“…Although there are many complex and multi-variant based methods for determining bioclimatic comfort, one of the best indices for estimating the effective temperature is the DI index [50], also known as Thom's discomfort index (THI) [36]. This index is based on the effective temperature and humidity conditions and describes the degree of discomfort by categories covering the whole spectrum from cold to tropical climates.…”

Extreme heat poses significant risks to the world's growing urban population, and the heat stress to human health is likely to escalate with the anthropogenically increased temperatures projected by climate models. Thus, the additional heat from the urban heat island (UHI) effect needs to be quantified, including the spatial pattern. This study focuses on the city of Valencia (Spain), investigating the intensity and spatial pattern of UHI during three consecutive hot summer days accompanying a heat record. For the analysis, long-term in situ measurements and remote sensing data were combined. The UHI effect was evaluated using two approaches: (a) based on air temperature (AT) time-series from two meteorological stations and (b) using land surface temperature (LST) images from MODIS products by NASA with 1 km resolution. The strongest nighttime UHI estimated from AT was 2.3 • C, while the most intense surface UHI calculated as the difference between the LST of urban and rural regions (defined by NDVI) was 2.6 • C-both measured during the night after the record hot day. To assess the human thermal comfort in the city the Discomfort Index was applied. With the increasing number of tropical nights, the mitigation of nighttime UHI is a pressing issue that should be taken into consideration in climate-resilient urban planning.

“…Studies show that the world is experiencing rapid urbanisation, with 45% of all the population already living in urban areas as of year 2000 (Arnfield 2003). Urban is defined as an environment where the density of population and economic activities are more than in other places with higher rate of destruction of natural resources (Toy et al, 2007).…”

“…Average THI values were used for the evaluation of bioclimatic conditions (Table 2) as modified from Toy et al (2007). It has been reported that the discomfort levels of a precursor index, the Thom's index, were predicted in the Greater Athens Area using artificial neural network models during the hot season of the year (Vouterakos et al, 2012).…”

This research aims to investigate the bioclimatic conditions in different ground cover types in the greater Athens area, Greece: a major street with heavy traffic (MS), an adjacent pedestrian street (PS) with irrigated plants and an urban park. Four sites were selected: one in each of the streets, and two in the park, one of which is covered by irrigated plants (IPS) while the other is covered by non-irrigated plants (NIPS). Air temperature and relative humidity were monitored in each site during the periods of July-August and September-October of the years 2009 and 2010. These parameters were used for the calculation of the thermohygrometric index based on which bioclimatic conditions were evaluated. The "Hot" class prevailed at all sites during the July-August period while similar bioclimatic conditions detected at all environments with irrigated plants at the aforementioned period. During autumn, the "Comfortable" class prevailed at the PS and the urban park compared to the MS. The findings of our study could provide useful information for the design of outdoor spaces with irrigated vegetation as well as for the plantation and irrigation of plant species on city roads with heavy traffic.
