It is of great consensus among the scientific community that heat stress combined with air pollution, especially in urbanized areas, affect human health and activities. A variety of heat stress indices that relate atmospheric conditions to human heat sensations have already been developed. Urban environments affect the quality of life by enhanced urban heat island and in many cases control morbidity and mortality. Thus, the urban planning should take into account the human thermal sensation in order to mitigate the consequences of the urbanization and furthermore to strengthen the resilience of the society. The use of predictive models in thermal control strategies improved the thermal comfort conditions resulting in significant energy savings. The main focus of this special issue will be on the assessment/modeling of human thermal sensation within urban agglomerations. Furthermore, the urban design and ambient air pollution have a strong impact on human biometeorological conditions. The special issue will become an international forum for researchers to present the most recent developments and ideas in the field of human biometeorology, with a special emphasis given to the modeling and observational results obtained within urban environments. Potential topics include, but are not limited to:

• Observations and assessment of outdoor thermal comfort
• Spatial and temporal variability of human biometeorological indices on regional and global scale
• Urban microclimate
• Urban planning due to biometeorological assessment
• Impacts of urbanization on humans’ health
• Mitigation of urban heat island and resilience of citizens
• Air quality and thermal comfort
• Experimental measurements on human thermal sensation in urban environments
• Estimation models of human thermal sensation
• Future projections of human thermal sensation
