Urban areas are an important part of the climate system and many aspects of urban climate have a direct effect on human health and living conditions. This implies the need for a reliable tool for climatology studies that supports urban planning and development strategies. However, a realistic implementation of urban canopy processes still poses a serious challenge for weather and climate modelling for the current generation of numerical models. To address this demand, a new model of energy processes for urban environments was 5 developed as an Urban Surface Model (USM) and integrated as a module into the large-eddy simulation (LES) model PALM. The USM contains a multi-reflection radiation model for short and long wave radiation, calculation of the energy balance on horizontal and vertical impervious surfaces, thermal diffusion in ground, wall and roof materials and anthropogenic heat from transportation. The module also models absorption of radiation by resolved plant canopy (i.e. trees, shrubs). The USM was parallelized using MPI and performance testing demonstrates that the computational costs 10 of the USM are reasonable and the model scales well on typical cluster configurations. The module was fully integrated into PALM and is available via its online repository under GNU General Public License (GPL). The implementation was tested on a summer heat wave episode in the real conditions of a selected Prague crossroad. General patterns of temperature of various surface types (walls, pavement) are in good agreement with observations. The coupled LES-USM system appears to correct the bias found between observations and mesoscale model predictions for the near-surface air temperature. The results, however, 15 show a strong dependence on the prescribed surface and wall material properties. Their exact knowledge is thus essential for the correct prediction of the flow in the urban canopy layer.

Urban mitigation scenarios for the development area in Prague, Czech Republic were calculated by the LES model PALM extended with the urban surface model for radiation processes. Scenarios included the effect of tree planting and surface albedo adjustment on the surface temperature and NOX concentrations during a summer heat wave episode. It was shown that positive effect (cooling) in temperature can be accompanied by the increase of NOX concentration. Thus the impact of urban mitigation scenarios has to be carefully assessed from all relevant points of view.

High-quality emission data are of utmost importance for the reliable outputs of air quality models. AQ models require speciated hourly emissions, whereas emission inventories are constructed on annual basis and include only main pollutants. For the time disaggregation simple and constant monthly, daily, and hourly factors are usually used. Likewise, chemical speciations are usually based on outputs of very few and sometimes quite old reports and do not necessarily correspond to the situation in the country of interest. For the emission processing itself many scientific groups use SMOKE pre-processor, due its availability and since it is fitted for the WRF and CMAQ models. Nevertheless, its application for non-US countries can be quite complicated due to different data and metadata structure. Our project focusses on two aims: 1) The derivation of the time and speciation profiles specific for the Czech Republic. For this purpose, we analyse continuous emission measurements from the large stationary sources, temperature and behaviour dependency of the household heating emission, and the data available in the extensive Czech emission database REZZO. For the transport we managed to access data from the Electronic Control Units (ECU) of the vehicular fleet maintained by the SHERLOG company. These unique data give us information on engine state, fuel consumption, and driving styles from the real traffic flow. 2) The construction of a flexible emission processor for AQ models based on the freely available software.

Cities play an important role regarding potential climate change impacts. Urban areas are often vulnerable and poorly prepared to respond to climate change impacts, such as heat waves. Within UrbanAdapt project we aim to perform high-resolution street-level modelling to evaluate different adaptation measures which are orientated to lower the temperature in the streets during hot summer days. The heterogeneity of urbanized land surface leads to a need for a very fine resolution when modelling air flows and temperature near to the surface. We have chosen the atmospheric model PALM as a tool for our simulations. PALM is a LES model which includes parametrizations of many atmospheric processes (e.g. land surface, plant canopy, solar radiation and convective processes) and also enables to involve pollutant dispersion. On the other hand, the parametrization of building surface energy balance is not included in the model. To account for the realistic implementation of urban canopy processes in complex urban geometry we enhanced PALM model including some of the most important urban canopy mechanisms. In order to evaluate the new module, we performed a field experiment, during which temperature of building facades and road surface on Prague crossroad were measured with infrared camera, during a summer heat wave episode. Newly developed module will be used to estimate the effects of different adaptation measures (planting tree alleys, changing wall paint colors), on air quality and thermal comfort of city inhabitants.

Selected aspects of project UrbanAdapt are described. The project deals with the adaptation of cities on changing climatic conditions. The main project objective is to start the process of preparation of cities adaptation strategies, developing adaptation scenarios and testing the effects and benefits of particular measures. Project team involves groups from different fields that cover various aspects of adaptation measures including economic analyses, policy making processes, education and dissemination to the public. The presented paper deals with the part of activities which are focused on modelling of adaptation measures and climatic impacts for the city of Prague. These activities include assessment of energy balance of city, in terms of interactions of solar radiation, atmosphere and urban environment. Urban environment includes not only buildings, street surfaces and vegetation, but also the processes having impact on energy balance such as the traffic, air conditioning and industry that produce anthropogenic heat which can play a role for example in summer heat waves. The ultimate goal is to assess the impact of different adaptation measures on citizens who live in environmental conditions of growing effect of urban heat island. Thus the connection between objective meteorological variables and subjective biological indices has to be investigated. The concept of Physiological Equivalent Temperature (PET) is adopted. In comparison to single values of air temperature, air humidity, global horizontal irradiance, wind speed, and other meteorological indexes, concept of PET has added value in determining the value of important biometeorological index in easily recognizable quantity such as °C. Micro-scale models can be one way to study proposed adaptation measures such as tree alleys, bodies of water, etc.

Project UrbanAdapt deals with the adaptation of cities on changing climatic conditions including, but not limited to, summer heat waves. These activities include assessment of city's energy balance in terms of interactions of solar radiation, atmosphere, and urban environment. Micro-scale models allow studying proposed adaptation measures such as tree alleys, bodies of water, etc. The impact of different adaptation measures on citizens who live in environmental conditions of growing effect of urban heat island is investigated. For evaluating the impact of proposed strategic adaptation measures a concept of Physiological Equivalent Temperature (PET) is adopted. In comparison to single values of air temperature, air humidity, global horizontal irradiance, wind speed, and other meteorological indexes, concept of PET has added value in determining the value of important biometeorological index in easily recognizable quantity such as C degrees. Microscale models are used to downscale urbanized meteorological model to the street level and to study the connection of meteorological variables, biometeorological indices and various adaptation measures. Through these models the effects of the solar radiation (including sky view factor), radiation from buildings, air quantities and other meteorological indexes are taken into account when determining the PET.Within this contribution, various models' inputs pre-processing methods, model outputs, and the results of the proposed strategic adaptation measures impact evaluation are presented.

The paper presents the results up to now obtained within the research project UrbanAdapt. Overall, the UrbanAdapt project deals with the anthropogenic heat influence and modeling in the so-called Heat Islands, i.e. areas with great potential of accumulating the energy produced specifically by the city environment and its transformation into ambient heat. The paper introduces already identified energy sources and its transformation and transmission within specific processes between individual moving elements or building constructions. The main known energy sources such as transportation, buildings, industry, and human metabolism are discussed. The paper analyzes current measurement techniques and calculations of energy sources, their behavior and the ability to convert specific energy into the ambient heat. Mentioned are not only the impacts of vehicles, indoor air conditioning, heating, used materials mainly for roofing, but also materials involved in wall constructions, but also their ability to accumulate heat from the outside environment as well as from the indoor spaces. The paper gives an overview of available qualitative techniques for main described energy sources modeling. Relevant energy sources models and different approaches are presented and discussed.

One of the requirements on railway infrastructure administration is to provide electricity for day-to-day operation of railways. We propose a statistically based approach for the estimation of maximum 15-minute power within a calendar month for a given region. This quantity serves as a basis of contracts between railway infrastructure administration and electricity distribution system operator. We show that optimization of the prediction is possible, based on underlying loss function derived from the contract, using either a parametric or non-parametric approach.

Jednou ze složek nákladů na distribuci elektrické energie pro velkoodběratele jsou náklady na rezervovanou kapacitu. Tyto náklady se skládají z ceny za rezervovanou kapacitu, která se sjednává vždy na rok dopředu a upřesňuje se každý měsíc, a ceny za překročení této kapacity v případě, že k němu dojde. V současné době sjednává Správa železniční dopravní cesty, s.o. (SŽDC) rezervovanou kapacitu na základě expertních zkušeností s přihlédnutím k historickým datům. Cílem studie je prozkoumat možnosti snížení nákladů na rezervovanou kapacitu s využitím predikčních modelů. Základní ideou je konstrukce predikčního modelu pro měsíční maxima spotřeb trakční elektrické energie na základě historických dat o spotřebě a dalších vysvětlujících proměnných. Posléze je testována optimalizace nákladů na rezervovanou kapacitu s využitím tohoto modelu. Cílem je přitom snížit celkové náklady vhodnou kombinací cen za rezervovanou kapacitu a cen za překročení této kapacity. V rámci studie jsou uvažovány a diskutovány faktory ovlivňující spotřebu trakční elektrické energie. Některé z nich jsou zkoumány podrobněji ve vztahu k měřeným spotřebám energie a jejich měsíčním maximům. Vybrané veličiny, u nichž byl prokázán vliv na spotřebu trakční energie, jsou použity jako vysvětlující proměnné pro různé predikční modely, které byly testovány na dostupných datech. Součástí studie je hrubý návrh systému pro podporu rozhodování, který by mohl vzniknout implementací vybraného predikčního modelu a dalších získaných poznatků. Dále jsou uvedeny různé směry případného dalšího výzkumu, který by mohl vést ke zpřesnění predikce odebrané energie v následujícím roce a tím k dalšímu snížení nákladů na rezervovanou kapacitu.
