Аннотация: Comfort indices are used to assess the harm to human health caused by unfavorablethermal conditions. All calculated indices are based on both meteorological and physiologicalparameters. An algorithm is used which is based on a model RayMan for calculating two of themost common thermal indexes: PET and UTCI, which are based on a balance of human energyor models of human heat fluxes. The purpose of this research is to develop a real-time systemof calculating comfort indices based on data of a web service for monitoring weatherconditions in Moscow and the Moscow region. The technology is based on the use ofspecialized libraries of the Python language (pyautogui, pywinauto) to interact with the keys ofa keyboard and a mouse, because it is necessary to write paths to files and make keystrokes inthe model. The result is presented in a visually understandable form with a spatial distributionof the thermal stress in the form of points with signed index values at the locations of weatherstations throughout Moscow and the surrounding areas. A test of sensitivity of the RayManmodel to changes in a sky view factor (SVF) is also carried out. It is shown that the PET indexis more sensitive to changes in SVF than UTCI. An assessment is made of the summerfrequency of occurrence of cases with unfavorable levels of the thermal stress (taking intoaccount SVF) at stations of the Roshydromet network in Moscow and the Moscow region. It isshown that during the controversial summer of 2019, the points where strong and extreme heatstresses most often occurred are located within the territories of Domodedovo andSheremetyevo airports.
