“…The inclusion of both thermo-physiological indices permitted (i) the comparison of PET results against those obtained by a newly adapted mPET index; and (ii) the scrutiny of whether the application of mPET in this study would also collaborate with the general the results obtained by Chen and Matzarakis [31] for western European climates. When cross-examining the outcomes of the two indices for July and December in Figure 4, two major distinctions were acknowledged.…”

“…The second step was orientated at processing the results through the updated version of the RayMan model (ii) in order to interpret them into the modified physiologically equivalent temperature (mPET) as discussed in Chen and Matzarakis [31]. As presented in their study, the predominant differences of the mPET index are the integrated thermoregulation model (based upon a multiple-segment model), and the clothing model which relays a more accurate analysis of the human bio-heat transfer mechanism.…”

“…As presented in their study, the predominant differences of the mPET index are the integrated thermoregulation model (based upon a multiple-segment model), and the clothing model which relays a more accurate analysis of the human bio-heat transfer mechanism. For this reason, the initial examination of the diurnal conditions both during the summer and winter conditions were thus presented in both PET and mPET; to firstly examine such differences identified by Chen and Matzarakis [31], and secondly, present more accurate evaluations of the human thermal comfort conditions examined later in the study.…”

Based upon the case of Lisbon, this article examined the in-situ effects of vegetation upon pedestrian thermal comfort levels. Focussing specifically upon the historic quarter that often witnesses the highest T amb values and Urban Heat Island (UHI) intensities during the summer, the most common urban canyon cases (UCCs) were modelled, along with one of the most commonly used vegetative semi-deciduous species found in the city, Tipuana tipu. Based upon a reference point (RP) system, the assessments were undertaken through the use of a new version of the SkyHelios model, local obtained G rad values, and the modified physiologically equivalent temperature (mPET) index calculated through the human-biometeorological model RayMan. The study identified the in-situ thermo-physiological influences of Tipuana tipu during different periods of the year: (1) during the summer, which revealed considerable reductions of PET/mPET of up to 15.6 • C/11.6 • C during a very hot day (where daily maximum T amb surpassed 35 • C); and (2) during the winter, which revealed the risks of oversharing as a result of the species keeping its foliage during the winter with reductions of PET/mPET of up to 2.7 • C/2.6 • C. Furthermore, the study utilised the climate tourism/transfer information scheme (CTIS) to categorise and facilitate the interpretation of the results.

High‐resolution numerical simulations were carried out for the most recent 30‐year period (1987–2016), focusing on the Euro‐Mediterranean region. A sophisticated thermo‐physiologically significant thermal index, namely the physiologically equivalent temperature (PET), was computed for assessing the thermal bioclimate of the study area and for investigating the presence of long‐term trends, focusing on bioclimatic extremes. Results indicate that the Euro‐Mediterranean thermal bioclimate follows a zonal pattern, upon which topography acts to delineate regional maxima and minima. The conducted time series analysis reveals statistically significant trends that are generally more pronounced for cold extremes. In particular, it is found that the number of days with cold (hot) stress has decreased (increased), with the distribution of PET exhibiting warming of both its cold and warm tail. The south–east Mediterranean and the Balkans are found to be the most responsive to bioclimatic changes, showing coherent and statistically significant warming trends. Overall, the results of this study provide a new point of view of the Euro‐Mediterranean climate, which could be of usefulness in a wide range of future applications. The detailed spatio‐temporal bioclimatic data could be exploited, for instance, to support applications related to tourism and recreation, highlighting regions with favourable or less favourable thermal comfort conditions. Furthermore, the trend data could be employed for quantifying the vulnerability of certain regions to cold and heat stress, in the context of public health applications.
