the atmosphere that can deliver forecasts well in advance of the weather actually happening. Numerical weather prediction (NWP) is an initial value problem where globally distributed observations, coming from satellites as well as the Earth's surface and in-situ atmospheric observations, are continuously processed to define starting points for weather forecasts. Typically tens of millions of observed quantities have to be processed in real time within an hour. A forecast model is then integrated forwards in time out to two weeks ahead, also within an hour. The forecast information is subsequently distributed to users all over the world. A European intergovernmental organisation, ECMWF (European Centre for Medium range Weather Forecasts), was established forty years ago to deliver global forecast information to its member states. The forecasts have a very high quality, regular assessments conducted by the World Meteorological Organisation show that the forecasts from ECMWF are generally better than the ones produced by other weather centres around the world.
ECMWF uses HPC in order to be able to deliver the forecasts and to continuously improve the forecast quality. One of the main challenges today is to use software that can run efficiently on an HPC with hundreds of thousands of processors. Both the forecast model and the processes used for assimilating observations and distributing the forecast outputs have to be made much more efficient than they are today. Therefore ECMWF has embarked on a scalability programme together with the NWP and climate modelling community in Europe. The programme is supported by a number of EU funded research projects as well as national and intergovernmental resources. Particular research topics are numerical algorithms, big data storage and distribution and improved parallelisation of software used in all stages of the forecasting system.

The talk will give an overview of the principles underlying numerical weather prediction as well as a description of the HPC related challenges that are facing the NWP and climate modelling communities today.

European Weather Model vs. American: What's the difference?

When it comes to forecasts, there's a lot of talk about the European Model (by the ECMWF) vs. the American one (known as the GFS, and made by the National Oceanic and Atmosphere Administration). But is the European model really better? And how are they different?
