In Europe, many efforts have been carried out towards the mitigation of the pollutants’ emissions over the last decades. However the ambient levels of some air pollutants, is still worrisome and a large part of the European population is still exposed to high levels pollution. The European Union supports the implementation of structural planning measures to control air pollution. The assessment and evaluation of these air quality policies must be carried out with the help of dedicated integrated assessment models. The use of integrated assessment models, which combine models from different fields, raises the need for developing specific modelling concepts in order to provide results to support policy decisions within a practi- cal time frame. Integrated assessment models for air policy relate technologies, the emitting sources, with air quality levels. Existing photochemical air qual- ity models are not directly suitable for integrated approaches as they are time intensive in terms of input preparation and simulation speed. This work presents the methodology and the development of a dedicated air quality model for an integrated assessment model. This approach has been designed for the Luxembourg Energy and Air Quality, LEAQ, integrated as- sessment model. It combines an air quality model, AUSTAL2000-AYLTP, with a techno-economic model, ETEM, which computes ozone precursors emissions related to energy consumption. The models are coupled via an optimization engine, which minimizes the total energy cost for a given ozone level. AUSTAL2000, a Lagrangian transport model, has been adapted to receive a photochemical module, the AsYmptotic Level Transport Pollution, AYLTP. This module consists of a Look-Up Table of quasi-linear reaction rates. The AUSTAL2000 model inquires the look-up table for pre-calculated initial condi- tions, and it reads the correspondent rate that is then used by AUSTAL2000. The look-up table has been built using a box model by simulating a large set of possible combinations of meteorological variables and precursor concen- trations. A balance has been found that gives an acceptable level of accu- racy, given the reduction of computational time. The development of such methodologies is important when considering integrated assessment models. Furthermore, the results of the air quality model have been compared with measurements, and with the regional model LOTOS-EUROS. The results of the validation are considered satisfactory for this type of approach. Addition- ally, the air quality model has been used within the in LEAQ model. Two study cases have been simulated, one including only the national emissions 2 from Luxembourg country, and a second one for the Luxembourg region, in- cluding the neighbouring countries emissions. The use of quasi-linear reaction rates obtained with the help of the look-up table represents an innovative step towards the use of simplified air quality models that involve complex chemistry.

  • Machine Learning Approaches for Outdoor Air Quality Modelling: a Systematic Review

To tackle such a limitation, the most promising approach is to use statistical models based on machine learning techniques. Nevertheless, it is puzzling why a certain algorithm is chosen over another for a given task. This systematic review intends to clarify this question by providing the reader with a comprehensive description of the principles underlying these algorithms and how they are applied to enhance prediction accuracy. A rigorous search that conforms to the PRISMA guideline is performed and results in the selection of the 46 most relevant journal papers in the area. Through a factorial analysis method these studies are synthetized and linked to each other. The main findings of this literature review show that: (i) machine learning is mainly applied in Eurasian and North American continents and (ii) estimation problems tend to implement Ensemble Learning and Regressions, whereas forecasting make use of Neural Networks and Support Vector Machines.

  • Coupling Multi-Component Models with MPH on Distributed Memory Computer Architectures
    Coupling Multi-Component Models with MPH on Distributed Memory Computer Architectures Yun He and Chris Ding Computational Research Division, Lawrence Berkeley National Laboratory University of California, Berkeley, CA 94720, USA [email protected], [email protected] Abstract A growing trend in developing large and complex applications on today’s Teraflop scale computers is to integrate stand-alone and/or semi-independent program components into a comprehensive simulation package. One example is the Community Climate System Model which consists of atmosphere, ocean, land-surface and sea-ice components. Each component is semi-independent and has been developed at a different institution. We study how this multi-component, multi-executable application can run effectively on distributed memory ar- chitectures. For the first time, we clearly identify five effective execution modes and develop the MPH library to support application development utilizing these modes. MPH performs component-name registration, resource allocation and initial component handshaking in a flex- ible way. Keywords: multi-component, multi-executable, component integration, distributed memory architecture, climate modeling, CCSM, PCM. 1 Introduction With rapid increase in computing power of distributed-memory computers, and clusters of Sym- metric Multi-Processors (SMP) application problems grow rapidly both in scale and complexity. Effectively organizing a large and complex simulation program so that it is maintainable, re-usable, sharable and efficient becomes an important task for high performance computing. Building a comprehensive application system utilizing (and modifying) existing codes developed by different groups is a standard development approach. Component-based software engineering (CBSE) is an emerging trend for software develop- ment in both research and applications.
