“…This development will in addition accelerate the key aim of WUDAPT, that is "to capture consistent information on urban form and function for cities worldwide that can support urban weather, climate, hydrology and air quality modeling" (Ching et al, 2018(Ching et al, , 2019. Examples of modeling systems currently using LCZ information are the Surface Urban Energy and Water Balance Scheme (SUEWS, Alexander et al, 2016), ENVI-met (Bande et al, 2020), the urban multi-scale environmental predictor (UMEP, Lindberg et al, 2018), MUKLIMO_3 (Bokwa et al, 2019;Gál et al, 2021), COSMO-CLM and the WUDAPT-TO-COSMO tool (Wouters et al, 2016;Brousse et al, 2019Brousse et al, , 2020bVarentsov et al, 2020), and the Weather Research and Forecasting model (WRF, Brousse et al, 2016;Hammerberg et al, 2018;Wong et al, 2019;Patel et al, 2020;Zonato et al, 2020). While WRF currently uses the WUDAPT-to-WRF tool to ingest LCZ information (Brousse et al, 2016), its next release expected in spring 2021 should offer this compatibility by default (A. Zonato, personal communication).…”

Since their introduction in 2012, Local Climate Zones (LCZs) emerged as a new standard for characterizing urban landscapes, providing a holistic classification approach that takes into account micro-scale land-cover and associated physical properties. In 2015, as part of the community-based World Urban Database and Access Portal Tools (WUDAPT) project, a protocol was developed that enables the mapping of cities into LCZs, using freely available data and software packages, yet performed on local computing facilities. The LCZ Generator described here further simplifies this process, providing an online platform that maps a city of interest into LCZs, solely expecting a valid training area file and some metadata as input. The web application (available at https://lcz-generator.rub.de) integrates the state-of-the-art of LCZ mapping, and simultaneously provides an automated accuracy assessment, training data derivatives, and a novel approach to identify suspicious training areas. As this contribution explains all front- and back-end procedures, databases, and underlying datasets in detail, it serves as the primary “User Guide” for this web application. We anticipate this development will significantly ease the workflow of researchers and practitioners interested in using the LCZ framework for a variety of urban-induced human and environmental impacts. In addition, this development will ease the accessibility and dissemination of maps and their metadata.

“…[10][11][12][13][14][15][16]. This leads to urban heat load which is manifested in higher air and surface temperatures compared to semi-natural surroundings [2,5,93,94]. The phenomenon of urban heat islands (UHI) is characteristic of large cities, especially those such as Belgrade, and in future research, the issue of OTC should receive attention.…”

Assessment of Outdoor Thermal Comfort in Serbia’s Urban Environments during Different Seasons

et al. 2021

The urban microclimate is gradually changing due to climate change, extreme weather conditions, urbanization, and the heat island effect. In such an altered environment, outdoor thermal comfort can have a strong impact on public health and quality of life in urban areas. In this study, three main urban areas in Serbia were selected: Belgrade (Central Serbia), Novi Sad (Northern Serbia), and Niš (Southern Serbia). The focus was on the temporal assessment of OTC, using the UTCI over a period of 20 years (1999–2018) during different seasons. The main aim is the general estimation of the OTC of Belgrade, Novi Sad, and Niš, in order to gain better insight into the bioclimatic condition, current trends and anomalies that have occurred. The analysis was conducted based on an hourly (7 h, 14 h, and 21 h CET) and “day by day” meteorological data set. Findings show the presence of a growing trend in seasonal UTCI anomalies, especially during summer and spring. In addition, there is a notable increase in the number of days above the defined UTCI thresholds for each season. Average annual UTCIs values also show a positive, rising trend, ranging from 0.50 °C to 1.33 °C. The most significant deviations from the average UTCI values, both seasonal and annual, were recorded in 2000, 2007, 2012, 2015, 2017, and 2018.

“…The previous phase has been followed (during the 20th century) by a phase mimicked by the US and Europe, qualified as "green" planning, whose fundamental focus lies on the benefits of these spaces in terms of health, urban ecology, conservation and quality of life [10][11][12][13][14]. A special interest in this planning is its role in buffering the urban heat island [15][16][17][18][19][20][21][22][23]. More recently, the beneficial role of urban trees has regained strength with respect to both public health [19,24,25] and the effects of climate change [26,27], without neglecting its biological filter action [28,29].…”

Following a copious and famous snowfall in Madrid city (Spain) and its surrounding area, the tree masses were analysed to assess the impact of this snowfall. In this way, this paper proposes an approach towards urban forest impact inventory mapping as a consequence of the snowfall of January 2021, and the subsequent atmospheric stability, which kept surface temperatures in Madrid close to −10 °C. The study has been carried out using snowfall data from 1920 to 2020 and images from the Sentinel, Landsat and MODIS satellites. The results obtained by means of image changes in the NDVI reveal a clear impact on the trees, with 11% of the winter vegetation cover of the municipality being affected. Especially significant has been the damage detected both in the forest areas in the city and in the parks, gardens or urban roads.
