High interest in “Can deep learning beat numerical weather prediction?”

We are delighted to see that in less than three months from publishing our paper “Can deep learning beat numerical weather prediction?” in Philosophical Transactions of the Royal Society, it has reached more than 8000 downloads. In addition, HPCwire (one of the leading portals on supercomputing) has covered our paper in a report that discusses in depth the main points raised in our article.

New method to produce high-resolution maps of ground-level ozone burden

A novel data fusion approach to combine the global observations from the Tropospheric Ozone Assessment Report database hosted by JSC with output from several numerical chemistry-transport models has been developed under the lead of the university of North Carolina, USA. The research has been published online March 8 by the journal Environmental Science & Technology (https://pubs.acs.org/doi/10.1021/acs.est.0c07742). The new method allows for the production of annual high-resolution maps of ground-level ozone burden, which can be combined with population density to assess the health risk from ozone air pollution. The findings from this study were used by the Global Burden of Disease 2019 (GBD2019) study, which estimated that about 365,000 people around the world died in 2019 from exposure to ozone pollution. The research used the largest compilation of ozone observations ever produced as well as estimates from nine global atmospheric models. By doing a data fusion, the research team was able to combine these different sources of information, making use of the advantages of each.

Paper on “Can deep learning beat numerical weather prediction?” published

Today, the Open Access article by Martin Schultz et.al. has been published in the Philosophical Transactions of the Royal Society A, theme issue “Machine learning for weather and climate modelling”. The paper discusses the question, whether it is possible to completely replace  the  current  numerical  weather  models  and data  assimilation  systems  with  deep learning  approaches. It is available at https://royalsocietypublishing.org/doi/10.1098/rsta.2020.0097.

AQ-Bench preprint available for public discussion

The preprint of the article “AQ-Bench: A Benchmark Dataset for Machine Learning on Global Air Quality Metrics”  by Clara Betancourt et al. is now in the public discussion phase. The manuscript is available at https://essd.copernicus.org/preprints/essd-2020-380/. It has been accepted for public discussion by the Inter-Journal Special issue “Benchmark datasets and machine learning algorithms for Earth system science data” of the Journals Earth System Science Data and Geoscientific Model Development.
The AQ-Bench dataset contains air quality data and metadata at more than 5500 air quality observation stations all over the world. It offers a low-threshold entrance to machine learning on a real world environmental dataset. The dataset itself is available at https://b2share.eudat.eu/records/30d42b5a87344e82855a486bf2123e9f . To start machine learning on the AQ-Bench dataset directly in your browser, visit the code repository (https://gitlab.version.fz-juelich.de/toar/ozone-mapping) and launch the binder!

AutoQA4Env presentation at the EGU 2020 conference

AutoQA4Env has been presented by Najmeh Kaffashzadeh in the virtual EGU conference session on atmospheric composition variability and trends. Many scientific and statistical efforts are devoted to developing advanced analytic tools or methods, but a better quantification of trend and uncertainty cannot be achieved without proper data quality control (QC). Automated QC tools are needed to allow better use of existing data, for example in the machine learning applications of the IntelliAQ project. The presentation discusses the challenges involved and presents a methodology for automated QC and its integration into the workflow used for the TOAR-database
