    Authors: Mikhail Varentsov, Pavel Konstantinov, Natalia Shartova Description: The data set provides a historical reconstruction of the set of indices that represent the human thermal comfort or discomfort in outdoor environment, derived from ERA-Interim reanalysis with 0.75 ° spatial resolution on 3-hourly intervals for the period of 1979-2018, for the territory of Northern Eurasia (10°W – 170 °W, 40 °N - 80 °N). It contains five different thermal comfort indices: · Physiologically-Equivalent Temperature (PET), · Universal Thermal Climate Index (UTCI), · Heat Index (UTCI), · Humidex (HUM), · Wind Chill Temperature (WCT) The calculation of PET and UTCI indices was performed in RayMan software. The meteorological variables from the ERA-Interim reanalysis are also included. The data is separated into 40 files, that corresponds to 20x20 °cells. </p

    Intraurban social risk and mortality patterns during extreme heat events: A case study of Moscow, 2010-2017

    There is currently an increase in the number of heat waves occurring worldwide. Moscow experienced the effects of an extreme heat wave in 2010, which resulted in more than 10,000 extra deaths and significant economic damage. This study conducted a comprehensive assessment of the social risks existing during the occurrence of heat waves and allowed us to identify the spatial heterogeneity of the city in terms of thermal risk and the consequences for public health. Using a detailed simulation of the meteorological regime based on the COSMO-CLM regional climate model and the physiologically equivalent temperature (PET), a spatial assessment of thermal stress in the summer of 2010 was carried out. Based on statistical data, the components of social risk (vulnerabilities and adaptive capacity of the population) were calculated and mapped. We also performed an analysis of their changes in 2010–2017. A significant differentiation of the territory of Moscow has been revealed in terms of the thermal stress and vulnerability of the population to heat waves. The spatial pattern of thermal stress agrees quite well with the excess deaths observed during the period from July to August 2010. The identified negative trend of increasing vulnerability of the population has grown in most districts of Moscow. The adaptive capacity has been reduced in most of Moscow. The growth of adaptive capacity mainly affects the most prosperous areas of the city.The analysis of health outcomes (S. Timonin, A. Shchur) was supported by the HSE University Basic Reseach Program .The work of M. Varentsov on determining the urban canopy parameters for COSMO-CLM simulations was partially supported by Moscow Center of Fundamental and Applied Mathematics. All parts of this research except for health outcomes analysis were funded by the Russian Science Foundation (Project No. 17-77-20070 “Assessment and Forecast of the Bioclimatic Comfort of Russian Cities under Climate Change in the 21st Century”).Peer-reviewe
