|We welcome herewith the 2nd ACCORD Newsletter.
In this NL2, several articles refer to common ACCORD efforts, such as the first thematic working weeks, consortium-wide questionnaires to better understand how the many different teams work, results from the first ACCORD-supported visits. The pandemic situation has remained an important factor in our scientific organization, forcing quite often to use video-meeting facilities as the only possible solution. Nevertheless, we acknowledge the first in-person meeting for working together on MUSC, as well as a few scientific visits that could take place. Their outcome is reported in several contributions to NL2. Like in NL1, a number of articles refer to Meteorological Quality Assurance and status reporting on national NWP systems. These contributions are found in the first part of NL2. The other thematic contributions refer to surface modelling, very high resolution modelling (hectometric or in link with LES), EPS. One specific contribution describes a starting project aimed at building an aerosol-chemistry library of codes shared by all teams in the MF Research Dept.
We do thank the contributors to newsletter number 2, and hope all ACCORD staff members find a good time reading its content.
|1st ACCORD Newsletter, published on 5 October 2021|
|We welcome herewith the very first ACCORD Newsletter, which gives an opportunity to look back at the first steps of our new consortium, with an overview article about the many facets of governance, management, bodies and tools that now form the structural backbone of ACCORD.
Model evaluation and validation appear in many of the contributions. Proposals of novel evaluation methods (like for extreme precipitation events), implementation of a new routine verification environment by one ACCORD member, specific evaluation of a new code cycle version installed on a home HPC, all provide different points of view about the quality assurance efforts in the consortium.
Fog or visibility are being addressed in four different papers of this newsletter, from various perspectives (climatology, verification, research with very high resolution configurations), illustrating the scientific challenges in this area and certainly addressing (if only indirectly) the expectations by our users.
Two articles address the challenge of forecasting temperature in mountain areas with deep valleys.
One paper explains how a high resolution LAM can be used in comparison with a coarser resolution global model for assessing the impact of sub-grid orographic drag in the global model.
Physiography data are addressed in several contributions and are likely to be a recurrent topic in the newsletter, given the needs for both accurate and new information for very high resolution modeling.
A few contributions describe progress done within the CSC physics, EPS and data assimilation systems.
The continuation of the DasKIT program within ACCORD is illustrated both by an overview article and by the realization of one member institute.
Techniques from Artificial Intelligence, like neural networks, are now more and more used in post-processing and downstream applications and there are several examples provided in this newsletter. Their use within the NWP codes remains an open area of research.
On the side of technology, making the NWP codes more easily portable and ready to face the challenges of novel HPC architectures, is discussed in two articles. One, regarding cloud services, illustrates furthermore the potential possibilities offered by cloud-based technology.
We thank the contributors to newsletter number 1, and hope all ACCORD staff members find a good time reading its content.
